Question 1

True or False: the equation for cellular respiration is C6H12O6 + 6O2 = 6CO2 + 6H2O + energy. Glucose + Oxygen = Carbon Dioxide + Water + Energy.

Answer 1

True.

Question 2

What is oxidation?

Answer 2

The loss of electrons during a chemical reaction.

Question 3

What is reduction?

Answer 3

Electrons are gained during a chemical reaction.

Question 4

Does cellular respiration include three stages: glycolysis, Krebs cycle, and electron transport?

Answer 4

Yes.

Question 5

What is the substrate level called?

Answer 5

Phosphorylation.

Question 6

NAD+ and NADH, FAD and FADH2 are carriers of high energy electrons called c _ _ _ _ _ _ _ s

Answer 6

Coenzymes.

Question 7

How do the electron transport chain and ATP synthase power cellular respiration?

Answer 7

The electron transport chain transports electrons to pump protons across the inner mitochondrial membrane. This drives the synthesis of ATP.

Question 8

How is oxygen consumed in cellular respiration?

Answer 8

Oxygen combines with electrons and two hydrogen ions to make water. Then hydrogen ions flow through ATP synthase and combine with ADP and phosphate group to form ATP.
