Enzymes

Question 1

What is an enzyme

Answer 1

An enzyme is a biological catalyst that speeds up chemical reaction without being consumed

Question 2

What is the function of enzymes in biological processes

Answer 2

Enzymes act as catalysts to speed up metabolic rea tions in living organisms.

Question 3

How do enzymes speed up chemical reactions

Answer 3

Enzymes lower the activation energy required for a reaction to occur.

Question 4

What is the active site of an enzyme

Answer 4

It’s the part of the enzyme where the substrate binds with it

Question 5

Explain the lock-and-key model of enzyme action

Answer 5

The enzymes active site is like a lock, and the substrate is like a key that fits perfectly, allowing the reaction to happen.

Question 6

What effect does temperature have on enzyme activity

Answer 6

Enzymes work best at their optimum temperature if it gets too hot the enzyme will be denatured

Question 7

How does pH affect enzyme activity

Answer 7

Enzymes work best at their optimum pH. If the pH is too high or too low, the enzyme can become denatured

Question 8

What is the substrate and broduct of the enzyme amylase

Answer 8

Substrate is starch
Product is Maltose

Question 9

What is the substrate and products for the enzyme lipase

Answer 9

Substrate is fats
Products is glycerol and fatty acids

Question 10

What is the substrate and products of the enzyme protease

Answer 10

Substrate is proteins
Products is peptides and amino acids

Question 11

Factors that affect enzyme activity

Answer 11

Temperature and pH
