Enzymology, Catalytic Mechanism, Carbohydrate Metabolism, Adenosine Triphosphate
Enzymes are proteins and their function is to act as catalysts to speed up certain chemical reactions in the cell that would be slower without them. This process occurs as steps in a cycle with separate reactions in each step. If there is a missing product the step in the cycle will be incomplete and the normal function of the organism cannot be accomplished causing negative effects on the organism. The biological processed of the body would occur much more slowly or possibly not at all without the presents of enzyme reactions.
Enzymes have some very specific qualities. Enzymes are sensitive to temperature and they tend to work faster as temperature increases, but they can stop working if the temperature becomes too high. Enzymes are also sensitive to pH and their ability to function will be affected if the environment is too acidic or basic for a specific enzyme. Certain chemicals can hinder an enzyme and prevent it from functioning. The inhibition of these enzymes can be temporary or permanent. Enzyme-catalyzed reactions can work both ways or are reversible.
Fructose, a monosaccharide or simple sugar found in fruits, fruit juices and sweeteners such as honey and contains 6 carbons, is broken down by an enzymatic reaction. Fructose is a carbohydrate and is a good source of energy for the body, but it needs to be broken down by enzymes to become energy that can be used by the body. When fructose is consumed the first step begins with the enzyme fructokinase binding with the fructose which produces fructose-1-phosphate. The second step of the cycle takes place when the enzyme aldolase B splits the fructose-1-phosphate into 2 three carbon molecules - DHAP (dihydroxyacetone phosphate) and glyceraldehyde. At this point these two products can enter glycolysis and produce energy for the body to use.
Activation energy is the minimum amount of energy needed for a
