Lecture 9: Chloroplasts and Photosynthesis...

Question 1

What is Oxidative Phosphorylation?

Answer 1

Energy harvested from elections, NADH & FADH2.

These molecules are oxidized and the energy released is harvested to synthesize ATP

Question 2

Where are the high energy electrons residing in Oxidative Phosphorylation?

Answer 2

NADH and FADH2

Question 3

What are the other names for Oxidative Phosphorylation?

Answer 3

Chemiosmotic coupling or chemiosmosis

Question 4

Where does Oxidative Phosphorylation occur?

Answer 4

in the plasma membrane of respiring prokaryotes and the inner mitochondrial membrane of eukaryotes

Question 5

Mitochondria have what kind of membrane?

Answer 5

Double membrane, one outer and inner.

Question 6

Describe the outer membrane of a mitochondria?

Answer 6

contains porins making it permeable to smallmolecules/ions. not proteins.

Question 7

Describe the inner membrane of a mitochondria?

Answer 7

is impermeable, extensively folded. Called Cristae

Question 8

What process occur’s in the mitochondria?

Answer 8

Glycolysis of NADH, from outside membrane with FAD + 2H from inner membrane matrix. Creating FADH2.

NADH releases 2 electrons which are picked up by FADH2
