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

All enzymes are

• proteins

• lipids

• carbohydrates

• vitamins
