5.1 Enzymes

Define catalyst.

speeds up rate of cellular reactions & isn’t changed by reaction

Define enzyme.

proteins that act as biological catalysts & are coded for by genes

How do enzymes speed up reactions?

lowering activation energy required for reaction to proceed

What is the basic unit of enzymes?

amino acids

Why are enzymes important?

reactions are slow asf & cells die if not sped up

small

Are enzymes used over and over again?

yes

Are enzymes living?

no

What is the suffix for enzymes?

-ase

What is specificity?

enzymes usually only act on a single specific substrate

Specificity
> __ bind with the __ __
>> reaction takes place here
>> s__ is specific for substrate (c__)
