Cellular respiration turns glucose into energy.

C. Cellular respiration

Step-by-step explanation:

The process of cellular respiration turns glucose into energy.

Cellular respiration is usually split into 3 steps: glycolysis, Krebs cycle, and the electron transport chain.

Glycolysis breaks glucose down into 2 pyruvic acids and also produces 2 ATP.

The Krebs cycle then breaks these down into 4 CO2 molecules, electron carriers (FADH2 and NADH), and 2 molecules of ATP.

These electron carriers give up electrons and hydrogen ions in the ETC, creating enough energy to produce a net of 34 ATP.

You can see that the 3 steps of cellular respiration produce ATP (energy), and that is why the correct answer is cellular respiration.
