Different enzymes work best at different pH. This is refered to as the ideal pH for the enzyme.

For example, the digestive enzyme trypsin works best at an acidic pH while alkaline phosphatase works best at a basic pH.

Therefore, enzyme activity varies with pH and this variation depends on the enzyme being studied

What is the effect of starch concentration on amylase activity?

The effect of starch concentration on amylase activity is that increased starch concentration typically enhances enzyme activity up to a certain point. As starch concentration rises, there are more substrate molecules available for amylase to act upon, leading to increased rates of reaction and more glucose production. However, beyond a certain concentration, the enzyme may become saturated, resulting in a plateau in activity where further increases in starch concentration do not significantly affect the rate of reaction. Additionally, factors such as temperature and pH also play a crucial role in enzyme activity.


Chemical reactions occur on the active blank of an enzyme. on a crossword. rest of answers would be nice. Biology crossword?

The chemical reactions occur on the active site of an enzyme. The rest of the answers could include "substrate" for the molecule acted upon by the enzyme, "cofactor" for an additional substance required for enzyme activity, and "inhibitor" for a molecule that reduces enzyme activity.


What effect does the lock and key process have on the enzyme structure?

Easily Explained thusly: When the key is in the lock the Enzyme has one Structure, and when the key is not in the lock the Enzyme has another Structure. Note that the presence of a key may either activate or deactivate an Enzyme, depending upon the conditions.


The substance acted upon by an enzyme is called its?

A substrate is the substance acted upon by an enzyme. The enzyme substrate complex is when an enzyme molecule combines with its substrates.


What is the substance an enzyme act upon called?

the substance that an enzyme acts upon is subtrate


Optimal activity of an enzyme depends upon its Primary structure or Secondary structure or tertiary structure or amino acid sequence or disulphide bridge stability?

Primary structure


What is considered a model for enzyme?

the answer is lock and key model .


A specific reactant an enzyme acts upon is called the a catalyst b sucrase c active site d substrate?

D. substrate (a specific reactant acted upon by an enzyme is called the enzyme's substrate.)


Did lactase activity depend upon the presence of cofactors?

Yes, lactase activity depends on the presence of cofactors such as magnesium and zinc ions to function optimally. These cofactors help stabilize the enzyme structure and facilitate the breakdown of lactose into glucose and galactose. Without these cofactors, lactase activity may be reduced.


Substance that enzyme act upon?

Enzymes act upon specific molecules called substrates. Each enzyme has a unique shape that allows it to bind to a specific substrate, facilitating a chemical reaction to occur. This specific binding of enzyme to substrate is key to the enzyme's ability to catalyze reactions in living organisms.


What is the enzyme called that acts upon the substrate pepsin?

The enzyme that acts upon the substrate pepsin is also called pepsin. Pepsin is a digestive enzyme produced in the stomach that helps break down proteins into smaller peptides.


Specific reactant an enzyme acts upon is?

substrate
