Question

1. what protein complex in the inner mitochondrial membrane allows protons to return to the matrix?

a. cytochrome b. electron transport carriers c. F0F1 d. NADH dehydrogenase e. porin

2. The process where ADP is converted to ATP while coupled to the electron transport chain is?

a. citric acid cycle b. alcohol fermentation c.oxidative phosphorylation d. chemiosmotic hypothesis

3. The majority of ATP produced during the catabolism of glucose is formed during?

a. oxidative phosphorylation b. glycolysis c. the citric acid cycle d. lipogenesis e. acetly- CoA formation

4. each turn of the citric cycle produces ...?... of NADH coenzyme(s)

a. 1 b. 2 c.3 d.6 e.18

5. Each turn of the citric acid cycle produces ...?... molecules of CO2

a. 2 b. 3 c. 4 d. 5 e.6

Explanation / Answer

1. c. F0F1

F0F1 ATPase (or ATP synthase) protein complex present in the inner mitochondrial membrane provodes channel for the protons (H+) to return to the matrix.

2). c.oxidative phosphorylation

“Oxidative phosphorylation” is an aerobic process that involves a series of reactions, which include the transfer of electrons from the NADH or FADH2 to oxygen. This process involves the transfer of electrons (oxidation) by a series of electron carriers (electron transport system (ETS)) and attachment of phosphate group (phosphorylation). Oxidative phosphorylation is the main metabolic process through which ATP (adenosine triphosphate) is generated.

3. a. Oxydative phosphorylation.

4. c. 3

Each citric acid cycle produces 1 FADH, 3 NADH, 1 GTP along with 2 CO2.

5. a. 2

Each citric acid cycle produces 1 FADH, 3 NADH, 1 GTP along with 2 CO2.
