Questions & Step-by-Step Solutions
What effect does an allosteric activator have on enzyme activity?
Step 1: Understand what an enzyme is. An enzyme is a protein that helps speed up chemical reactions in the body.
Step 2: Learn about substrates. A substrate is the molecule that an enzyme acts on to help create a product.
Step 3: Know what an allosteric activator is. An allosteric activator is a molecule that binds to an enzyme at a site different from the active site.
Step 4: Recognize the role of the active site. The active site is where the substrate binds to the enzyme.
Step 5: Understand how allosteric activators work. When an allosteric activator binds to the enzyme, it changes the shape of the enzyme.
Step 6: See the effect of the shape change. This shape change makes it easier for the substrate to bind to the active site.
Step 7: Conclude that an allosteric activator increases enzyme activity. By enhancing the enzyme's ability to bind to its substrate, the reaction happens faster.
