Summary Introduction

Introduction:

Aerobic respiration is a process where glucose and oxygen take part in a chemical reaction and produce energy which is transferred to the cells, making two waste products: carbon dioxide and oxygen. Therefore, it releases energy which the cell traps in the bonds of ATP.

Answer to Problem 1MCQ

Correct answer:

The process that produces ATP from glucose in the presence of oxygen is called aerobic respiration. Hence, the correct answer is option a.

Explanation of Solution

Reason for correct answer:

Option a. is given as, “The production of ATP from glucose in the presence of oxygen.”

Aerobic respiration is the process where ATP (Adenosine Triphosphate) is obtained from glucose molecules in the presence of oxygen. The food is broken down by the cells in mitochondria in multiple steps leading to the generation of 36ATP molecules. Glycolysis, citric acid cycle and electron transport chain are the three mechanisms through which ATP is produced from glucose in the presence of oxygen. Hence, option a. is correct.

Reason for incorrect answer:

Option b. is given as, “The production of pyruvate in the absence of oxygen.”

In the presence of oxygen, pyruvate obtained from glycolysis is converted to acetyl CoA to enter into the Krebs cycle. Hence, option b. is incorrect.

Option c. is given as, “The production of pyruvate using energy from the sun.”

Pyruvate obtained by glycolysis uses energy from ATP, and not from the sun. Hence, option c. is incorrect.

Option d. is given as, “The production of ATP from glucose in the absence of oxygen.”

ATP molecules are also produced during anaerobic respiration through the process of anaerobic glycolysis. However, this statement does not describe aerobic respiration. Hence, option d. is incorrect.

Hence, the options b., c., and d. are incorrect.

Conclusion

The ATP is produced from glucose in the presence of oxygen in aerobic respiration. Thus, the correct answer is option a.
