Glycolysis
What is the main purpose of glycolysis?
Breakdown glucose to produce energy for the cell
What is the main purpose of oxidation of pyruvate?
Convert pyruvate into Acetyl CoA so it can enter the citric acid cycle
What is the main purpose of the citric acid cycle?
Complete catabolism of glucose to produce more energy for the cell
What is the main purpose of the ETC and oxidative phosphorylation?
Use the energy stored in NADH and FADH2 to make ATP
What is the main purpose of anaerobic fermentation?
Use glucose to make ATP in the absence of oxygen
