Enzymes

Question 1

What is the function of enzymes?

Answer 1

speed up chemical reactions within living organisms by lowering the activation energy needed for a reaction to occur

Question 2

What is the difference between anabolism and catabolism?

Answer 2

Anabolism refers to the building up of molecules, while catabolism refers to the breaking down of molecules.

Question 3

Why is the shape of an enzyme important?

Answer 3

it determines which specific substrate molecules can bind to its active site, allowing for highly selective chemical reactions to occur

Question 4

Does the shape of an enzyme change during a reaction?

Answer 4

Yes, the shape of an enzyme can change during a reaction.

Question 5

What environmental changes can affect enzymes?

Answer 5

Environmental changes such as temperature and pH can affect enzyme activity.

Question 6

What does enzyme specificity mean?

Answer 6

Enzyme specificity refers to the ability of an enzyme to select and catalyze a specific substrate.

Question 7

What is enzyme/substrate fit?

Answer 7

Enzyme/substrate fit describes how well an enzyme and its substrate match.

Question 8

What is induced fit?

Answer 8

Induced fit is a model that describes how an enzyme changes shape to better fit the substrate.
