In the mitochondria

Question 3

What is the equation for anaerobic respiration ?

Answer 3

Question 6

What are 2 uses of energy ?

Answer 6

Growth and movement

Active transport

Question 7

What are the 2 effects of exercise ?

Answer 7

Increased breathing rate and heart rate

Question 8

What is there more of if there is an increase in breathing rate ?

Answer 8

Increased oxygen in

Increased carbon dioxide out

Question 9

What is there more of if there is an increase in heart rate ?

Answer 9

Pumps more oxygenated blood around the body

Need more glucose to muscles

Remove carbon dioxide from muscles

Question 10

What is oxygen debt ?

Answer 10

When you exercise for a long time or exercise hard you respirate anaerobically and therefore lactic acid builds up so extra oxygen is needed to break down lactic acid so you breathe deeper for longer
