Q

How do you start a chemical reaction?

A

chemical bonds need to be weakened in an “activation
process” where the molecules need to absorb energy

Q

What is substrates?

A

One particular reactant that enzyme shape binds with

16
Q

What is active site?

A

The region where an enzyme’s specific substrate can bind

17
Q

What is the enzyme-substrate complex?

A

Once a substrate binds we call it an enzyme-substrate complex, which lowers the activation energy needed for a chemical reaction to take place

18
Q

does enzymes allow any more after enzyme-substrate complex is complete?

A

YESS
reduce, reuse, recycle
