Glycolysis is a 10 step enzymatically catalyzed reaction which splits up a glucose molecule into two molecules of pyruvate. The process of glycolysis can occur in absence of oxygen. A net yield of 2 ATP is obtained at the end of gylcolysis for every molecule of glucose oxidized.
36 - 38 ATP from aerobic cellular respiration.
Fermentation does not produce ATP molecules during cellular respiration. Instead, fermentation occurs in the absence of oxygen to regenerate NAD+ for glycolysis to continue. This process does not directly generate ATP.
Aerobic cellular respiration produces a total of around 36-38 molecules of ATP per glucose molecule. This occurs through a series of metabolic pathways, including glycolysis, the Krebs cycle, and oxidative phosphorylation in the mitochondria.
Cellular RespirationSource: Holt Biology by Johnson Raven* Aerobic cellular respiration. Anaerobic cellular respiration yields a net gain of 2 ATP molecules for each glucose molecule broken down. Aerobic respiration yields a variable number, but always more than ten times as many ATP molecules.
in cellular respiration, there are three main steps 1) glycolysis: in this step, 2 ATP are used and 4 ATP are made, for a net of 2 ATP per glucose molecule 2) citric acid cycle (kreb's cycle): 2 ATP are made per glucose molecule 3) oxidative phosphorylation [electron transport chain and chemiosmosis]: 32 to 34 ATP are made For a total of 2 + 2 + 32 to 34 = 36 to 38 ATP created in cellular respiration
The combined sum of ATP made by glycolysis and cellular respiration is either 38 or 36, but usually 38.

Glucose is a sugar that provides energy for cellular respiration.During cellular respiration, a process called glycolysis occurs, converting glucose to pyruvate. The process releases high energy compoounds and is used for many purposes including respiration.

ATP is used for cellular respiration. It is not a product of cellular respiration.
Glycolysis is a 10 step enzymatically catalyzed reaction which splits up a glucose molecule into two molecules of pyruvate. The process of glycolysis can occur in absence of oxygen. A net yield of 2 ATP is obtained at the end of gylcolysis for every molecule of glucose oxidized.
Glycolysis itself is a process, which has many stages. It can occur throughout the cell using two ATP molecules.
Cellular Respiration is a cumulative function of three metabolic stages:Glycolysis: Breaks down glucose into two molecules of pyruvate.The citric acid cycle: Completes the breakdown of glucose.Oxidative phosphorylation: Is driven by the electron transport chain that occurs in the Mitochondria.
Aerobic cellular respiration produces a total of around 36-38 molecules of ATP per glucose molecule. This occurs through a series of metabolic pathways, including glycolysis, the Krebs cycle, and oxidative phosphorylation in the mitochondria.
