AS Level Applied Science, RESPIRATION.

Aerobic Respiration...

Gluecose + Oxygen = Carbon Dioxide + Water + Energy.

C6 H12 O6 + O2 = Co2 + H2o + Energy.

Oxygen and gluecose react together in your body to produce energy, this proccess is called respiration. Carbon dioxide and water are produced as by-products of respiration.

When gluecose reacts with oxygen energy is release. Carbon Dioxide and water are formed as waste products, the proccess is known as aerobic respiration because it uses oxygen from the air.

SO... Aerobic Respiration uses oxygen and produces 32 molecules of ATP, with a waste product of carbon dioxide and water!

Anaerobic Respiration...

Gluecose = Lactic acid + (some) Energy.

Anaerobic respiration can only be used for short periods of time because the waste product is harmful (Lactic acid) and not enough energy is made.

Lactic acid soaks the muscle and stops it from doing it's job, So if anaerobic respiration was used constantly it would mean death as the body would not be able to cope with the amount of lactic acide produced.

SO... Anaerobic respiration uses gluecose and produces only 2 molecules of ATP, with a waste product of lactic acid!

SO...

Why is respiration so important?

It is important for these basic factors of bodily functions...

GROWTH, SENSITIVITY, NUTRITION, EXCRETION, REPRODUCTION.

Respiration provides the energy in the for form of ATP, these are required for basic human living.

Examples include:

• Muscle contraction
• Movement of sperm cells
• nerve impulse transmission

Adensoine Triphosphate, ATP...

ATP is made by the break down of gluecose in respiration. ATP powers a day to day activity.

ATP - 1 phospahte - ADP

Oxygen Debt...

Anaerobic Respiration keeps our bodies going until we breathe in enough oxygen to perform aerobic respiration. Whilst we are performing anaerobic respiration our bodies are building up a 'debt' of oxygen.
