1

What is aerobic respiration?

When an organism releases energy from glucose by reacting it with oxygen.

2

Why do humans need energy?

To keep warm
To move
To grow
To keep the body functioning

3

Where does the glucose that humans use in respiration come from?

Food (carbohydrates)

4

What is the word equation for aerobic respiration?

Glucose + Oxygen --> Carbon Dioxide + Water + Energy

5

How do our bodies get the oxygen needed for aerobic respiration?

We breathe in oxygen from the air

6

What are the 'waste products' of aerobic respiration?

Carbon dioxide + water

7

How are the waste products of aerobic respiration removed from the body?

Carbon dioxide + Water are breathed out

8

What are the reactants of aerobic respiration?

Glucose + Oxygen

9

What are the products of respiration?

Carbon Dioxide + Water + Energy

10

Where does aerobic respiration happen?

Within the mitochondria of cells

11

One single mitochondria is called a

mitochondrion

12

Many mitochondrion are called

mitochondria

13

Muscle cells carry out lots of aerobic respiration. Therefore they contain many...

mitochondria

14

Why do muscle cells use a lot of energy?

Because they contract and expand (move)

15

Glucose is a...

carbohydrate

16

How does glucose get into cells.

1. Carbohydrate is eaten
2. Carbohydrate is broken down into glucose in the small intestine.
3. Glucose is absorbed into the blood plasma.
4. Glucose exits the blood and enters the body's cells.

17

What is blood plasma?

The straw-coloured liquid that red blood cells travel in.

18

How does get into cells?

1. Oxygen is breathed into lungs.
2. Oxygen passes from lungs into the blood.
3. Oxygen is carried by red blood cells
4. When the red blood cell goes near a cell that needs oxygen the oxygen leaves the red blood cell and enters the new cell.

19

Which substance makes red blood cells red?

Haemoglobin

20

What is the function of haemoglobin in red blood cells?

Oxygen sticks to the haemoglobin which allows the red blood cell to carry oxygen around.

21

How does carbon dioxide leave cells?

1. Carbon dioxide exits cell.
2. Carbon dioxide attaches to red blood cells.
3. Red blood cells transport carbon dioxide to the lungs where it is breathed out.
