A cell without ribosomes will not be able to produce enzymes.
An enzyme can still function if the shape of its active site is altered.
All enzymes are biological catalysts.
Enzyme action is affected by temperature and pH.
Break down of proteins into polypeptides in the duodenum
Curdling of milk in the stomach
Digestion of cellulose by bacteria
Emulsification of fats
PH 2, 25°C
PH 2, 70°C
PH 7, 25°C
PH 7, 70°C
Fatty acids and glycerol
1 and 2 only
1 and 3 only
2 and 3 only
All of the above.
Enzymes allow chemical reactions to take a shorter time to complete.
Enzymes are temperature sensitive.
Enzymes break down complex substances only.
Enzymes catalyse reversible reactions.
The lock represents the enzyme while the key represents the substrate.
The lock represents the active site while the key represents the enzyme.
The lock represents the product while the key represents the substrate.
The lock represents the enzyme while the key represents the product.
