Question

Based on the given graph showing the amount of reactant, product, and enzyme over the course of a biochemical reaction taking place in a test tube, the correctly identified line is

• A. Line 1 is the enzyme
• B. Line 2 is the substrate
• C. Line 3 is the product
• D. Line 2 is the enzyme
• E. Line 1 is the substrate

Answer 1

The correct option is D Line 2 is the enzyme

Enzymes are the biomolecules that enhance the rate of the reaction without being consumed in it. Line 2 exhibits enzyme concentration which is constant through out the reaction. With time, substrate (line 3) is being converted into product (line 1) resulting in decreased substrate concentration and increased product concentration. Thus, the correct answer is option D.
