Question

Q
Which statement BEST explains how energy is transferred in cellular respiration?
C) Chemical energy from glucose is released slowly and over a series of steps when it reacts with oxygen. The chemical energy released is used to form ATP, which is then used to power biochemical processes.
B) Chemical energy from glucose is stored by individual cells with the help of oxygen during cellular respiration. The chemical energy is then released in the form of light and heat.
A) Chemical energy from glucose is released during cellular respiration. After glucose reacts with oxygen. the heat energy is stored by individual cells over a series of steps.
D) Chemical energy from glucose, oxygen and carbon dioxide is stored in cells during the last stage of cellular respiration. The chemical energy is released all at once in the form of ATP, which is then used up by the cell.

Answer 1

The statement that BEST explains how energy is transferred in cellular respiration is:

**C) Chemical energy from glucose is released slowly and over a series of steps when it reacts with oxygen. The chemical energy released is used to form ATP, which is then used to power biochemical processes.**

This statement accurately describes the process of cellular respiration, where glucose is broken down in a series of enzymatic reactions, gradually releasing energy that is captured in the form of ATP. This method of energy release ensures that cells can effectively utilize the energy stored in glucose for various biological functions.
