Why are carbohydrates important molecules for energy storage?
a. The C—H bonds found in carbohydrates store energy.
b. The double bonds between carbon and oxygen are very strong.
c. The electronegativity of the oxygen atoms means that a carbohydrate is made up of many polar bonds.
d. They can form ring structures in the aqueous environment of a cell.

- Which category of macromolecule always contains lots of carbon, hydrogen, oxygen, nitrogen, andsulfur, but does not contain any phosphorus (when first synthesized)?A. polynucleotides (like ribonucleic acid)B. carbohydrates (like glucose)C. proteins (like insulin)D. lipids (like triglycerides)E. polysaccharides (like glycogen)arrow_forwardHow is the structure of saturated fats different from that of unsaturated fats? A. All of the carbons in the hydrocarbon tails of saturated fats are bonded to one another with double bonds. B. Saturated fats have three hydrocarbon tails bonded to the glycerol molecule instead of just two. C. The hydrocarbon tails in a saturated fat have the maximum number of hydrogens possible. D. Saturated fats have no oxygens present. What are the primary functions of carbohydrates in cells? A. Energy storage, cell identity, structure, and building blocks for synthesis. B. Catalysis, structure, and energy storage. C. Different orientation of a hydroxyl in the ring form. D. Different position of the carbonyl group in the linear form. A positive test for starch would give the following colors: A. Dark blue, black, or purple B. Red, yellow, orange-red, green C. Bright Purple D. Purely Bluearrow_forwardCells can store energy as starches (long polymer forms of carbohydrates, or sugars) and fats. If you isolate the starch stored by a cell, you would find that a lot of the mass of the isolated starch is actually water. However, if you isolate the fat stored by a cell you would find that very little of the mass of the fat is water. Explain this difference based on the structures or properties of the starch and fat moleculesarrow_forward
- Which of the following polysaccharides is used as an energy-storage molecule in plants?a. glycogenb. chitinc. starchd. cellulosearrow_forwardWhy can a monosaccharide theoretically form diverse disaccharides? a. Because it is classified as an aldose or ketoseb. Because it is a right-handed moleculec. Because it has multiple hydroxyl groups that can form glycosidic bond.d. Because it has several carbonyl groups that can form glycosidic bond.arrow_forwardWhich of the following statements concerning fatty acids is correct? a. Used to make phospholipids b. They all contain one or more double bonds. c. They are a constituent of sterols. d. They are strongly hydrophilic.arrow_forward
- Starch, glycogen, and cellulose are all composed of long chains of glucose molecules. While starch and glycogen are often branched, cellulose is always straight due to hydrogen bonding between neighboring strands. How is this structural difference advantageous for the function of cellulose? * 1. Cellulose is used as long-term energy storage, held tightly together to take up minimal space. 2. The lack of branching allows cellulose to be easily hydrolyzed, enabling it to be used as quick energy. 3. Cellulose is a structural polysaccharide, used as support in exoskeletons. 4. Cellulose is held tightly together in order to offer support in cell walls.arrow_forwardWhich of the following is not a function of lipids? A. They catalyze reactions and reduces activation energy B. Main component of the cell membrane C.Used in cooking and as alternative fuel sources D. Long term energy storagearrow_forwardWhich of the following statements is False?a. In starch breakdown, water is formed.b. In chitin, glucoses are linked as in cellulose.c. Peptide bonds determine primary peptide structure.d. Disulfide bridges are formed by covalent bonds.arrow_forward
