The diagram shows the mechanism of enzyme action. What does P represent?

Based on question 4, choose 2correct answers that best explained the enzyme characteristics

• enzyme is reusable

• highy specific to the substrate

• enzyme structure remain unchanged

• reversible reaction

Enzymes are made up of

• carbohydrate

• lipid

• wax

• protein

A small amount of enzymes can act on a

large amount of substrate because

• enzymes do not change after a reaction and can be used again

• a little enzyme can supply enough energy to carry out a reaction.

• as the reaction is going on, more enzymes are produced.

• enzymes act in a all or none situation.

Extracellular enzyme is produced by

• free ribosome in cytoplasm

• ribosome in RER

• Amylase

• Lipase

• Protease

• Tyrpsin

The graph shows the effect of pH on enzyme activity.The optimum pH for the activity of the enzyme is

• pH 1

• pH 3

• pH 7

• pH 9
