Question

11. If resting RER increases to 0.88, how are contributions from carbohydrates and fats to the resting metabolism altered?

1. CHO contributions increase/fat contributions decrease
2. CHO contributions decrease/fat contributions increase
3. no change in contributions from CHO or fats because you are at rest.

12. This enzyme breaks down triglycerides to form glycerol and fatty acids.

1. citrate synthase
2. phosphofructokinase
3. phosphorylase
4. hormone-sensitive lipase

13. _______True/False: During high-intensity anaerobic exercise, fat utilization increases.

Answer 1

Solution

Ans:-11) correct option is a) contribution of CHO increases / fat contribution decreases.

RER :- respiratory exchange ratio

It is the ratio between amount of CO2 produced in an metabolism to the amount of O2 used.

When resting RER is

• At 0.70 - fat is predominant fuel
• At 0.85 - mix fat and carbohydrates are fuel
• At 1 - suggest carbohydrates is predominant fuel.

Ans-12) d) hormone sensitive lipase ( pancreatic lipase)

Is responsible for break down of triglycerides into glycerol and fatty acids.

Ans-13) True

During high density anaerobic exercise the use of CHO , and fats increases
