Answer 2

When there is an enough amount of oxygen.

Question 3

What is the word equation for aerobic respiration? What relationship does it have with the one of Photosynthesis?

Answer 3

Glucose + Oxygen -> Carbon Dioxide + water

Question 4

What is the symbol equation for aerobic respiration?

Answer 4

C6H12O6 + 6O2 -> 6CO2 + 6HO (+Oxygen); It is the exact reverse of the equation for photosynthesis

Question 5

WHat does ATP provide the cells with?

Answer 5

It provides the cells with Energy.

Question 6

What is the difference between Aerobic and Anaerobic respiration?

Answer 6

Oxygen: Aerobic requires while anaerobic does not;
Glucose breakdown: Aerobic: complete, Anaerobic: Incomplete;
Produtcs: Aerobic: carbon dioxide & water, Anaerobic: animal cells produce lactic acid, plant cell and yeast: carbon dioxide & ethanol

Question 7

When does Anaerobic respiration take place?

Answer 7

When there is no oxygen available

Question 8

Answer 8

Glucose -> lactic acid

Question 9

What is the word equation for anaerobic respiration happen in plant cells and yeast?

Answer 9

Glucose -> Ethanol + Carbon Dioxide
