Study Notes

Inputs and Outputs of Cellular Respiration

Glycolysis requires glucose, 2 ATP, 2 NAD+, and 4 ADP + P to initiate the process.
Glycolysis produces 2 pyruvates, 4 ATP (with a net gain of 2 ATP), 2 NADH + H+, and 2 H2O as outputs.

Preparatory Stage of Cellular Respiration

The preparatory phase utilizes 2 pyruvate, 2 CoA, and 2 NAD+ as inputs.
It results in the formation of 2 acetyl CoA, 2 CO2, and 2 NADH + H+.

Kreb Cycle (Citric Acid Cycle)

Inputs for the Kreb Cycle include 2 acetyl CoA, 2 oxaloacetate, 2 ADP + P, 6 NAD+, and 2 FAD.
The outputs consist of 4 CO2, 2 ATP, 6 NADH + H+, and 2 FADH2.

Electron Transport Chain (ETC)

The ETC requires 10 NADH + H+ and 2 FADH2.
It produces 10 NAD+, 2 FAD, H2O, and 34 ATP, highlighting its role in energy production.

Fermentation Process

Fermentation starts with inputs of glucose and 2 ATP.
The process leads to outputs of either 2 lactate or 2 alcohol with 2 CO2, along with a total of 4 ATP (net gain of 2 ATP).
