Chapter 4 - Respiration

Question 0

Where does glycolysis occur?

Answer 0

In the cytoplasm of the mitochondria.

It can occur in the absence of oxygen.

Question 1

What are the four stages of aerobic respiration?

Answer 1

Glycolysis, the Link Reaction, the Krebs Cycle and Oxidative Phosphorylation

Question 2

What are the steps of Glycolysis? And what are the products?

Answer 2

Glucose (6C)
         >
Glucose Phosphate (6C)
         >
Glucose Biphosphate (6C)
         >
2 x Triose Phosphate (3C)
         >
2 x Pyruvate (3C)

Produced:
2 x Pyruvate
2 x net ATP
2 x reduced NAD

Question 3

What are the steps of the Link Reaction? And what are the products?

Answer 3

2 x Pyruvate (from glycolysis) + CoA
>
2 x Acetyl Co. A (2C)

Produced:
2 x Acetyl Co. A
2 x CO2
2 x reduced NAD

Question 4

What are the steps of the Krebs Cycle? And what are the products?

Answer 4

2x
4C + Acetyl Co. A (2C) -> 6C -> 4C

Produced:
4 x CO2
2 x ATP
6 x reduced NAD
2 x reduced FAD

Question 5

Where in the mitochondria does the link reaction occur?

Answer 5

The matrix
