Where do the proper enzymes come from? outside the cell synthesized from coded information of gene rna unknown

The correct answer is option (B) synthesized from coded information of gene .

Enzymes are biocatalysts that accelerate the rate of biochemical reactions without undergoing any change. A majority of the enzymes are proteins. They are produced by the ribosomes present in the cytoplasm of the cells.  The DNA has the coded information for the production of these enzymes. The coded genetic information in the gene is used for the production of enzymes. The information is transcribed into a messenger RNA, which along with the tRNA and ribosomes produces enzymes that are basically proteins through the process of translation. After the synthesis, they are modified by the Golgi apparatus of the cell.

where in your body is there an enzyme that does function at a high or low ph? what is the name of that enzyme and its function?
