Factors
affecting the enzyme's reaction rates
|
| |
|
| |
Introduction:
Enzymes play
many important roles in our body and have many
industrial applications as well. One role of enzymes in
our body is digesting different foods. For example Lactase
is the enzyme in the small intestine that digests
lactose (the naturally occurring sugar in milk), and
Amylase is an enzyme that digests starch. |
 |
Because of the importance of
enzyme activity in different chemical and biochemical reactions,
it is important to know the factors that affect the enzyme
activity rate.

Project
description:
In this project you study
the effect of enzyme concentration, temperature and pH on the
rate of enzymes activity. As you see this is a 3 in one
project. Each of the following three questions can be the
subject of a project.
- How does pH affect the
activity of the enzyme?
- How does temperature affect
the activity of the enzyme?
- How does enzyme
concentration affect the rate of a reaction involving a
specific enzyme as a catalyst?
It takes about one day to
complete your experiments and record your results. You will need
to perform a chemical reaction involving enzymes and measure the
rate of production.
