For our second piece of biology coursework, we had to how be respiration changes as we do exercise.

Respiration is a reaction that takes place in every cell in life and it is how every cell is able to get its energy. ATP is the energy that is used and produced by all cells and cells use it for lots of different tasks.

The energy can be used to actively transport, through absorption against a concentration gradient, material across membranes.

There are two types of useful respiration that we plan to investigate, aerobic and also anaerobic. Most respiration that takes place is aerobic because the energy is more constantly produced.

Aerobic respiration is the release of energy from the breakdown of glucose, by combining it with oxygen inside living cells (the energy is actually contained inside glucose molecules)

Aerobic respiration is a ver y efficient method of producing energy; one molecule of glucose can provide twenty times as much energy as anaerobic respiration.

It occurs during normal day to day activity and accounts for our energy production up to 60% of maximum effort.

Also the draw back is that it doesn’t produce energy anything like as quickly as anaerobic respiration.

Aerobic respiration takes place in the mitochondria of the cells; therefore cells with more mitochondria fast respiring cells like muscle cells.

Mitochondria are found in greater numbers in fast respiring cells because they are the sites of aerobic respiration. They absorb glucose and oxygen and provide energy, which is transferred in cells.

Anaerobic respiration is the release of a little bit of energy, very quick inside living cells, from the incomplete breakdown of glucose in the absence oxygen or oxygen dept.

Because anaerobic respiration involves the incomplete breakdown of glucose, much less energy is released, that in the aerobic respiration.  However it can produce energy much faster over a short period of time until fatigue sets ...
