Q

Why does aerobic respiration release a great amount of energy?

A

Because the glucose molecule has been fully oxidised.

Q

What is anaerobic respiration?

A

anaerobic respiration does not need oxygen. It is the release of a relatively small amount of energy in cells.

Q

Why is the energy in anaerobic respiration low?

A

Because the glucose molecule has not been fully broken down yet meaning that it transfers much less energy.

Q

How is fermentation used to make bread?

A

This is because the carbon dioxide produced creates bubbles in the dough causing it to rise.

Q

What happens to our body during exercise?

A

The body needs a great deal of energy for muscle contraction.

17
Q

How does our body provide more oxygen during exercise?

A

Our heart rate, breathing rate and breath volume all increase. We breathe more frequently and take deeper breaths.

18
Q

What respiration do we use during heavy exercise?

A

Anaerobic respiration.

19
Q

What does the use of anaerobic respiration cause?

A

Lactic acid build-up and oxygen debt.

20
Q

What does lactic acid do to our muscles?

A

It causes them to hurt and stops them from contracting efficiently.

21
Q

What happens after exercise?

A

We still are out of breath as the oxygen debt is being repaid.

22
Q

What happens to the latic acid in our body?

A

Blood flowing through the muscle transports the lactic acid to the liver where it is broken down.

23
Q

What is the oxygen debt?

A

It is the amount of extra oxygen the body needs after exercise to react with the lactic acid and remove it from the cells.
