To form chlorophyll with magnesium

Question 4

What are the laws of limiting factors ?

Answer 4

When the rate of a process is affected by multiple factors one of the factors needs to be in short supply

Question 5

Reasons why Greenhouses are used by Framers ?

Answer 5

1) Creates are perfect condition for the plants
2) Protects the plants from animals and the winter
3) Made of glass which allows light to go through
4) Helps photosynthesis take place

Question 6

What are the disadvantages of greenhouses ?

Answer 6

1) Expensive

2) Can import products

Question 7

What is aerobic respiration ?

Answer 7

Respiration is a series of reactions in which energy is released from glucose. Aerobic respiration is the form of respiration which uses oxygen. It can be summarised by this equation:

Question 8

What is the word equation for Aerobic respiration ?

Answer 8

glucose + oxygen → carbon dioxide + water (+ energy)

Question 9

What are the three most important uses for energy in the body ?

Answer 9

1) Active transport
2) Movement
3) Cell Division

Question 10

What is the order of how Glucose gets into your body ?

Answer 10

1) Eat Carbohydrate
2) Digested by the digestive system
3) The small intestine absorbs the Glucose
4) Diffuses into plasma in the blood stream
5) Blood transports the plasma around the body
6) Diffuses into cells

Question 11

How do you get oxygen into the body ?

Answer 11

1) Goes through the main breathing passages
2) diaphragm contracts and pulls air into the lungs
3) Oxygen diffuses from alveoli into the blood
4) Blood transports oxygen sing haemoglobin in red blood cells
5) Diffuses into muscles

Question 12

What is the balanced symbol equation for aerobic respiration ?

Answer 12

C6H12O6 + 6O2 → 6CO2 + 6H2O

Question 13

What is mitochondria

Answer 13

Mitochondria are structures in cells where respiration happens

Question 14

What is anaerobic respiration

Answer 14

Anaerobic respiration is a type of respiration that does not use oxygen. It is used when there is not enough oxygen for aerobic respiration. It can be summarised by the following equation:

Question 15

What is the equation for anaerobic respiration

Answer 15

glucose → lactic acid (+ energy released)
