Electron Transport Chain

Question 1

Stage 1

Answer 1

ATP synthesis - Electrons are passed along the electron transport chain releasing energy.

Question 2

What is the electron transport chain?

Answer 2

The electron transport chain is a series of carrier proteins attached to the inner mitochondrial membrane

Question 3

Stage 2

Answer 3

This energy allows hydrogen ions to be pumped across the inner mitochondrial membrane.

Question 4

Stage 3

Answer 4

The flow of these ions back across the membrane protein ATP synthase results in the production of ATP

Question 5

Stage 4

Answer 5

Finally, hydrogen ions and electrons combine with oxygen to form water
