Respiration is the process of releasing energy from glucose, which happens in every
This energy is used to do things like:
Builds up larger molecules (like proteins)
Maintain a steady body temperature.
There are two types of respiration: Aerobic and Anaerobic
Aerobic respiration needs plenty of oxygen.
It releases more energy per glucose molecule than anaerobic.
Glucose + Oxygen Carbon dioxide + Water (+Energy released)
Energy releases in respiration is used to make ATP ATP is a small molecule that's
easily transported around the cells. It carries the energy released during respiration
to the places where the energy is needed in the body. Energy released from both
types of respiration is used to produce ATP. ATP is the energy currency of living
1. ATP is synthesised from another molecule called ADP using the energy
released by the breakdown of glucose during respiration.
2. ATP moves to the part of the cell that requires energy.
3. It's then broken down to ADP and this releases energy where it's needed.

Anaerobic exercise doesn't used oxygen at all
When you do really vigorous exercise your body can't supply enough oxygen to our
muscles for aerobic respiration so your muscles have to start respiring
anaerobically. In this form of respiration the glucose produces lactic acid because it
is only partially broken down.
Glucose Lactic Acid (+Energy released)
The lactic acid builds up in the muscles after resorting to the anaerobic respiration,
when you stop exercising you'll have oxygen debt.…read more
