Nucleic acids store and transmit hereditary, or genetic, information. When frozen, ice is less dense than liquid water (the molecules are farther apart). Unlike ionic bonds, covalent bonds do not dissociate in water. Water molecules are polar, meaning they have separated partial positive and negative charges. "As basic building blocks of life, all living organisms use nucleic acids, proteins, lipids, and carbohydrates, as well as a variety of small molecules such as metabolites, messengers, and energy carriers. 2.E: Chemistry of Life (Exercises. Instead, they're usually interacting with other atoms (or groups of atoms). Bonds break and form during chemical reactions.

Chapter 2 Chemistry Of Life Test Answer Key

Pure water has a pH of 7. Water is a polar molecule a. Polar molecules have slightly charged regions. DNA Double-Helical Structure. Some essentials of organic chemistry by listing the four biomolecules (proteins, carbohydrates, nucleic acids, and lipids), identifying the building blocks of the first three, and explaining the function of all four.

Chapter 2 The Chemistry Of Life Answer Key Figures

Others transport substances into or out of cells or help to fight disease. Chapter 2 the chemistry of life answer key.com. Not all elements have enough electrons to fill their outermost shells, but an atom is at its most stable when all of the electron positions in the outermost shell are filled. This is because sodium chloride ionic compounds form a gigantic lattice structure due to the electrostatic attractions between the individual ions. When human and rhesus monkey sequences were compared, a single difference was found in one amino acid. This process results in the release of individual water molecules at the surface of the liquid (such as a body of water, the leaves of a plant, or the skin of an organism) in a process called evaporation.

Therefore, it is possible to determine the number of neutrons by subtracting the atomic number from the mass number. Four groups of organic compounds found in living things are carbohydrates, lipids, nucleic acids, and proteins. For example, because of these forces, water can flow up from the roots to the tops of plants to feed the plant. Hydrogen bonds are also responsible for some of the three-dimensional structure of proteins. An ionic bond is formed when one or more electrons are transferred from one atom to another. Approximately how much of an increase in hydrogen ion concentration is there between tomato juice and lemon juice? Depending on the number of carbon atoms in the sugar, they may be known as trioses (three carbon atoms), pentoses (five carbon atoms), and hexoses (six carbon atoms). HelpWork: Chapter 2: The Chemistry of Life. As energy input continues, the balance between hydrogen-bond formation and destruction swings toward the destruction side. For example, hemoglobin is a globular protein, but collagen, found in our skin, is a fibrous protein. Plants synthesize glucose using carbon dioxide and water by the process of photosynthesis, and the glucose, in turn, is used for the energy requirements of the plant. Each nucleotide consists of a 5-carbon sugar, a phosphate group, and a nitrogenous base.

Chapter 2 The Chemistry Of Life Answer Key Of Life

A neutral solution has a pH of 7. Make up cell membranes 3). To learn more about water, visit the U. S. Geological Survey Water Science for Schools: All About Water! Enzymes are catalysts in living things a. Enzymes are needed for almost all processes b. The matter is defined as anything that occupies space and has mass.

Chapter 2 The Chemistry Of Life Answer Key Pdf

Starch, glycogen, cellulose, and chitin are examples of polysaccharides. Conversely, as molecular motion decreases and temperatures drop, less energy is present to break the hydrogen bonds between water molecules. 5-6 (b) Glycogen: an animal polysaccharide Starch Glycogen Amylose Chloroplast (a) Starch: a plant polysaccharide Amylopectin Mitochondria Glycogen granules 0. What functions do they serve? In most living species, glucose is an important source of energy. Most monosaccharide names end with the suffix -ose. Vitamins perform numerous functions in the body. Chapter 2 the chemistry of life answer key of life. If the pH of the body is outside of this range, the respiratory system malfunctions, as do other organs in the body. The strands are bonded to each other at their bases with hydrogen bonds, and the strands coil about each other along their length, hence the "double helix" description, which means a double spiral. D. Proteins differ in the number and order of amino acids 1). Cohesion gives rise to surface tension, the capacity of a substance to withstand rupture when placed under tension or stress.

