In Cellular Respiration, _______

Question

In cellular respiration, _______.
A) air enters the bronchi
B) oxygen passes through the thin walls of the alveoli
C) cells use oxygen to capture energy from nutrients
D) oxygen is transported as oxyhemoglobin to the cells

Accepted Answer

Cellular respiration is a metabolic process that occurs in cells, where glucose and oxygen are broken down to release energy in the form of ATP (adenosine triphosphate). This process involves a series of reactions that take place in the mitochondria of cells, and oxygen is a necessary component in order for ATP to be produced. Therefore, cells use oxygen to capture energy from nutrients in the process of cellular respiration. Option A describes the process of breathing, while options B and D refer to the transport of oxygen in the body.
