1
Q

What control many chemical reactions inside cells?

A

Enzymes.

2
Q

What is respiration?

A

Respiration is the process of releasing energy from the breakdown of glucose, which goes on in every cell.

3
Q

What is aerobic respiration?

A

Respiration using oxygen.

4
Q

What is the word equation for aerobic respiration?

A

Glucose + oxygen –> carbon dioxide + water + energy

5
Q

Inside where do most of the reactions in aerobic respiration take place?

A

Mitochondria

6
Q

Rather than in animal cells, where else does aerobic respiration take place?

A

Plant cells.

7
Q

What is energy released by aerobic respiration used for?

A
  1. To build larger molecules from smaller ones
  2. In animals, to enable muscles to contract
  3. In mammals and birds, to maintain a steady body temperature in colder surroundings.
  4. In plants, to build sugars, nitrates and other nutrients into amino acids, which are then built into proteins.
8
Q

In plants, what is energy released by aerobic respiration used for?

A

Building sugars, nitrates and other nutrients into amino acids, which are then built up into proteins.

9
Q

In mammals and birds (warm-blooded species), what is energy released by aerobic respriation used for?

A

Maintaining a steady body temperature in colder surroundings.

10
Q

What does energy released by aerobic respiration enable muscle to do?

A

Contract

11
Q

What does energy released by aerobic respiratio allow smaller molecules to do?

A

Build larger molecules. (eg: proteins from amino acids)

12
Q

What changes take place during exercise?

A
  1. Heart rate increases.

2. Rate and depth of breathing increases.

13
Q

How does changes that take place during exercises affect the rate of removal of carbon dioxide?

A

These changes increase blood flow to the muscles –> increase supply of sugar and oxygen –> increase the rate of removal of carbon dioxide.

14
Q

What do muscles store glucose as?

A

Glycogen.

15
Q

How is glycogen used during exercise?

A

It can be converted back to glucose for use.
