Respiration

Question 1

What’s the equation for aerobic respiration

Answer 1

Glucose + oxygen —> carbon dioxide + water

Question 2

Why is ATP a good store of energy

Answer 2

1) released in small manageable amounts
2) quick release of energy
3) simple singe, reversible reaction
4) soluble

Question 3

What are the 4 stages of respiration

Answer 3

Glycolysis
Link reaction
Krebs cycle
Oxidative phosphorylation/ ETC

Question 4

What is the location and function of glycolysis

Answer 4

Inside the cytoplasm and to produce pyruvate from glucose so it can enter the mitochondria

Question 5

What are the reactants and products of glycolysis

Answer 5

Reactants:
Glucose, ATP, NAD, ADP+Pi

Products:
Pyruvate, reduced NAD, ATP

Question 6

What is the location and function of the link reaction

Answer 6

Inside the mitochondrial matrix and to produce acetal coenzyme A which can enter the Krebs cycle, and to produce reduced NAD

Question 7

What are the reactants and products of the link reaction

Answer 7

Reactants:
Pyruvate, coenzyme A, NAD

Products:
Acetyl CoA, reduced NAD, CO2

Question 8

What is the location and function of the Krebs cycle

Answer 8

Inside the mitochondrial matrix, and to produce ATP and reduced NAD, in substrate level phosphorylation

Question 9

What is the definition of substrate level phosphorylation

Answer 9

Direct transfer of Pi to ADP from intermediates to form ATP

Question 10

What are the reactants and products of the Krebs cycle

Answer 10

Reactants:
Acetyl CoA, NAD, FAD, ADP+Pi

Products:
ATP, reduced NAD & FAD, CO2, Coenzyme A which is recycled to the link reaction

Question 11

What is the location and function of the electron transport chain

Answer 11

Inside the inner mitochondrial membrane and is to release lots of ATP and regenerate NAD and FAD
