Respiration
● Respiration is a chemical reaction that happens in every single cell and it is
make to obtain energy.
● All living cells are made up of chemical substances
● The processes of living involve reactions between the substances
● A reaction is an event which produces a change in a substance
● By this event we get energy.
● One of the energy-producing reactions is called respiration
(Respiration is not the same thing as breathing)
● The reaction takes place between oxygen (from the air or water) and a
substance which contains carbon (food). The reaction produces carbon dioxide
and water, and releases energy. The energy is used to drive other chemical
reactions taking place in cells
● One example of an energy-producing reaction in cells is the breakdown of
sugar when it combines with oxygen.
Aerobic Respiration
● The process of respiration described so far has been defined as the release of
energy when foodstuffs such as glucose react with oxygen to produce carbon
dioxide and water.
● This form of respiration, which needs oxygen, is called aerobic respiration.
● Word and chemical equation
, ● Energy use in muscle contraction: The blood stream brings food and oxygen
to the muscle cells. Respiration occurs in the cells and releases energy which
makes the muscle contract and pull the lower arm up.
Anaerobic respiration
● There is another form of respiration which does not need oxygen and is
called anaerobic respiration.
● In anaerobic respiration, glucose is still broken down to carbon dioxide with
the release of energy, but without the involvement of oxygen.
● The glucose is not completely broken down to CO2 and H2O but to CO2
and alcohol (ethanol).
● Anaerobic respiration can be represented by the equation 8
