Cellular Respiration

What is the main source of energy for cellular respiration?

• glucose

• amino acids

• triglycerides

• oxygen

It is the process in which organisms breaks down glucose from food to create ATP.

• Cellular Respiration

• PHotosynthesis

• Digestion

• Respiration

During_______, glucose molecules are broken down into smaller pyruvate molecules.

• Krebs Cycle

• Electron Transport Chain

• Glycolysis

• Oxidative Phosphorylation

During glycolysis, 6 carbon -carbon glucose is broken into:

• 1 molecule of 6-carbon fructose

• 2 molecules of 3-carbon pyruvic acid or pyruvate

• 2 ATP

• 1 NADPH

The burning sensation of the muscles when undergoing anaerobic respiration is due to the_______
