What is the optimum pH and optimum temperature for enzymatic action?

So, the correct option is ’20-25o C and 7.0 pH’

What happens when an enzyme reaches its optimum temperature?

At the optimum temperature, the kinetic energy in the substrate and enzyme molecules is ideal for the maximum number of collisions. At high temperatures the shape of the enzyme is altered so that it is no longer complementary to its specific substrate.

What is the optimum pH and temperature for enzymes in the human body?

Enzymes in the stomach, such as pepsin ( which digests protein ), work best in very acid conditions ( pH 1 – 2 ), but most enzymes in the body work best close to pH 7.

What can you do to regain the activity of the enzyme?

What can you do to regain the activity of the enzyme? Removing the irreversible inhibitor should get the reaction working again. The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity.

How do enzymes help to speed up chemical reactions?

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

What if an enzyme in your body stops working?

When an enzyme stops working we call it “denatured.” Here are some things that can affect enzyme activity: Temperature – The temperature can affect the reaction rate. The higher the temperature, the faster the reaction will occur.

What is the optimal pH that this enzyme functions at?

It has an optimum pH of about 1.5. On the other hand, trypsin works in the small intestine, parts of which have a pH of around 7.5. Trypsin’s optimum pH is about 8….10.7: The Effect of pH on Enzyme Kinetics.

Enzyme Lipase (stomach)
Optimal pH 4.0 – 5.0
Enzyme Maltase
Optimal pH 6.1 – 6.8

Is there an optimum temperature for catalase that makes it the most productive in terms of reaction rate?

Optimal temperature for catalase activity is around 30’C because the highest amount of oxygen bubbles were observed at this temperature. Catalase activity decreases after optimal temperature. This happens because the enzyme becomes denatured. Denaturing is when an enzyme loses its shape at the active site.
