Introductio n and Summary Dear readers: I trimmed this essay down to reflect that the essay delves far deeper into many issues that this essay originally covered. My original energy essay was written aroundand could be considered the embryonic version of the version. If early humans did not learn to exploit new sources of energy, humankind would still be living with its ape cousins in the tropical forests.

This is known as fermentation and is explained using the following equation: The enzymes produced by the yeast will only catalyse the fermentation of certain carbohydrates but not others.

Moreover, different Two carbohydrate solution essay of yeast produce different enzymes. Enzymes work using the enzyme-substrate complex.

That is, the substrate becomes attached to the enzyme using the active site of the enzyme using the lock and key theory.

This allows the substrate and the enzyme to interact in a specific way leading to a chemical reaction involving the substrate to take place and appropriate products will be formed. Enzymes are highly specific and so they have the ability to distinguish between pairs of optical isomers and this is important in this case.

A close match between the structure of the substrates and the outline of the active site helps achieve this. However, enzymes are proteins and since proteins are not rigid, some enzymes are able to fold around their substrate after the initial binding.

The two most important substances that one must consider in relation with this study are zymase and co-zymase, that are both found in yeast.

These enzymes will be used by the carbohydrate substrate to form products such as ethanol and Carbon Dioxide. Along with zymase, co-zymase has to present and this is required to catalyse the reaction successfully. Harden and Young found that on adding yeast juice to a solution of Glucose, fermentation started immediately.

BeforeHans Buchner and Eduard Buchner had carried out many key experiments related to fermentation. The disadvantage with this is that it is much slower than in producing products than glucose. Glucose appears to be a favourite of many scientists who have dealt with fermentation.

For example, the wine industry use glucose as a substrate for zymase to interact, in order to produce the relevant ethanol and Carbon Dioxide. Often to obtain Glucose in industry a series of reactions are carried out using starch. Overall, one cannot state that only Glucose is able to convert into ethanol and Carbon Dioxide, as this is not true.

Other Carbohydrate substrates such as Fructose, Galactose and so on are also capable of this reaction. This is what this study is aiming to prove that Glucose has the most favourable structure for yeast enzymes to work.

Key Factors Affecting the Experiment. Moreover, one must decide which factors to control i. This is a key factor for this experiment, as variations in temperature will directly affect the reaction rate.

If one increases the temperature, they will increase the reaction rate. This is due to the increase in the kinetic energy of the reacting molecules.

Hence, more enzyme-substrate complexes are formed in the same amount and so products will be formed faster. However, since enzymes are involved one has to consider denaturation.A specie is a group of organisms that share the many similar appearances and can bread with each other.

Species are scientifically named by two names in Latin to avoid differences in languages.

de Candolle, who described it as a fibrous, tasteless material, insoluble in water and alcohol but soluble in weak alkaline solutions, and which can be precipitated from solution using acid.

He named the substance “lignine”, which is derived from the Latin word lignum, meaning wood. A stye is a red, inflamed bump on the inside or outside of the eyelid.

The bump is caused by a collection of pus, and a bacterial infection is often responsible. Styes may be painful, but they are.
