Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the main function of lipids?
A
energy storage, cell membranes, waterproof coverings
B
genetic material of all living things
C
main source of energy for cells
D
structure, function, regulation of body
Explanation: 

Detailed explanation-1: -Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of lipids called fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic birds and mammals dry because of their water-repelling nature.

Detailed explanation-2: -Lipids are fatty compounds that perform a variety of functions in your body. They’re part of your cell membranes and help control what goes in and out of your cells. They help with moving and storing energy, absorbing vitamins and making hormones.

Detailed explanation-3: -The main biological functions of lipids include storing energy, as lipids may be broken down to yield large amounts of energy. Lipids also form the structural components of cell membranes, and form various messengers and signaling molecules within the body.

Detailed explanation-4: -As structural components of the plasma membrane, lipids are responsible for contributing to membrane tension, rigidity, and overall shape. After an injury, the biophysical properties of the plasma membrane, and the individual lipids themselves, are altered, eliciting changes to membrane rigidity and fluidity.

Detailed explanation-5: -In organisms, lipids are a dietary source of energy and a method of long-term energy storage. They provide waterproof coverings, and lipids make up the membranes of cells and most organelles.
