Question 4

What is transferred to the environment when new bonds are formed?

Answer 4

Energy

Question 5

Aerobic respiration word equation

Answer 5

glucose + oxygen –> carbon dioxide + water

Question 6

Which part of the cell carries out respiration?

Answer 6

Mitochondria

Question 7

Where are mitochondria found?

Answer 7

In animal and plant cells as well as in fungal and algal cells

Question 8

What does the number of mitochondria in a cell tell you about its activeness?

Answer 8

If a cell has a larger amount of mitochondria, the more active the cell is

Answer 11

Increased

Question 12

What happens to heart rate, breathing rate and breath volume during exercise?

Answer 12

Increases

Question 13

Answer 13

Converted to glucose for cellular respiration

Question 14

Does the flow of oxygenated blood increase or decrease during exercise

Answer 14

Increases

Question 15

Anaerobic respiration word equation

Answer 15

glucose –> lactic acid

Question 16

State the three main uses of the energy transferred in your body during aerobic respiration

Answer 16

growth movement and constant temperature

Question 17

What is oxygen dept?

Answer 17

The amount of oxygen to remove the build up of lactic acid in the muscles

Question 18

Anaerobic respiration in other organisms word equation

Answer 18

glucose –> ethanol + carbon dioxide

Question 19

Why do we respire anaerobically?

Answer 19

If muscles work hard for a long time they become fatigued and don’t contract efficiently. if there is not enough oxygen
