Answer:
Cells obtain energy from food from the catabolism of glucose. These processes are called:
→ Glycolysis: process in which glucose is broken down to obtain four molecules of adenosine triphosphate (ATP) and two of pyruvate.
→ Citric acid cycle or Krebs cycle: it is a process that occurs within the mitochondria in the presence of oxygen, resulting in one molecule of acetyl-CoA, two of ATP and two of CO₂.
→ Oxidative phosphorylation: this last stage of cellular respiration takes place in the mitochondrial membrane and occurs in two phases:
