Flashcards

Aerobic Glycolysis

The breakdown of glycogen into glucose-6-phosphate, which is then converted to pyruvic acid, generating a small amount of ATP (2 ATP).

Acetyl Coenzyme A

A coenzyme that plays a crucial role in aerobic energy production by carrying acetyl groups to the citric acid cycle.

Citric Acid Cycle

A series of chemical reactions in mitochondria that extract energy from acetyl CoA, producing ATP and carbon dioxide as byproducts.

Electron Transport Chain (with NADH2)

A process that occurs in mitochondria, involving the transport of electrons through a chain of proteins, which ultimately generates large amounts of ATP (30 ATP) using NADH2.

Electron Transport Chain (with FADH2)

A process within the electron transport chain that harvests energy from the electron movement, producing a smaller amount of ATP (4 ATP) using FADH2.

Study Notes

Aerobic Glycolysis

Glycogen is broken down by glycogen phosphorylase (GP) into glucose-6-phosphate.
Glucose-6-phosphate is converted into pyruvic acid, releasing 2 ATP.
Pyruvic acid is converted to acetyl CoA by coenzyme A.
Acetyl CoA combines with oxaloacetic acid to form citric acid.
The citric acid cycle repeats, producing ATP and carbon dioxide.
Hydrogen is released as a byproduct.
NADH2 carries hydrogen in the electron transport chain, producing 30 ATP.
FADH2 carries hydrogen, producing 4 ATP.
