Question

A researcher estimates that, in a certain organism, the complete metabolism of glucose produces 30 molecules of ATP for each molecule of glucose. The energy released from the total oxidation of glucose under standard conditions is 686 kcal/mol. The energy released from the hydrolysis of ATP to ADP and inorganic phosphate under standard conditions is 7.3 kcal/mol. Calculate the amount of energy available from the hydrolysis of 30 moles of ATP. Calculate the efficiency of total ATP production from 1 mole of glucose in the organism. Describe what happens to the excess energy that is released from the metabolism of glucose.

Answer 1

Answer:

The correct answer will be-

1. energy from 30 moles- 219 kcal

2. efficiency- 31.9%

3. excess energy- is lost as heat

Explanation:

1. Energy from 30 moles

Hydrolysis of 1 ATP = 7.3 kcal/mol.

Hydrolysis of 30 ATP = 30 x 7.3

                                  = 291 kcal

2. Efficiency

1 mole of glucose produce = 30 ATP (219 Kcal)

1 mole of glucose release = 686 kcal

Therefore, efficiency will be = $\frac{energy produced }{energy released by 1 mole of glucose} \times100$x 100

                                     = 31.9 %

3. The excess amount of energy is released in the form of heat.
