The steroids are a class of molecules which are derived from the cholesterol in the adrenal gland.

The cortical cells in the adrenal glands produce steroid and steroid hormones from the cholestrol. The synthesis of steroid takes place in the smooth endoplasmic reticulum which forms a disc-like tubular network of the membrane but lacks ribosomes.

Since smooth endoplasmic reticulum are involved in the synthesis of steroid hormone and not the rough endoplasmic reticulum which is involved in the synthesis of proteins therefore, false is the correct answer.

Which of the following is a member of the class Polychaeta?
s344n2d4d5 [400]
Polychaeta generally refers to a class of annelid worms with segmented body parts.
