whatdo enzymes do for us? what is the optimum of an enzyme mean?
Homework Answers
enzymes are biocatalyst which enhance rate of reaction with out taking active part in main reaction.
enzymes catalyze reaction in our body and carry out in very lower energy. enzymes decrease activation energy of reaction. if enzymes are not present in body then it will take too much time and energy to carry out daily metabolic process. in body as wel as enzymes are used in daily life also like in detergents, food processing, medicines etc to gives better results.
enzymes are mode up of complex structure of protein and in proteins are stable then enzymes will gives better response.
so that for optimum rate of reaction enzymes need optimum pH, temperature, as well as concentration of inorganic cofactor, ions etc. which stabilize protein structure of enzyme.

Enzymes Temperature is an important factor that can regulate enzyme-mediated functions. Temperature is one of the tightly homeostatically controlled variables in the human body. What are the symptoms of loss of temperature control during a high fever? Explain why these symptoms occur based on enzyme function and cell signaling effects that are dependent on temperature. Based on Figure 1, explain how the temperature optimum of the activity of enzymes is expected to differ in organisms depending on where they live....

Why do restriction enzymes need to be kept on ice? What order should the DNA, enzyme, water and buffer be added to the microcentrifuge tube for a restriction digest? If lambda DNA is linear, how many times would the enzyme have to cut the DNA to generate five DNA fragments? Would a shorter DNA fragment move faster or slower through the agarose gel than a longer fragment? Why?
