4.2 Mechanism of Enzyme Action DB024

Each enzyme only has 1 substrate that will fit its active site.  What is this called?

• reusablility
• denaturation
• specificity
• fragility

The area that the substrate fits into on the enzyme is called the:

• Active Site
• Allosteric Site
• DiSulphide Bridge
• β-Pleated Sheet

The ____________________ mechanism describes how each substrate must fit into the enzyme.

• lock and key

• hammer and nail

• jigsaw puzzle

• seesaw

What makes an enzyme substrate specific?

• Size
• Shape
• Name
• Location it is found in

The "lock and key hypothesis" attempts to explain the mechanism of?

• Vacuole formation
• Pinocytosis
• Sharing of electrons
• Enzyme specificity 

In the diagram, what is letter A? 

• product
• substrate
• enzyme-substrate complex
• active site

Substrate needs an initial input of energy so that it can pass through the

• high temperature

• enzyme complex

• activation energy

• transition state

Letter D...

• active site
• enzyme
• substrate
• products

Enzymes possess active site, so that

• its shape is globular

• it can lowering the activation energy

• substrate can bind

• chemical reaction is faster

After the enzyme and substrate bind together and perform the reaction, what does the substrate become?

• a substrate
• an enzyme
• a product
• an active site
