Summary Introduction

To explain:

The substance that can be added to the reaction mixture to maintain a high activity of the enzyme, with the reason for the same.

Introduction:

The acidic or basic character is expressed in terms of pH (potential of hydrogen). It is a negative logarithm of the concentration of H+. A solution is neutral if its pH is 7, basic if it is greater than 7, and acidic if it is less than 7. The maintenance of pH is critical to living organisms because changes in pH bring about changes in the ionic states of biomolecules.

enzymes are naturally occurring catalysts responsible for various biochemical reactions. Give a modern and recent application of an enzyme used in a biochemical reaction a - the commercial or trade name of the catalyst and enzyme. b - the properties of the catalyst and enzyme (e.g., shape, size, colour, price). c - the advantages and the disadvantages of the chosen catalyst and enzyme d - catalytic reaction (e.g., the reactant, product, reaction equation, phase, selectivity, promoter, catalyst support, operating temperature & pressure).
Imagine you are working in a lab, and you are performing two chemical reactions. You notice that Reaction A occurs much faster than Reaction B, and that both reactions release the same amount of heat. Which of the following conclusions can be made from your observation? Reaction A has the same activation energy as Reaction B, and the AG of Reaction A is more negative (i.e., a larger negative number) than the AG for Reaction B. Reaction A has a lower activation energy than Reaction B, and the AG of Reaction A is the same as the AG of Reaction B. Reaction A has a higher activation energy than Reaction B, and the AG of Reaction A is the same as the AG of Reaction B. Reaction A has the same activation energy as Reaction B, and the AG of Reaction A is less negative (i.e., a smaller negative number) than the AG for Reaction B.
Enzyme kinetics uses math to quantify all of the following, except: a. An enzyme's substrate affinity b. None; all the other choices are correct OC. An enzyme's catalytic power Od. An enzyme's stability
