Anaerobic respiration of Yeast:
Effect of concentration
The aim of this project is to find the effect of glucose concentration in the anaerobic respiration of yeast. It may increase, decrease or not even affect the rate of reaction in respiration.
Hypothesis: The expected result is that as the higher the concentration, the faster the reaction will take place.
The purpose of respiration is to break down food into inorganic matter in order to obtain energy. Every cell in the living organism needs energy in order to work, and so without the process of respiration we would die. Sugar is a food often used for respiration, and it needs oxygen to be oxidized and release the energy stored in the chemical bonds. However, there are two different types of respiration. The aerobic respiration, used more commonly, depends on the use of oxygen and can be summarized like shown below. The sugar most commonly used is glucose.
Sugar + oxygen carbon dioxide + water + energy
C6H12O6 +6O2 6CO2 + 6H2O + energy
However, there is yet another type of respiration, called anaerobic respiration...
