The correct answer is: C.Cellular respiration

Explanation:

The majority of ATP in cells is produced through a process known as cellular respiration. This process occurs in several stages, including glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation (which includes the electron transport chain and chemiosmosis).

Why the other options are incorrect:

A.Photosynthesis: This process occurs in plants, algae, and some bacteria, where sunlight is used to convert carbon dioxide and water into glucose and oxygen. While photosynthesis does produce ATP, it is primarily for the purpose of s...
