Biochemistry C784 Module 4. The polysaccharide cellulose is composed of sugar monomers linked through linkages, with their CH2OH groups in direction relative to the neighboring monomer. Select one: a. Beta; opposite Correct! Polysaccharides of nondigestible Carbohydrates (the "fiber" in our diets) are held together by bonds known as beta linkages between individual monosaccharides; their CH2OH groups are orientated in an opposite direction relative to its neighbors. These bonds make cellulose indigestible in our bodies. b. gamma; same c. alpha; opposite d. beta; same Which of the following nutrients cannot be broken down to a substance that can participate in the production of ATP via aerobic cellular metabolism? Select one: a. Vitamin E Correct! Vitamins are not nutrients that can be broken down in the process of creating ATP; rather they are essential in small quantities to serve as coenzymes or cofactors in enzymatic processes.Vitamin E is an antioxidant b. Lipids c. Protein d. Complex Carbohydrates Glycolysis produces two ATP molecules. Through what process are these ATP molecules made? Select one: a. Substrate level phosphorylation Correct! The reactions within glycolysis directly form a bond between ADP and Pi to form ATP in the process of substrate level phosphorylation b. Oxidative phosphorylation c. Electron transport chain d. Beta oxidation What product of beta oxidation is able to enter the citric acid cycle? Select one: a. Acetyl CoA Correct! Acetyl CoA made by the process of beta oxidation enters the citric acid cycle b. Glucose c. Glycerol d. Fatty acyl-CoA What process is shared between anaerobic and aerobic Metabolism ? Select one: a. Glycolysis Correct! The pyruvate produced in glycolysis will have different fates based on the availability of oxygen, but glycolysis will occur regardless of oxygen's presence or absence. b. Lactate fermentation c. Electron transport chain
