Cellular Respiration

Question 1

Describe cellular respiration

Answer 1

Catabolic exothermic reaction that occurs in four stages in three different parts of the cell

Question 2

Give the four stages of cellular respiration

Answer 2

Glycolysis, pyruvate oxidation, Kreb’s cycle (citric acid cycle), electron transport chain

Question 3

Briefly describe glycolysis

Answer 3

10 step anaerobic enzymatic process that occurs in the cytoplasm, splitting six-carbon glucose molecules into two three-carbon molecules

Question 4

Briefly describe pyruvate oxidation

Answer 4

One step process in the matrix of the mitochondria. Decarboxylation occurs to the pyruvate molecule

Question 5

Briefly describe the Kreb’s cycle (citric acid cycle)

Answer 5

8-step enzyme-controlled cycle in the matrix of the mitrochondria. Makes a net two ATP through SLP

Question 6

Briefly describe the electron transport chain

Answer 6

Occurs in the cristae (inner mitochondrial membrane) and the matrix. Produces the bulk of the ATP via oxidative phosphorylation

Question 7

What is the final product of cellular respiration?

Answer 7

Water

Question 8

Review a diagram of the stages of cellular respiration
