Biochemistry - Part 2 - Enzymes

Enzymes act as:

• Substrates

• Catalysts

• Inhibitors

• Coenzymes

Enzymes decrease the:

• Reaction product

• Activation energy

• Substrate level

• Temperature requirement

Enzymes are not:

• Specific

• Reusable

• Consumed in the reaction

• Selective

Non-protein molecules that assist enzymes are called:

• Apoenzymes

• Substrates

• Cofactors

• Allosteres

Enzymes increase the rate of biological reactions due to their:

• Size

• Density

• Catalytic power

• Affinity

Enzyme specificity depends on the:

• Temperature

• 3D structure of the substrate

• Source of enzyme

• Cofactor

All enzymes are proteins except:

• Coenzymes

• Catalase

• Ribozymes

• Transferases

Ribozymes are made of:

• Proteins

• Nucleic acids

• Lipids

• Sugars

Most enzyme names end with:

• -ose

• -ase

• -ide

• -ite

Enzymes work best at temperatures between:

• 10-20°C

• 35-40°C

• 60-70°C

• 90-100°C
