Question

The breakdown of large molecules by the enzymatic addition of water is an example of a(n)_____________ reaction oxidation reduction dehydration hydrolysis synthesis Which has more energy; table sugar (sucrose) with 12 carbons olive oil with about 55 carbons A reaction from a higher free-energy molecule to a lower free-energy molecule is exergonic endergonic unlikely to occur spontaneously dependent on combustion to start the reaction Carbohydrate produced by photosynthesis in a plant cell can: be used for respiration in the mitochondrion of the same plant cell, be transported to another plant cell and used there for respiration taken up by a cow chewing on the leaf and used for its respiration taken up by a grub chewing on the plant root and used for its respiration all of the above. Plants are green because chlorophyll absorbs green light chlorophyll does not absorb green light chlorophyll reflects red and blue light carotenoids absorb green light green light has the lowest energy The art of making bread and wine is thousands of years old. What energy-releasing pathway is responsible for both these legacies of human culture. aerobic respiration alcoholic fermentation lactate fermentation glycolysis none of the above The emperor penguins of Antarctica live on a diet of fish and crustaceans obtained from the cold Antarctic seawaters. During their annual breeding cycle, however, they migrate across the frozen continent to their breeding grounds 50 miles away from the sea (and their source of food). For more than 2 months, the male penguins care for and incubate the eggs while the females return to the sea to feed. During this time the males can lose up to 50% of their biomass (by dry weight). Where did this biomass go? The mass was released as CO2 and H2O The mass was converted to energy and used up The mass was converted into ATP molecules The mass was broken down to ammo acids and eliminated from the body The mass was convened to urine and faces and eliminated from the body A potted geranium plant is kept watered m a dark closet. After a week it will weigh less because it is still respiring, less because no photosynthesis is occurring. more because the light independent (dark reactions) Calvin cycle continues the same because no biomass is produced. more because it still has access to water and nutrients in the soil.

Explanation / Answer

1. Usually hydrolysis is a chemical process in which a molecule of water is added to a substance. Sometimes this addition causes both substance and water molecule to split into two parts. So, the correct answer is option d(hydrolysis).

2. Olive oil is a monosaturated fat. Fats are the reserve of energy. So, oilve oil will provide more energy. Option b is the correct answer.

3. Exergonic reaction is the correct answer(Option a). Exergonic reactions release free energy; the G for that reaction will be a negative value.
