Electron Transport Chain

Question 1

Stage 1

Answer 1

NADH passes electrons and hydrogen ions to electron transport chain

Question 2

Stage 2

Answer 2

Electrons are passed along electron transport chain releasing energy by the use of membrane carrier proteins

Question 3

Stage 3

Answer 3

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

Question 4

4

Answer 4

The flow of these hydrogens ions back through the membrane protein ATP sythase results in making of ATP

Question 5

5

Answer 5

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