Chapter 2 The Chemistry Of Life Answer Key.Com

The sharing of bonding pairs will ensure that the atoms achieve stability in their outer shell, similar to noble gas atoms. A fat molecule, such as a triglyceride, consists of two main components—glycerol and fatty acids. Chapter 2 chemistry of life test answer key. The orientation of the double bonds affects the chemical properties of the fat (Figure 3. Some atoms become more stable by gaining or losing an entire electron (or several electrons). Terms in this set (69). Because water is polar, with slight positive and negative charges, ionic compounds and polar molecules can readily dissolve in it.

The Chemistry Of Life Answer Key

E. Phospholipids make up all cell membranes 1). Or they might form temporary, weak bonds with other atoms that they bump into or brush up against. Essential fatty acids are fatty acids that are required but not synthesized by the human body. Sodium transfers one of its valence electrons to chlorine, resulting in formation of a sodium ion (with no electrons in its 3n shell, meaning a full 2n shell) and a chloride ion (with eight electrons in its 3n shell, giving it a stable octet). Which of the following statements is true of a neutral magnesium atom? There is no overall charge to a water molecule, but there is a slight positive charge on each hydrogen atom and a slight negative charge on the oxygen atom. During cellular respiration, energy is released from glucose, and that energy is used to help make adenosine triphosphate (ATP). Starch is the stored form of sugars in plants and is made up of amylose and amylopectin (both polymers of glucose). Atoms of an element can have different numbers of neutrons.

In sickle cell anemia, the hemoglobin β chain has a single amino acid substitution, causing a change in both the structure and function of the protein. All proteins are made up of different arrangements of the same 20 kinds of amino acids. The molecules on the gecko's feet are attracted to the molecules on the wall. All matter is composed of substances known as elements. Each element is made of atoms, each with a constant number of protons and unique properties. The basic unit of matter is the atom.

All atoms contain protons, electrons, and neutrons (Figure 3. However, fats do have important functions. Lipids include fats, oils, phospholipids, and steroids. Apart from water, the majority of molecules in living cells are carbon-based and thus are classified as organic compounds. Negative ions are formed by electron gain and are called anions. A change of one unit on the pH scale represents a change in the concentration of hydrogen ions by a factor of 10, a change in two units represents a change in the concentration of hydrogen ions by a factor of 100. C. A reaction is at equilibrium when reactants and products form at the same rate.

How many neutrons does it have? Instead of three fatty acids attached, however, there are two fatty acids and the third carbon of the glycerol backbone is bound to a phosphate group. A catalysts lowers activation energy 1. Water, for example is always evaporating, even if not boiling. The bases pair in such a way that the distance between the backbones of the two strands is the same all along the molecule. Main points include: the properties of carbon, pure forms of carbon, properties of organic compounds, polymers & monomers, elements of living things, small and large molecules in living things, carbohydrates, proteins, lipids, and nucleic acids.

The resulting bond is the peptide bond. Slight attraction can develop between the oppositely charged regions of nearby molecules. Every amino acid also has another variable atom or group of atoms bonded to the central carbon atom known as the R group. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. Recent studies have shown that an increase in trans-fats in the human diet may lead to an increase in levels of low-density lipoprotein (LDL), or "bad" cholesterol, which, in turn, may lead to plaque deposition in the arteries, resulting in heart disease.

The hydrogen bond between these hydrogen atoms and the nearby negatively charged atoms is weak and doesn't involve the covalent bond between hydrogen and oxygen. An atom has a nucleus and electrons. "Like dissolves like" a. Polar solvents dissolve polar solutes b. Nonpolar solvents dissolve nonpolar solutes c. Polar substances and nonpolar substances generally remain separate. C. Adhesion- attraction between different substances. For example, insulin is a protein hormone that maintains blood glucose levels. Lipids are also the building blocks of steroid hormones (ex- estrogen, testosterone, cortisol) and are an important constituent of the plasma membrane.

So it's basically the introduction to cell structures. The R group is the only difference in structure between the 20 amino acids; otherwise, the amino acids are identical (Figure 3. These macromolecules are built from different combinations of smaller organic molecules. Each contains a different number of protons and neutrons, giving it its own atomic number and mass number. Certain ions are referred to in physiology as electrolytes (including sodium, potassium, and calcium). This PowerPoint presentation is in two parts that covers 22 questions on the basics of carbon chemistry and organic polymers in 52 slides.
