Question 1

equation for photosynthesis

Answer 1

carbon dioxide + water (light energy) - Oxygen + glucose

Question 2

Where does photosynthesis occur ?

Answer 2

Photosynthesis takes place in the plants leaves.
Chlorophyll absorbs the light energy from the sun.
This light energy is turn into chemical energy, (using the equation for photosynthesis, carbon dioxide and water) and is stored in sugars. This creates glucose and a waste product (oxygen)

Question 3

equation for aerobic respiration

Answer 3

oxygen + glucose - carbon dioxide + water

Question 4

equation for anaerobic respiration

Answer 4

glucose - lactic acid

Question 5

what is anaerobic respiration

Answer 5

anaerobic respiration is when your body is lacking oxygen so uses respiration without oxygen but with only glucose, creating lactic acid

Question 6

when is anaerobic respiration used ?

Answer 6

It is only used in an emergency e.g. during exercise

Question 7

equation for anaerobic respiration in plants and yeast

Answer 7

glucose - ethanol + carbon dioxide + energy
