Which one of the following is not true for enzymes?
They act on a specific substrate
They are made up of fat and sugar
They act at a specific temperature
They act at a specific pH
Solution
B.
They are made up of fat and sugar
Enzymes or biocatalysts are exclusively proteinaceous substances capable of catalysing chemical reactions of biological systems without themselves undergoing any change. There are certain factors that affect enzymatic activity:
- Temperature
- pH
- Enzyme concentration
- Substrate concentration
- Presence of inhibitors or activators
