Q

Which of the following is not a function of fat in the human body?

A. protects the body from temperature extremes

B. cushions the internal organs from physical shock

C. carries the water-soluble nutrients

D. provides the major material from which cell membranes are made

A

Answer: C. carries the water-soluble nutrients

Fat is used by the body as a source of fuel. Of the options listed, option C is not a function of fat in the human body as fats are not carriers of water-soluble vitamins. Instead, they are carriers of fat-soluble vitamins (vitamins A, D, E, and K). The cells in our body are covered by a membrane made of phospholipids, cholesterol, and triglycerides. These lipid components affect the arrangement of the membrane and therefore, its fluidity.

Fats also help in offering insulation for bones to limit friction and eliminate physical shock. It also helps in protecting delicate tissues and organs from harm and danger when they come in contact with hard surfaces. The blanket layer formed by subcutaneous fat functions as an insulator for the body against extreme temperatures, and in keeping the general temperature of the body under control.
