CR & PS

FADH2 is made during

• Glycolysis

• Pyruvate oxidation

• Citric Acid Cycle

• All of the above

During which of the following steps is no ATP made–

• Glycolysis

• Electron transport chain

• Pyruvate modification

• Citric Acid Cycle

• ATP is made during all the steps

Glycolysis costs ____ATPs, but makes ___ATPs; thus it has a net yield of ___ATPs.

• a.3, 6, 3

• a.2, 4, 2

• a.2, 2, 0

• a.0, 2, 2

All of the glycolysis reactions do not require oxygen and can take place in an anaerobic environment.

• This is true

• This is false

What is the function of the coenzymes, NADH and FADH2 ?

• Charging electrons to power ATP synthase

• Catalyzing the formation of acetyl-CoA

• Providing electrons and H+ to the electron transport chain

• Transporting CO2 into the mitochondria

• Acting as a terminal electron acceptor

ATP synthase –

• Is an H+ channel

• Is embedded in the cristae of mitochondria

• Spins due to the flow of H+

• Uses rotational energy to form ATP

• All of the above

What high energy molecule is the final product of photosynthesis?

• Oxygen

• ATP

• NADPH

• Glucose

• Water

What is the function of Rubisco?

• Absorption of photon energy

• Harvesting electrons from water

• Reduction of NADP+

• Chemiosmosis

• Carbon fixation

The end product of photosynthesis is the starting material of cellular respiration.

• This is true

• This is false

Atrazine, a common herbicide, is a chemical that blocks the electron from leaving photosystem II. What would be the immediate effect on the plant?

• Prevent photon absorption

• Blocks electron harvesting from water

• Prevents ATP synthesis

• Blocks carbon dioxide absorption

• None of the above
