Lecture 3: Cellular Respiration

Question 1

4 Metabolic Stages of Cellular Respiration

Answer 1

(1) Glycolysis
(2) Pyruvate oxidation
(3) Krebs Cycle
(4) Electron Transport Chain

Question 2

The step-by-step breakdown of high-energy glucose molecules to release energy

Answer 2

Cellular Respiration

Question 3

Where does glycolysis occur?

Answer 3

In the cytosol

Question 4

Where does the Krebs Cycle occur?

Answer 4

The mitochondrial matrix

Question 5

Where does the Electron Transport Chain (ETC) occur?

Answer 5

In the inner mitochondrial membrane

Question 6

The fundamental mode of energy exchange in a biological system.

Answer 6

ATP-ADP Cycle

Question 7

How much energy is released during the ATP-ADP Cycle?

Answer 7

7 kilocalories of energy

Question 8

Types of Cellular Respiration

Answer 8

(1) Aerobic Respiration
(2) Anaerobic Respiration

Question 9

Releases large amounts of energy when chemically breaking down glucose completely

Answer 9

Aerobic Respiration

Question 10

Glucose is incompletely broken down; produces a lot less energy and most of it is lost as heat

Answer 10

Anaerobic Respiration

Question 11

What are the products of glycolysis?

Answer 11

(1) 2 pyruvate molecules
(2) 2 ATP molecules
