Cellular Respiration and ATP Production Quiz

Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor, such as oxygen, to drive the bulk production of adenosine triphosphate (ATP), which contains energy.

The main steps of cellular respiration are glycolysis, the Krebs cycle (also known as the citric acid cycle or tricarboxylic acid cycle), and oxidative phosphorylation.

Glycolysis occurs in the cell's cytoplasm.

<p>The three main stages of cellular respiration are glycolysis, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation (also known as the electron transport chain). Glycolysis occurs in the cell's cytoplasm, while the citric acid cycle and oxidative phosphorylation occur in the mitochondria.</p> Signup and view all the answers
