Breathing And Exercise

Question 1

How can we release more energy for muscle contraction during exercise

Answer 1

By increasing the rate of respiration

Question 2

How can we increase the rate of respiration

Answer 2

It needs more oxygen and glucose arriving at the cell. The glucose and oxygen arrive at the cells quicker that means and the heart rate will increase and pump the blood around the body faster

Question 3

What is the result of having more respiration

Answer 3

ATP is provided and muscles can contract easier

Question 4

What does oxygen do to increase the rate of respiration

Answer 4

It increases the breathing rate

Question 5

Independant variable

Answer 5

The variables that change throughout the experiment

Question 6

Dependant variable

Answer 6

What you are measuring

Question 7

How does exercise affect your breathing rate

Answer 7

It needs more respiration, meaning more oxygen would be needed which increases the breathing rate and more carbon dioxide would be produced

Question 8

What happens to your breathing rate straight after exercise

Answer 8

It increases because your body needs more oxygen in your blood
