Question

With regard to enzymes, what can be said to be the relationship between the substrate and the active site? A) One substrate can bind to the active site and is changed into products. B) Every active site will always accept multiple substrates in order to produce a new product. C) The active site of an enzyme combines with the substrate, when a product is given to the enzyme, producing a new molecule. D) A specific product fits into the active site of an enzyme. The enzyme then breaks down the product to make a new substrate.

Answer 1

It would be A), one substrate can bind to the active site and is changed into products n

Answer 2

The correct answer is option A

The reaction between a substrate and active site is specific. It is like the lock and key model. One substrate can bind to the active site and is converted into product. The active site of an enzyme is very much specific for the substrate that is going to bind with it. It does not allows more than one substrate to bind with the active site of the enzyme.
