Aerobic respiration

Respiration
It is the process of
transferring energy from
glucose to every cell
...
(Ventilation)
It occurs in both plants and
animals
...

(Transfers energy to the
environment0

Aerobic = requires
oxygen
...

It happens all the
time in plants and
animals
...
For winter
...

Energy is transferred to chloroplasts from
the environment by light
...

Only useful in emergencies as it doesn’t transfer as much
energy as aerobic respiration because glucose is not fully
oxidised
...

You have to repay your body back with oxygen
...

The blood entering the muscles transports lactic
acid to the liver where it is converted back to
glucose



Exercise

In yeast cells, anaerobic respiration is called fermentation
...

Carbon dioxide from fermentation makes the bread rise
Ethanol from fermentation makes drinks alcoholic
...
g
...

 More energy = more respiration = more
oxygen
 Breathing rate + breath volume
increases to get more oxygen into blood
 Heart rate increases to get oxygenated
blood around the body
 Vigorous exercise causes anaerobic
respiration to take place as body cannot
supply oxygen
...

 Long periods of exercise causes muscle
fatigue so muscles get tired and stop
efficiently contracting

As distance
increases, light
intensity
decreases
...

 Fertilisers – provides minerals for
healthy growth
 Pesticides – Prevents pests and
diseases
