Chapter 2 Chemistry Of Life Test Answer Key

In a polar covalent bond, the electrons are not shared equally by the atoms. Some vitamins are coenzymes, which means they help enzymes efficiently catalyse reactions. Plants are able to synthesize glucose, and the excess glucose is stored as starch in different plant parts, including roots and seeds. An element can donate, accept, or share electrons with other elements to fill its outer shell and satisfy the octet rule. If the pH of the body is outside of this range, the respiratory system malfunctions, as do other organs in the body. 2.E: Chemistry of Life (Exercises. High specific heat b. Cohesion- attraction between molecules of the same substance (because of hydrogen bonds, water is very cohesive). Food provides an organism with nutrients—the matter it needs to survive.

Chapter 2 The Chemistry Of Life Answer Key Figures

Nonpolar covalent bonds form between two atoms of the same element, or between atoms of different elements that share electrons more or less equally. Energy is absorbed by the reaction to make up the difference. In the food industry, oils are artificially hydrogenated to make them semi-solid, leading to less spoilage and increased shelf life. The appendix also contains bacteria that break down cellulose, giving it an important role in the digestive systems of some ruminants. Some are in charge of metabolism, while others regulate cell and tissue growth and differentiation. Chapter 2 the chemistry of life answer key west. D. the double bond in hydrocarbon chains. Slight attraction can develop between the oppositely charged regions of nearby molecules. Click here to see a 3-D animation of the structure of an ice lattice. The sharing of bonding pairs will ensure that the atoms achieve stability in their outer shell, similar to noble gas atoms. Fatty acids may be saturated or unsaturated. This particular ratio of Na ions to Cl ions is due to the ratio of electrons interchanged between the 2 atoms. Increase reaction rate.

This causes a change in protein structure and function. What is life made up of? In this case, it is easier for chlorine to gain one electron than to lose seven, so it tends to take on an electron and become Cl. Polymers are formed when several monomers bond together. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. Chapter 2 the chemistry of life answer key lime. Water's role in life by recognizing that the abundance and polar properties of water make it critical to biology, describing its critical role as a solvent for biological molecules. Arachidic acid is derived from Arachis hypogaea, the scientific name for peanuts. Enzymes can function to break molecular bonds, to rearrange bonds, or to form new bonds. The unique three-dimensional structure of a polypeptide is known as its tertiary structure. The chemical formula for glucose is C6H12O6. Is there ever an instance where both the intermolecular bonds and intramolecular bonds break simultaneously?

Chapter 2 Chemistry Of Life Test Answer Key

This is because the water molecules are attracted to the straw and therefore adhere to it. Saturated fatty acids are saturated with hydrogen; in other words, the number of hydrogen atoms attached to the carbon skeleton is maximized. An ion is an atom that has gained or lost one or more electrons a. Monosaccharides (mono- = "one"; sacchar- = "sweet") are simple sugars, the most common of which is glucose. Lipids perform many different functions in a cell. It takes less energy for sodium to donate that one electron than it does to accept seven more electrons to fill the outer shell. Chapter 2 chemistry of life answer key. Whenever glucose levels decrease, glycogen is broken down to release glucose. Cells are made up of organic and inorganic molecules, which are made up of atoms that have been bonded together. Frequently Asked Questions – FAQs. However, fats do have important functions.

Chapter 2 The Chemistry Of Life Answer Key West

Carbohydrates are made of carbon, hydrogen, and oxygen a. Carbohydrates include sugars and starches nosaccharides are simple (single) sugars c. Disaccharides are double sugarsDisaccharides. Because water is polar, with slight positive and negative charges, ionic compounds and polar molecules can readily dissolve in it. Starch is the stored form of sugars in plants and is made up of amylose and amylopectin (both polymers of glucose). Cells are surrounded by a membrane, which has a bilayer of phospholipids (Figure 3. However, not all bonds between elements are ionic or covalent bonds. Chemistry of Life - What is Chemistry of Life? What are the Inorganic and Organic Compounds in Chemistry essential for life? Along with FAQs. Which type of bond represents a weak chemical bond?

Ionic bonds form between oppositely charged ionsIonic bonds. Chlorine (Cl), on the other hand, has seven electrons in its outer shell. The carbon atoms may bond with atoms of other elements, such as nitrogen, oxygen, and phosphorus (Figure 3. There are two kinds of nucleic acids: ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). Because of this change, the disc-shaped red blood cells assume a crescent shape, which can result in serious health problems. D. all of the above. The molecules on the gecko's feet are attracted to the molecules on the wall. Water is, therefore, what is referred to as a solvent—a substance capable of dissolving another substance. Each of these classes of compounds is made up of large molecules that are made up of small subunits. Have you ever filled up a glass of water to the very top and then slowly added a few more drops? High H+ concentration b. pH less than 7.

Many contain carbon chains called fatty acids b. Fats and oils contain fatty acids bonded to glycerol. Pure water has a pH of 7. Every other glucose monomer in cellulose is flipped over and packed tightly as extended long chains.
