1What is an intracellular Enzyme?
- AAn enzyme which works outside a cell
- BAn Enzyme which works inside a cell
- CA Biological Catalyst
2What are the main Properties Of an Enzyme as protein
- AA Globular Protein
- BInfluenced by temperature only
- CInfluenced by Temperature and pH
- DIncreases the rate of a reaction
3What is the Activation energy?
- AEnergy required to Turn Substrate in to product
- BEnergy required to Break bonds in a molecule
- CEnergy require to denature an enzyme
4What is the lock and key mechanism?
- AWhere peptide bonds are hydrolysed
- BWhere a substrate has a shape which is complementary to the active site
- CWhere reaction produces an enzyme-substrate complex
5What is a Cofactor?
- AA non protein component of an enzyme required for enzyme to carry out reactions
- BA molecule which binds to part of an enzyme that is not the active site changing the shape of an enzymes tertiary structure
- CA molecule with a similar shape to to the substrate which fits i to an enzyme slowing the rate of reaction
6What is a competitive Inhibitor?
- AA non protein component of an enzyme required by enzymes to carry out a reaction
- BA molecule which has a shape similar to that of a substrate which fits in to the active site of an enzyme slowing the rate of a reaction
- CA molecule which binds to part of an enzyme which isn't the active site and changes the tertiary structure of the enzyme
7What happens when the pH changes from the optimum?
- AThe shape of the enzyme changes
- BThe affinity of the substrate for the active site decreases
- CNothing
- DThe rate of the reaction increases
8What happens when the temperature is at optimum
- AThe Rate of reaction is at its slowest
- BThe rate of reaction it at its fastest
- Csubstrates no longer fit the active site
