What is the activation energy?

• Energy needed to make reaction occur

• Energy needed foe enzymes

• Energy produced by enzymes

• Heat which is produced by by enzymes

What is the enzyme?

• molecules which accelerate a reaction

• molecule which stops reaction

• molecule which gives energy

• molecule which helps to lipid

What is the enzyme?

• molecules which accelerate a reaction

• molecule which stops reaction

• molecule which gives energy

• molecule which helps to lipid

How enzyme accelerates the reaction?

• by lowering activation energy

• by producing energy which is needed

• by creating energy between substrates

A molecule that an enzyme acts upon is called the __________

• substrate

• product

• inhibitor

• activation energy

The theory of enzyme action is called _____________________

• LOCK and KEY MODEL

• CAR and SPEED MODEL

• PEN and PENCIL MODEL

• BALL and TARGET MODEL

The Enzyme joins with substrate by its active site to form ________________

• enzyme–substrate complex

• enzyme-energy complex

• lock and key complex

What is the active site of enzyme?

• part of enzyme which binds to substrate

• part of enzyme which is not used in reaction

• part of enzyme which produces energy

What will happen to enzyme if active site losses its shape

• enzyme can't bind to substrate, but reaction will not happen

• enzyme can't bind to substrate, but reaction will happen

• enzyme can bind to substrate, but reaction will not happen

• it doesn't affect on enzyme
