[Answer] how does pH affect enzyme activity?

Answer: a. changes shape of enzyme by interacting with noncovalent bondsb. also changes shape or charge properties of the substrate sothat either the substrate cannot bind to the active site or it cannot undergo catalysisc. As pH increases enzyme activity increases until it reaches an optimal point in which enzymes denatures and as pH increases enzyme activity decreases.
how does pH affect enzyme activity?

Several factors effect the assay outcome and a recent review summarizes the various parameters that needs to be monitored to keep an assay up and running. • Salt Concentration: Most enzymes cannot tolerate extremely high salt concentrations. The ions interfere with the weak ionic bonds of proteins. Typical enzymes are active in salt concentrations of 1-500 mM. As usual there are exceptions such as the halophilic algae and bacteria.

Protein denaturation due to pH Denaturation can also be caused by changes in the pH which can affect the chemistry of the amino acids and their residues. The ionizable groups in amino acids are able to become ionized when changes in pH occur. A pH change to more acidic or more basic conditions can …

An immobilized enzyme is an enzyme attached to an inert insoluble material—such as calcium alginate (produced by reacting a mixture of sodium alginate solution and enzyme solution with calcium chloride).This can provide increased resistance to changes in conditions such as pH or temperature.It also lets enzymes be held in place throughout the reaction following which they are easily …

Phenylalanine hydroxylase (PAH) (EC 1.14.16.1) is an enzyme that catalyzes the hydroxylation of the aromatic side-chain of phenylalanine to generate tyrosine. PAH is one of three members of the biopterin -dependent aromatic amino acid hydroxylases a class of mo…
