Answer 2

3-15 seconds
100 m

Question 3

How long is the lactate system
give an example

Answer 3

15-90 seconds
400 m

Question 4

How long is the aerobic system
give an example

Answer 4

90- …
marathon

Question 5

What does atp do?

Answer 5

It is a molecule that stores & releases energy for muscle contraction

Question 6

How is adp formed

Answer 6

When a cell needs energy it breaks the bond to form adp & an extra posphate molecule

Question 7

What does atp-pc stand for

Answer 7

Adenosine triphosphate - phosphocreatine

Question 8

What does the body break down

Answer 8

carbohydrates into glucose

Question 9

Where is any excess stored

Answer 9

in the liver as glycogen

Question 10

How is ATP in the lactate system made

Answer 10

By the partial breakdown of glucose & glycogen through anaerobic glycolysis

Question 11

How many molecules of ATP are produces by glucose

Answer 11

two molecules

Question 12

How many molecules of ATP are produces by glycogen

Answer 12

three molecules

Question 13

What is a by product of anaerobic glycolysis

Answer 13

pyruvic acid= lactic acid

Question 14

What is stage 1

Answer 14

aerobic glycolysis

Question 15

What is stage 2

Answer 15

krebs cycle

Question 16

What is stage 3

Answer 16

electron transport chain

Question 17

What happens in stage 1

Answer 17

Glucose is converted into pyruvic acid using oxygen

Question 18

What happens in stage 2

Answer 18

The pyruvic acid gets converted into citric acid. Co2 and hydrogen are produced as by products

Question 19

How many molecules of ATP are produced in the three stages

Answer 19

2
