Key Area 1.4

Revision for Key area 1.5 Proteins and Enzymes

Name the sub units which make up all proteins Amino Acids
Name all 5 categories of proteins Structural Hormones Antibodies Receptors Enzymes (SHARE)
State the function of Enzymes Catalyse biological reactions
State the function of antibodies Part of immune systems which helps fight infection
The chemicals that enzymes act upon are called ... substrates
The chemicals produced by the action of an enzymes are called ... products
Substrates bind to which part of the enzyme? Active site
How are enzymes specific The shape of an enzyme's active site is complementary to the shape of its specific substrate or substrates
What are optimum conditions? The conditions under which a particular enzyme is most active are called the optimum conditions.
Name 2 conditions where enzymes have an optimum Temperature and pH
Describe the rate of an enzyme at a low temperature/below the optimum At low temperatures enzyme activity is low but increases as it approaches the optimum temperature
Describe the rate of an enzyme at a low temperature/below the optimum Rate decreases until the enzyme is denatured
What is denaturation? At high temperatures the shape of the enzyme is altered so that it is no longer complementary to its specific substrate. This is irreversible.
Describe enzyme activity at a pH which is not the optimum As the pH value is increased above or decreased below the optimum pH the enzyme activity decreases.
