5. Two macromolecules, such as proteins, can adhere tightly and specifically to each other. How can weak forces such as electrostatic attraction, van der Waals bonds, hydrogen bonds, and hydrophobic forces lead to such strong adherence? A. adherence can be quite strong by having many weak forces involved in molecular B. the weak forces can become very strong once non-polar groups are excluded C. the weak forces are readily converted to covalent bonds, thus leading to strong D. if the weak forces are correctly aligned they can become as strong as covalent E. adhesion is strong because the weak forces can be involved in condensation adhesion. from the inside of the molecules adherence between molecules bonds reactions 6. Condensation reactions can be used to combine multiple monomers into a polymer. Which statement(s) is (are) true concerning the molecule below? A. Arrow 1 points to a bond formed by a dehydration reaction. B. Arrow 2 points to a bond formed by a hydrolysis reaction. C. Arrow 3 points to a bond formed by a dehydration reaction D. Arrow 3 points to a bond that could be used as a substrate for hydrolysis E. Two of the above answers are correct. Он ом 7. Cyanide (CN) closely resembles molecular oxygen, and binds tightly to cytochrome C oxidase, the electron carrier that reduces O2 during aerobic respiration. Brain cells cannot ferment glucose, and therefore have to respire to utilize glucose. Cyanide is deadly to brain cells because in its presence: A. O2 builds up in the cell B. ATP cannot be synthesized from ADP C. ADP cannot be produced from ATP D. NAD+ cannot be generated from NADH E. two of these answers are correct
