Question

In animal cells lipid like steroid hormones are synthesized in:

• A. Rough Endoplasmic reticulum
• B. Lysosomes
• C. Smooth Endoplasmic reticulum
• D. Centrioles

Answer 1

Answer:

C. Smooth Endoplasmic reticulum

• Steroid hormones are a group of hormones derived from cholesterol that act as chemical messengers in the body.

• The lipid-like steroidal hormones in animal cells are synthesized in the smooth endoplasmic reticulum and also mitochondria.

• The smooth endoplasmic reticulum has no ribosomes attached to it , hence, is responsible for production of steroid hormones in the adrenal cortex and endocrine glands.

• As they are made of lipids , they cannot mix with the the plasma of cell and are made to transport proteins and bind to it.

• Example : Testosterone and progesterone are the steroid hormones.
