Question

The electron carrier molecules and cytochrome :
1) Are reduced as they pass electrons on to the next molecule
2) Transfer of electrons between the electron carrier complexes
3) Shuttle protons to ATP synthase
4) Are found in outer mitochondrial membrane

Answer 1

I think 3) shuttle proton to ATP synthase

Answer 2

Answer:

2) Electron transfer between electron carrier complexes

Explanation

Electrons are transmitted from one patch to the coming in the electron transport chain, and the energy generated during these electron transfers is employed to produce an electrochemical grade. The energy stored in the grade is used to produce ATP in chemiosmosis.

Explanation for incorrect answers

1) Aren't reduced as they pass electrons on to the coming patch.

3) Shuttle protons to PMF synthase.

4) Are set up in inner membrane.
