Question 4

What is anaerobic respiration called in yeast cells

Answer 4

Fermentation

Question 5

What is “oxygen debt”

Answer 5

The amount of oxygen yo ur body need to react with the build up if lactic acid and remove it from the cells.
React to form harmless carbon dioxide and water

Question 6

Equation for photosynthesis

Answer 6

Carbon Dioxide+Water -light->glucose+oxygen

Question 7

Answer 7

> Respiration
Cellulose - strong plant cell walls
Amino Acids - (glucose combines with nitrate ions to make amino acids to make proteins)
Stored as oils or fats in seeds
Stored as starch
