Enzymes

Definition

The are proteins which function as biological catalysts that speed up rate of chemical reaction with being chemically changed

Words that you would encounter

Enzyme

Products

Substrate

Lock and key method

The lock becomes the enzyme while the key becomes the substrate

The place where the key enters in is called the 'Active Site'

It becomes the Enzyme-Substrate Complex

The substrate breaks down and becomes product

"Key"

"Lock"

Active Site

It is an site where the substrate binds complementarily to the enzyme

The substrate after being broken down

Only specific substrates can fit into specific enzyme's active site

Temperature On Enzyme Activity

Low Temp

High temp

The enzymes become denatured

the enzymes are inactive

As the temperature increases, the activity of enzymes increases and the speed of reaction also increases

Optimum Temp

The enzyme is most active

The rate of reaction is the fastest

Active site changes shape
