Explains what is meant by enzyme activity and the factors that impact on their ability to function. Looks at temperature, pH value, substrate concentration, enzyme concentration, the presence of inhibitors, and allosteric factors that...

Explains what enzymes are, the three broad categories, their working mechanism and two theories developed to explain this, and factors that impact enzyme activity.

Every enzyme has an optimal pH value at which it functions best. This article explains why pH has an effect on enzyme activity and how it affects them.

This is a basic project on the effect of enzymes on apple slices. The goal of the project is to monitor enzyme activity by measuring the amount of apple juice released by pectinase.

This lesson will identify the structure and function of enzymes.

Sometimes science can be really messy or use pretty disgusting ingredients. That is what it takes to understand how the world works, even if the experiment isn't pretty. If you like chemical reactions that stink and ooze foamy bubbles...

Pizza, milk shakes, and ice cream sundaes all contain dairy products, therefore they cannot be eaten by the majority of people around the world. Dairy products contain the sugar molecule lactose, and the majority of people on the planet...

Experiment with factors that affect the activity of the weed killer Roundup. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms, concepts, and...
