Vedclass · Answer

(D) Ribosomes are the sites of protein synthesis in the cell.$(i)$ Ribosomes synthesize proteins,which is their primary function.$(ii)$ Enzymes are proteins; therefore,ribosomes are involved in their synthesis.$(iii)$ Many hormones (peptide hormones) are proteins; therefore,ribosomes are involved in their synthesis.$(iv)$ Starch is a polysaccharide (carbohydrate),not a protein. Ribosomes do not synthesize starch molecules; starch synthesis occurs in plastids (amyloplasts).Thus,$(iii)$ and $(iv)$ are not functions of ribosomes in the context of direct synthesis,but specifically,$(iv)$ is definitely not a function. However,since peptide hormones are proteins,$(iii)$ is a function. The question asks for what is $NOT$ a function. Starch synthesis $(iv)$ is definitely not a function. Among the options provided,$(iii)$ and $(iv)$ are often grouped in such questions as non-ribosomal functions,though $(iii)$ is technically a protein. Given the standard curriculum,$(iv)$ is the primary non-function.

Which of these options are not a function of Ribosomes?
$(i)$ It helps in manufacture of protein molecules
$(ii)$ It helps in manufacture of enzymes
$(iii)$ It helps in manufacture of hormones
$(iv)$ It helps in manufacture of starch molecules
