Q:

In which one of the following types of connective tissues in animals does fat get stored?

A) Adipocyte	B) Chondrocyte
C) Osteocyte	D) Reticulocyte

Answer & Explanation Answer: A) Adipocyte

Explanation:

Adipocytes are the major source of leptin production, and plasma leptin concentrations directly correlate with the amount of total body fat.

Adipocytes are highly specialized cells that play a crucial role in the energy balance of most vertebrates.

Adipocytes convert excess energy to tri-acylglycerol and deposit it during feeding in preparation for periods of food deprivation.

Adipocytes may become enlarged by increased fat storage
