Select one:

a. True

b. False

2. Energy released by transferring electrons along the electron transport chain is stored most immediately as potential energy in the form of:

Select one:

a. None of the other answer options are correct.

b. a proton gradient.

c. ATP.

d. weak covalent bonds in carbohydrates and lipids.

e. reduced forms of electron carriers.

Answer 1

Q1. True. Biological system operate according to physical and chemical principles. Cells in the biological systems interact with one another through chemical processes like hormones. Cells or biological system need energy in the form of food is an example of physical property.

Q2. Option C is correct . ATP.

ATP are synthesised in the ATP synthase enzyme. They have high potential for energy.

ATP is also known as energy currency of the cell because it can be easily used as energy source for various mechanisms.
