Glycolysis Products in Cellular Respiration

Glycolysis is the first step of cellular respiration and breaks glucose into smaller molecules. Cells use this process to pull energy from glucose over a series of chemical reactions. Cellular respiration can happen with oxygen or without oxygen.

In both aerobic and anaerobic cellular respiration...

Glycolysis can be divided into two phases—the energy requiring phase and the energy releasing phase.

In the first phase, two ATP molecules are used to split the glucose into two molecules of glyceraldehyde-3-phosphate. In the second phase, the intermediate sugar is further catabolized to produce four ATP, two NADH, and two pyruvate molecu...
