Chemiosmosis

Question 1

Where does chemiosmosis get its energy from?

Answer 1

H+ ion gradient built up by ETC

Question 2

What is chemiosmosis?

Answer 2

Diffusion of ions across membrane down concentration gradient (high to low)

Question 3

What facilitates chemiosmosis? What role does this play?

Answer 3

ATP synthase- Synthesizes ATP by letting H+ ions diffuse down the concentration gradient, which lets ADP get phosphorylated into ATP

Question 4

How does oxidative phosphorylation work?

Answer 4

ETC redox reactions and chemiosmosis power phosphorylation and make lots of ATP

Question 5

What layers does mitochondria have, outside to inside?

Answer 5

Cytoplasm, outer membrane, intermembrane space, inner mitochondrial membrane, mitochondrial matrix

Question 6

What protein is embedded in the inner mitochondrial membrane?

Answer 6

ATP synthase

Question 7

In the end, how is ATP generated during chemiosmosis? (HOW most ATP is produced)

Answer 7

Oxidative phosphorylation
