In steroid synthesis the rate limiting step is the side chain cleavage and this step is affected by the group of enzymes known as
a. aromatase.
b. desmolase.
c. oxido-reductase.
d. sulfatase.
e. inolase.

The correct answer is B.

Explanation:

Cholesterol desmolase, also known as side-chain cleavage enzyme catalyzes the conversion of cholesterol into pregnenolone, which is the limiting step in steroid synthesis.

This enzyme is of the family cytochrome P450, the specific gene for this enzyme is CYP11A1.

a less-active, mature cell in areolar connective tissue would be a:

a. fibroblast

b. fibrocyte

c. chondroblast

d. chondrocyte
