Question

1. Which of the following statements is incorrect regarding mitochondrial ATP synthase?

A) ATP synthase requires 3 H+ to produce one ATP molecule.

B) The alpha subunits on the F1 complex are responsible for ATP production

C)The protein complex twists every time a H+ passes through the Fo complex

D) It produces ATP on the matrix side of the mitochondrion.

2. At which stage of aerobic respiration is oxygen used?

A) glycolysis

B) the citric acid cycle

C) electron transport chain

D) ATP synthesis

3)In photosynthesis, plants can obtain carbon by binding carbon dioxide in the air to RuBP inside the plant leaf. What enzyme is responsible for catalyzing this first reaction??

A) RNA

B) triose phosphate

C) glucose

D) rubisco

Explanation / Answer

1. The answer is
C)The protein complex twists every time a H+ passes through the Fo complex

2. The answer is
C) electron transport chain
The oxygen is the final elelctron acceptor, it receives the electrons from teminal cytochromes and forms water with protons.

3. The answer is
D) rubisco. The full form of rubisco is Ribulose 1,5 Bis phosphate corboxylase oxygenase. It is the most abount enzymes in the plant kingdom. It catalyzes both carboxylase and oxygenase reactions.
