Art-Ranking Activity: The electron transport chain and oxidative phosphorylation

Solutions

Expert Solution

Art ranking activity of Electron Transport chain -

1. REDOX OF NADH+H+ AT COMPLEX 1, electrons go to complex 1, four protons pumped from matrix to intermembrane space

2. REDOX OF FADH2 AT COMPLEX 2, Coenzyme Q picks up electrons (from complex 1&2) and transports to complex 3

3. REDOX OF COMPLEX 3, four protons pumped from matrix to intermembrane space, carrier C transports electrons to complex 4

4. REDOX OF COMPLEX 4, two protons pumped from matrix to intermembrane space, formation of H2O

5. ATP SYNTHASE ACTION, pumps protons from intermembrane space to matrix, produces ATP from ADP + Pi + energy.

Electron transport chain is a component of oxidative phosphorylation, specifically the part that uses oxygen. Oxidative phosphorylation is the use of ETC to put electrons onto oxygen forming water, simultaneously creating a proton gradient across the mitochondrial inner membrane that is consumed to phosphorylate ADP making ATP
