Question

One molecule of an enzyme is able to catalyse conversion of two molecules of substrate into products in $5$ minutes. Ten molecules of enzyme and $25$ molecules of substrate are mixed in a test tube. At the end of $10$ minutes the test tube will have

• A. Products only
• B. Products and enzymes molecules
• C. Products and $5$ unreacted substrate molecules
• D. Products, enzyme molecules and $5$ molecules of substrate

Answer 1

The correct option is B Products and enzymes molecules

When enzyme reacts and binds with substrate they give products so, in the end of 10 minutes, there will be products and enzymes in the test tube because enzymes are not consumers in any reaction and they only bind to substrate and give products.

So the correct answer is B.
