Define/Explain the following terms:
$(i)$ Active transport
$(ii)$ Polysome
$(iii)$ Inclusion bodies

(N/A) $(i)$ Active transport occurs against the concentration gradient. This process requires the expenditure of metabolic energy,typically in the form of $ATP$.
$(ii)$ When multiple ribosomes are attached to a single $mRNA$ strand,they form a chain-like structure known as a polysome or polyribosome. This structure facilitates the simultaneous translation of a single $mRNA$ into multiple polypeptide chains.
$(iii)$ Inclusion bodies are non-membrane-bound structures found in the cytoplasm of prokaryotic cells. They serve as storage sites for reserve materials such as glycogen granules,phosphate granules,and cyanophycean granules. Note: The original prompt's description regarding enzymes and presence in eukaryotic cells is incorrect; in standard biology,inclusion bodies are characteristic of prokaryotes.
