Less

No change

Drag and Drop

Enzymes

the rate of reaction (reaction happens faster) by

the activation energy needed.

Drag these tiles and drop them in the correct blank above

increase

decreasing

stay the same

no change

Hotspot

If enzymes follow the lock and key model, meaning enzymes are specific to their substates, which substate best fit the enzyme?

Multiple Choice

Will an enzyme work if it has been denatured?

YES, the enzyme will continue to bind to substrates

NO, the enzyme will not be able to bind to substrates

Multiple Choice

Which enzyme is going to break down proteins?

Lipase

Protease

Amylase

Cellulase

Dropdown

Enzymes belong to which biomolecule

Multiple Choice

The enzyme lactase breaks down the sugar lactose, what will the enzyme do after the reaction is complete?

Lactase changes its structure and cannot be reused.

The enzyme lactase can be reused.

Lactase converts lactose into glucose permanently.

The enzyme lactase is destroyed after the reaction.

Multiple Choice

What is the optimum pH for the enzyme salivary amylase?

pH = 2

pH = 6

pH = 9

pH = 8

Multiple Choice

What is the optimum pH for the enzyme pepsin?

pH = 1

pH = 6

pH = 9

pH = 8

Multiple Choice
