I WONDER - What Is An Enzyme Substrate?

What is the term used to describe the specific molecule that an enzyme acts upon?

• Inhibitor

• Catalyst

• Substrate

• Product

Which of the following best describes the relationship between an enzyme and its substrate?

• The enzyme and substrate fit together like a key and lock.

• The enzyme changes its shape to fit any substrate.

• The substrate changes its shape to fit the enzyme.

• The enzyme and substrate repel each other.

Why is enzyme specificity crucial for living organisms?

• It helps enzymes to change their structure easily.

• It ensures that each enzyme catalyzes only its designated reaction.

• It prevents enzymes from being used up in reactions.

• It allows enzymes to work on multiple reactions at once.

How do enzymes contribute to the efficiency of biochemical reactions?

• By slowing down the reaction rate.

• By ensuring reactions proceed quickly and efficiently.

• By changing the pH of the reaction environment.

• By increasing the temperature of the reaction.

What is one of the main roles of enzymes in biochemical processes?

• To interfere with other processes.

• To ensure reactions proceed without interference.

• To act as a reactant in the reaction.

• To change the products of the reaction.
