Enzymes

Question 1

What are do enzyme do?

Answer 1

Enzymes are like tools that can cut, stick together, or rearrange substrates.

Question 2

What are enzymes?

Answer 2

Enzymes are biological catalysts which speed up chemical reactions, but remain unchanged themselves.

Question 3

What are products?

Answer 3

Products are the substances which are produced by a reaction.

Question 4

What are substrates?

Answer 4

Substrates are the substances which and enzyme works on.

Question 5

What is the specific?

Answer 5

Specific is the term used to describe the fact that one enzyme can work on only one substance.

Question 6

Can enzyme reactions change the activity site of enzymes?

Answer 6

Enzyme reactions could change the activity site and make it harder for substrates to fit and the enzyme won’t work as well.

Question 7

Does the enzyme return to its original state after the chemical reaction?

Answer 7

Yes! The enzyme returns to its original state (not enzyme - substrate complex) after the completion of the reaction.

(Induced Fit)

Question 8

Describe the effect of temperatures on the function of an enzyme?

Answer 8

Temperatures hotter than 37 C decrease the activity of an enzyme and make it less effective.

Question 9

Describe the effect of pH level on the function of an enzyme?

Answer 9

pH levels higher than 7 decreases the activity of an enzyme and makes it less effective.

Question 10

Describe the diagram of enzymes

Answer 10

It starts out with an enzyme and a substrate that each have a shape. The active site is where the the substrate fits into the enzyme.

Then the enzyme grabs onto the substrate.

Then the products (substrate split in half) + enzymes are released from each other’s connection and the enzyme returns to the original state as it was in the first step.
