38. When a \"high-energy\" bond of ATP is broken, primarily, what happens to the released energy?

a. It is dissipated as light.
b. It drives endergonic reactions within the cell.
c. It drives exergonic reactions within the cell.
d. It incinerates the cell.

39. Which of these is only found in RNA?

a. thymine
b. cytosine
c. uracil
d. guanin

Solution

33.The correct answer is : mitochondria

Reason: From all the organelles above, cellular respiration takes part in mitochondria.

34.The correct answer is: c.ATP

Reason:Chemiosmosis during photosynthesis or cellular generates ATP by hydrogen ions movement across the membrane.

36.The correct answer is:d.carbohydrate

Reason: Starch is a carbohydrate ; polysacharide.

37.The correct answer is:c.Dg only

Reason: DDgg will give Dg only.

38.The correct answer is:b.It drives endergonic reactions within the cell.

Reason: The energy released by ATP hydrolysis is absorbed by molecules of the endergonic reactions within a cell.

39.The correct answer is: c.uracil

Reason: Uracil is present in RNA in place of thymine.
