Aerobic Respiration
Respiration that requires oxygen
For all cells to carry out their processes, they require
energy to function (this relates to all living organisms).
Respiration in general is the release of energy from
food molecules that acts as fuel for the cell.
The word equation for Aerobic Respiration:
glucose + oxygen carbon dioxide + water
In Aerobic Respiration, the glucose and oxygen are
converted into water and carbon dioxide, and the
energy for use in the cell.
All the substances (carbon dioxide, oxygen and
glucose) are moved between the capillaries and the
respiring cells.
The process that does this, is called DIFFUSION
The glucose and oxygen needed for respiration are
carried by blood around the body and into tissues.
DIFFUSION IS THE MOVEMENT OF NET PARTICLES
FROM AN AREA OF HIGHER CONCENTRATION, TO AN
AREA OF LOWER CONCENTRATION.

Capillaries are tiny blood vessels.
Glucose and Oxygen levels decrease as they are used
in Aerobic Respiration, whereas Carbon Dioxide rises.
What is Gas exchange?
The process that takes place in the lungs in which
oxygen diffuses from the lungs and into the blood.
However, carbon dioxide diffuses from the blood
into the lungs.
Gas Exchange
Lung tissues are spongy and are full of tiny air sacs
called alveoli.…read more
