Question 2

What is the dominant contribution once steady state has been achieved?

Answer 2

Oxidative Phosphorylation

Question 3

Answer 4

Carbohydrate

Question 5

What is stoichiometry?

Answer 5

Amount of substances involved in reactions

Question 6

In stoichiometry, if RER= 1, what can we conclude?

Answer 6

The participant is exclusively utilising carbohydrate

Question 7

When exercise intensity intensifies, why do we have a greater reliance in muscle glycogen and a reduction in free fatty acids?

Answer 7

CPT 1 Protein

Question 8

What does the CPT 1 Protein do?

Answer 8

Regulates the transport of fatty acids into the mitochondrial DNA
