Answer:
The two types of molecules synthesized by smooth endoplasmic reticulum is phospholipid molecules of plasma membrane and steroid hormone.
Step-by-step explanation:
Endoplasmic reticulum is one of the most important organelle found inside the cytoplasm of eukaryotic cell.Endoplasmic reticulam is of two types
1 Rough endoplasmic reticulum contain ribosome on its surface which is responsible for the roughness of this endoplasmic retuculum.Rough endoplasmic retuculm help in protein synthesis.
2 Smooth endoplasmic reticulum does not contain ribosomes in its structure.Smooth endoplasmic reticulum is found in large amount in the testis ans ovaries of human.
Smooth endoplasmic reticulum play a significant role in the biosynthesis of phos pholipid of plasma membrane along with the production of various steroid hormones such as testosterone.
