Question

Enzymes are important in cell's chemical reaction. Describe what a enzyme's role in chemical reactions is and explain what an enzyme does. The following key words may help you structure your response: active site, enzyme-substrate complex, and activation energy. Please try to use...

Answer 1

Answer:

Enzymes are proteins that catalyze chemical reactions that occur in living things. They accelerate the speed of reactions, which contributes to metabolism. Without enzymes, many reactions would be extremely slow.

Explanation:

Each enzyme is specific to a type of reaction. That is, they only act on a given compound and always perform the same type of reaction. The compound on which the enzyme acts is generally referred to as substrate. The great enzyme-substrate specificity is related to the three-dimensional form of both.

The enzyme binds to a substrate molecule in a specific region called a binding site. For this, both the enzyme and the substrate undergo conformation change for the socket.

They fit perfectly like keys in locks. We call this behavior the Key-Lock Theory.

Answer 2

Answer:

Enzymes are proteins that allow certain chemical reactions to take place much quicker than the reactions would occur on their own.

Explanation:

Enzymes function as catalysts, which means that they speed up the rate at which metabolic processes and reactions occur in living organisms.
