Answer:
Enzymes are proteins that increase (only) the rate of chemical reactions converting substrate into product.
Catalysts are substances that increase or decrease the rate of a chemical reaction but still remain unchanged.
Answer: B
Explanation:
Synthesis of an inducible enzyme requires the substrate bound to repressor.
In the synthesis of a specific inducible enzymes, a substrate on which the enzyme acts must bind to the repressor that prevents the synthesis of the inducible enzyme. Example of an inducible enzyme is β-galactosidase in Escherichia coli that degrades lactose and galactose.
The synthesis of β-galactosidase is regulated by a repressor protein, that binds to the region of deoxyribonucleic acid (DNA) that codes for the synthesis of β-galactosidase. If lactose or galactose (substrate) is present, it acts as an inducer which induce the repressor protein from binding to DNA. Hence the enzyme is synthesized
An aim identifies the purpose of the investigation. It is a straightforward expression of what the researcher is trying to find out from conducting an investigation.
The aim typically involves the word “investigate” or “investigation”. there it is :)
