Question

A student found the following flowchart in a textbook.

Glycolysis
Krebs cycle
Electron transport chain
Which statement is the best summary of the process shown?
A. Solar energy is converted and stored in chemical bonds.
B. Chemical energy is converted to kinetic energy
C. Energy from sunlight moves through trophic levels.
D. Energy in food is released and stored in ATP molecules.
I

Answer 1

D. Energy in food is released and stored in ATP molecules

Step-by-step explanation:

The flow chart in this question, which is as follows, is describing the process of cellular respiration.

Glycolysis → Krebs cycle → Electron transport chain

Cellular respiration is the metabolic process by which chemicals in food molecules (glucose) is broken down to release energy usable by the cells called ATP. It involves the three stages as depicted by the flowchart above.

Therefore, according to the question, the process described is a summary of how "Energy in food is released and stored in ATP molecules".
