Flashcards for Aerobic Cellular Respiration

Aerobic Cellular Respiration

Process in the mitochondria that uses O2 to breakdown C6H12O6, producing CO2, H2O, and significant energy in the form of ATP.

Glycolysis

The first step in cellular respiration, occurring in the cytosol of all cells, where one molecule of glucose is split into two molecules of pyruvate.

Pyruvate Oxidation

Step where pyruvate is converted to acetyl CoA in the mitochondria, releasing CO2.

Krebs Cycle (Citric Acid Cycle)

Cycle in the mitochondrial matrix where acetyl CoA is broken down, hydrogens are removed, and ATP is produced.

Electron Transport Chain (ETC)

A chain of enzymes in the inner mitochondrial membrane that transports electrons, creating a proton gradient.

Chemiosmotic Phosphorylation

Step involving the diffusion of protons across the inner mitochondrial membrane, producing a large amount of ATP.

Substrate-Level Phosphorylation

ATP generated through enzymes with a substrate and active site, occurring in glycolysis and the Krebs cycle.

Chemiosmotic Phosphorylation

ATP generated using ATP synthase, where the physical flow of protons through the enzyme provides energy to combine ADP and phosphate.

Beta-Oxidation

Process that breaks down fatty acids into smaller molecules (acetyl CoA) to generate energy.

Deamination

Process that removes an amino group (NH2) from a molecule, commonly an amino acid.
