Week 3: Aerobic Glycolysis and Oxidative Phosphorylation

Flashcards for Week 3 Lecture Notes

Aerobic Metabolism

Metabolic process that uses oxygen to produce energy.

Oxidative Phosphorylation

The final stage of cellular respiration, where ATP is produced.

Acetyl coA production

First Stage of Oxidative Phosphorylation

Krebs Cycle

A series of chemical reactions that extract energy from molecules, releasing carbon dioxide and producing high-energy electron carriers.

Electron Transport Chain

A series of protein complexes that transfer electrons, creating a proton gradient to drive ATP synthesis.

Citric Acid Cycle

Another name for the Krebs Cycle

TCA cycle

Another name for the Krebs Cycle

Function of Krebs Cycle

Remove hydrogen atoms from organic molecules and transfer them to coenzymes

ATP from Glycolysis

2 ATP

ATP from CAC

2 ATP

CAC turns

Occurs twice per glucose molecule

1 NADH

For every 10 H+ pumped across, 3 H+ come back to form ATP

1 FADH2

For every 6 H+ pumped across, 3 H+ come back to form ATP

Adenine nucleotide translocase

ATP and ADP are transported in and out using an ‘antiport’

Phosphate transport

A similar antiport system
