Which of the following best describes aerobic respiration?
a. The production of ATP from glucose in the presence of oxygen
b. The production of pyruvate in the absence of oxygen
c. The production of pyruvate using energy from the sun
d. The production of ATP from glucose in the absence of oxygen
Introduction:
The process in which energy required for cellular functions is released in the presence of oxygen is called as aerobic respiration. It is a multistep process in which the body cells break down food in mitochondria to release energy. ATP is the form of energy released by cellular respiration.
Answer to Problem 1MCQ
Correct answer:
Aerobic respiration requires oxygen and carbohydrates to produce ATP, which is the energy form required for various cellular processes. Therefore option a. is the correct answer.
Explanation of Solution
Reason for the correct statement:
In aerobic respiration, the first step is the breakdown of glucose molecules into carbon dioxide and water to release ATP. This process is known as glycolysis.
Option a. is given as “the production of ATP from glucose in the presence of oxygen”.
As, “the production of ATP from glucose in the presence of oxygen best describes the aerobic respiration”, is the right answer.
Hence option a. is correct.
Reasons for the incorrect statements:
Option b. is given as “the production of pyruvate in the absence of oxygen”.
The production of pyruvate in the absence of oxygen is a process of anaerobic respiration. So, it is a wrong answer.
Option c. is given as “the production of pyruvate using energy from the sun”.
The production of pyruvate takes place from the process of glycolysis and not from the energy of sun. So, it is a wrong answer.
Option d. is given as “the production of ATP from glucose in the absence of oxygen”.
Aerobic respiration requires the presence of oxygen. So, it is a wrong answer.
Hence, options b., c., and d. are incorrect.
Aerobic cellular respiration involves the breakdown of glucose molecules in the presence of oxygen to release water, carbon dioxide and ATP.
