Factors that affect enzyme activity

In summary, enzymes are proteins that act as catalysts in biochemical reactions, helping to speed up the rate of a reaction without being consumed. Their activity can be affected by factors such as temperature, pH, substrate concentration, enzyme concentration, and the presence of inhibitors. Temperature and pH have optimal levels for enzyme activity, with deviation from these levels leading to denaturation and decreased activity. Substrate concentration can also affect enzyme activity, with an optimal point of saturation where increasing substrate concentration does not further increase activity.

Two graphs are given

But i don't know how to explain each of them?? first one is curved because there is not enough substrate maybe ??

This looks like homework/schoolwork. For such questions, you need to post in the Homework Help forums, and use the Template you are provided there to show the exact problem statement, the relevant equations / concepts, and your attempt at the solution.

If this is for schoolwork, please re-post in the Homework Help forums. If it is for your work, can you please provide more context? Thank you.
 

What is an enzyme?

An enzyme is a type of protein that acts as a catalyst in biochemical reactions. It helps to speed up the rate of a reaction without being consumed in the process.

What are the factors that affect enzyme activity?

Enzyme activity can be affected by various factors such as temperature, pH, substrate concentration, enzyme concentration, and the presence of inhibitors.

How does temperature affect enzyme activity?

Enzymes have an optimal temperature at which they function best. As temperature increases, the rate of enzyme activity also increases until it reaches the optimal temperature. Beyond the optimal temperature, the enzyme structure begins to denature and the activity decreases.

What is the role of pH in enzyme activity?

Enzymes also have an optimal pH at which they function best. Changes in pH can cause the enzyme to denature and lose its shape, affecting its ability to bind to substrates and catalyze reactions.

How does substrate concentration affect enzyme activity?

Increasing the concentration of substrates can increase the rate of enzyme activity up to a certain point. Beyond this point, the enzyme becomes saturated and adding more substrate will not further increase the activity rate.
