Anaerobic Respiration test

Biogas Generators use up plant and animal waste and the material  left in the generator after can be used as fertiliser.

Yeast is a unicellular organism 

Anaerobic respiration in yeast is called fermentation

Yeast is used to make beer and bread 

Glucose->carbon dioxide+ethanol(+a little energy)

Exercise increases the rate at which energy is needed from food. This increases the need for both food and oxygen in the body. This is why your pulse rate and breathing rate increase with exercise. Your pulse is just an indication of your heart rate as your arteries expand each timethe ventricles pump blood out of the heart. Your heart speeds up to pump extra food and oxygen to the muscles. Breathing speeds up to get more oxygen and to get rid of more carbon dioxide.

When a fit person, such as an athlete, exercises the pulse rate, breathing rate and lactic acid levels rise much less than they do in an unfit person. The time which it takes for pulse and breathing rate to return to normal is called the recovery time, and the fitter you are, the shorter your recovery time.

Not enough oxygen may reach the muscles during exercise. When this happens, they use anaerobic respiration to obtain energy.

Anaerobic respiration involves the incomplete breakdown of glucose. It releases around 5% of the energy released by aerobic respiration, per molecule of glucose. The waste product is lactic acid rather than carbon dioxide and water:

glucose → lactic acid (+ little energy)

Respiration is a series of reactions in which energy is released from glucose. Aerobicrespiration is the form of respiration which uses oxygen. It can be summarised by this equation:

glucose + oxygen → carbon dioxide + water (+ energy)

Muscles become fatigued (tired) during long periods of vigorous activity. This means that they stop contracting efficiently. One cause of this is the build-up of lactic acid in the muscles from anaerobic respiration. The lactic acid is removed from the muscles by blood flowing through them.

Fermentation is the production of ethanol. It occurs when yeast breaks down sugars in the absence of oxygen. Fermentation is used to make alcoholic drinks, such as beer and wine. Carbon dioxide gas is also produced during fermentation.
