ATP- Respiration

Question 1

Glycolysis- WHAT IS THE ULTIMATE product of the phosphorylation part of glycolysis?

Answer 1

Hexose Bisphosphate

Question 2

In which part of glycolysis is ATP used?

Answer 2

Phosphorylation

Question 3

What form of reaction breaks down hexose bisphosphate to triose phosphate?

Answer 3

Hydrolysis

Question 4

What are the by-products created in the oxidation of triose phosphate to pyruvate?

Answer 4

4ATP, 2NADH, 2H+

Question 5

What is the end product of Glycolysis?

Answer 5

2 Pyruvate

Question 6

Which stages of oxidation are reduction or oxidation?

Answer 6

NAD+ - NADH = Reduction

Triose phosphate - Pyruvate = Oxidation

Question 7

What is the net gain of ATP in Glycolysis?

Answer 7

2ATP

Question 8

Link reaction- What is the ultimate product of the link reaction?

Answer 8

Acetyl CoA

Question 9

What are the steps taken from pyruvate to Acetyl CoA?

Answer 9

1) cO2 given off, decarboxylation
2) NAD+ -> NADH (allows 2C molecules to be oxidised)
3) CoA added
4) Finally forming Acetyl CoA

Question 10

Where do the products of the link reaction go?

Answer 10

2 Acetyl CoA > Krebs Cycle
2 CO2> Waste
2 NADH > ETC

Question 11

Krebs cycle- What are the products for every one turn of the Krebs cycle?

Answer 11

1 Acetyl CoA > 2CO2, 1ATP, 8 pairs of H atoms

Question 12

What is the definition of a Coenzyme?

Answer 12

They are complexed organic molecules used by enzymes to accept or donate molecules in a reaction
