glycolysis + krebs cycle

Overview of glycolysis

One molecule of glucose is broken down into two molecules of pyruvate

What are the key steps of glycolysis?

Energy investment - requires ATP to phosphorylate glucose

Cleavage phase - glucose is split into 2 GP

Energy liberation - ATP and NADH are produced, and the GP are converted to pyruvate

What is an overview of the Krebs cycle (citric acid)?

The citric acid completes the breakdown of pyruvate which was generated from glycolysis

What are the key steps of Krebs cycle?

Acetyl-CoA formation - pyruvate is converted to acetylene-CoA producing NADH

Citric acid cycle - Acetyl-CoA enters the cycle producing NADH, FADH2 and GTP

Carbon dioxide is released

Where does oxidative phosphorylation take place?

Inner mitochondrial membrane

What is an overview of oxidative phosphorylation?

ETC and chemiosmosis work together to generate ATP using the energy released from when electron are transferred

What are the key steps to oxidative phosphorylation?

Electrons from NADH and FADH2 move though ETC

Energy released pumps protons across the membrane creating an electrochemical gradient

Protons flow back through ATP synthase, synthesising ATP

Oxygen acts as the final electron acceptor, forming water.
