Chapter 5:Respiration NOT FINISHED

Question 1

what are the 4 stages of respiration?

Answer 1

Glycolysis, link reaction, krebs cycle, oxidative phosphorylation

Question 2

what are the three products of glycolysis?

Answer 2

4 ATP, 2 NADred, 2 pyruvate

Question 3

what happens to 2/4 ATP molecules in glycolysis?

Answer 3

they are used during the phosphorylation of the glucose molecule

Question 4

in glycolisis, what is hexose bisphosphate split into?

Answer 4

2 triose phosphate molecules

Question 5

What are the products of the link reaction?

Answer 5

Acetylcoenzyme A, 1 NADred and 1 CO2

Question 6

In the link reaction, pyruvate uses dehydrogenation and decarboxylation to produce what?

Answer 6

Acetate (2C) - then uses coenzyme A to produce ACETYLCOENZYME A

Question 7

How many times does the kreb cycle happen per glucose molecule?

Answer 7

2

Question 8

Per glucose molecule, how many NADred are produced in the link reaction?

Answer 8

2

Question 9

In the krebs cycle, how does citrate (6C) become a-ketoglutarate?

Answer 9

Oxidised NAD become NADred and decarboxylation, producing one CO2 molecule

Question 10

In the krebs cycle, how does a-ketoglutarate become Oxaloacetate (4C)?

Answer 10

Carboxylation (producing 1 Co2 molecule), NADred x2, 1 ATP molecule produced and 1 FADred
