Question

28. Which of the following polymers of glucose is used as a vehicle to store energy reserves in animal cells? (a) glycogen (c) starch (b) glucagorn glycerol 29. In the final step of the citric acid cycle, oxaloacetate is regenerated through the oxidation of malate and this is coupled with the production of which other molecule? (a) NADH FADH2 (c) GTP (d) CO2 30. The link between bond-forming reactions and membrane transport processes in the mitochondria is called (a) electron transfer (c) ATP synthesis (b) proton pumping ) chemiosmotic coupling 31. In the light reaction of photosynthesis, light energy is harnessed to produce (c) Glucose only (a) ATP only (b) NADPH only both a and b 32. The light reaction of photosynthesis helps to build up protons in the of chloroplast? stroma (c) intermembrane space

Explanation / Answer

(28)a.glycogen

In animals glycogen is the stored form of carbohydrate. Glucagon is a hormone and glycerol is non carbohydrate

(29)a. NADH

NADH is a reduced equivalent of NAD+, which is formed during oxidation of malate to oxaloacetate.

(30)d.chemiosmotic coupling

(31)d. Both a and

Light reactions of photosynthesis produce small amount of ATP and NADPH

(32) Thylakoid space
