Question

At what ph will the enzyme show 78% of maximal activity?

Answer 1

Answer:

The enzyme shows 78% maximal activity at pH 7.5 and 8. 0

Explanation:

• At pH 5.5 and 6.5 it has lower activity (one tenth more or less). If it mixes this enzyme with another protein, an activity enhancement only at low pH where the enzyme was not fully active. In other words, a protein that is interacting with enzyme and expands the pH spectrum at which the enzyme is fully active.
• The pH need is typical because of the side groups of the amino acids. An alteration in pH changes the protonation design and can, in extreme cases, outcome in protein denaturation. The protein stabilizes the enzyme structure, thus keeping it active at sub optimal pH values.
• Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate cannot bind to the active site or it cannot undergo catalysis.

Answer 2

A recombination enzyme as the highest activity at 7.5- 8 ph. Ph 5.5 -6.5 as the lowest activity. If enzyme is mix with other protein, activity enhancement only at low ph where the enzyme is not fully active. Therefore, protein that is interacting with enzyme and expands the pH spectrum at which enzyme is fully active.
