Question

Select all of the following functions of lipids that are essential to living organisms.

Comprise the plasma membrane of cells and gives them flexibility.
Provide comparatively light-weight long term energy storage.
Comprise vital hormones and chemical signalers.
Store genetic material.

Answer 1

Lipids are crucial for energy storage, cell membrane structure, and the formation of hormones and signaling molecules, but they do not store genetic material.

Step-by-step explanation:

Lipids play several vital roles in living organisms, which include:

• Energy Storage: Lipids serve as a source of long-term energy storage. They are an efficient way to store energy due to their comparatively light weight and high energy content.
• Cell Membrane Structure: Phospholipids, a type of lipid, are major components of the plasma membrane of cells, providing flexibility and protecting the interior of the cell.
• Hormones and Signaling: Lipids comprise vital hormones and chemical signalers that regulate physiological processes.

However, lipids do not store genetic material; this function is primarily carried out by nucleic acids such as DNA and RNA.

Answer 2

The essential functions of lipids for living organisms are: Comprise the plasma membrane of cells and gives them flexibility. Provide comparatively light-weight long term energy storage. Comprise vital hormones and chemical signalers

Comprise the plasma membrane of cells and gives them flexibility.is a crucial function as it forms the outer barrier of cells, regulating what enters and exits. The lipid bilayer structure provides flexibility and fluidity, essential for cell movement and function.

Provide comparatively light-weight long term energy storage. Fats and oils are more energy-dense than carbohydrates and proteins, making them efficient long-term energy reserves. This is particularly important for animals and some plants that need to store energy for extended periods.
