Biology - Aerobic and anaerobic respiration

What is aerobic respiration?

It is when oxygen from the air is used to release energy from glucose

What is anaerobic respiration?

It is when respiration takes place and energy is released from glucose without oxygen

What is the word equation for aerobic respiration?

Oxygen + Glucose = Carbon dioxide + water

What is the word equation for anaerobic respiration?

glucose = lactic acid

How many molecules of ATP are released per glucose molecule for aerobic respiration?

Up to 38 ATP molecules can be released

What does ATP mean?

adenosine triphosphate

How many molecules of ATP are released per glucose molecule for anaerobic respiration?

2 ATP molecules

What is the symbol equation for aerobic respiration?

C6H12O6 + 6O2 = 6CO2 +6H20

Where does aerobic respiration take place

Mitochondria

Where does anaerobic respiration take place?

Cytoplasm

Anaerobic respiration equation in yeast

Glucose = Ethanol + Carbon dioxide

What is the equation for anaerobic respiration?

Glucose = Lactic acid + energy

What does anaerobic respiration produce?

- Lactic acid
- Oxygen debt
- Happens for short periods of time

Why does lactic acid need to be broken?

To allow muscles to return to normal

What do both do?

- Produce energy
- Happens in the cell
- Requires glucose

Why is lactic acid poisonous?

It stops muscles from contracting and relaxing, hence they become fatigued
