Oxygen debt

Question 1

Describe what happens in anaerobic respiration with an oxygen deficancy

Answer 1

pyruvic acid forms and reacts to from lactic acid

Accumulates as an end product of anaerobic respiration in the form of lactate

Question 2

What do lactate do during diffusion?

Answer 2

Diffuse out of muscle cells and is carried in the bloodstream in the liver

Question 3

What energy does lactate use in the liver?

Answer 3

Uses ATP, liver cells convert lactate back into glucose

Question 4

What happens to o2 during strenuous exercise

Answer 4

O2 is used to produce ATP for muscle contraction, rather than for converting lactase back to glucose

Question 5

What developed as lactate builds up?

Answer 5

An oxygen debt- must be repaid

Question 6

What does o2 debt refer to?

Answer 6

amount of o2 that liver cells require to convert lactate back into glucose plus muscle cells need to resynthesize ATP

Question 7

What does physical training help?

Answer 7

Increase a muscle capacity to improve energy production
