Increase In Breathing/Heart Rate

Question 1

What is the effect of mild exercise on your breathing rate?

Answer 1

The breathing rate increases meaning more oxygen produces more energy through aerobic respiration allowing your muscles to contract.

Question 2

What is the effect of mild exercise on your heart rate?

Answer 2

The heart rate increases meaning more oxygen and glucose are transported in your blood to produce more energy through aerobic respiration allowing your muscles to contract?

Question 3

What are the 3 steps in the effect of vigorous exercise?

Answer 3

1. If the body cannot supply enough oxygen to muscles using aerobic respiration it switches to anaerobic respiration.
2. Anaerobic respiration releases less energy as it doesn’t completely break down glucose meaning lactic acid is produced.
3. Oxygen debt is created which either broken down by oxygen producing carbon dioxide. Or it transported to the liver where it is converted back into glucose.
