Question

like carbohydrates, lipids are one of the main groups of organic compounds found in cells.
which of the following are the primary functions of lipids? select the two best choices.
to control cell processes, such as growth and repair
to supply energy for a cells immediate use
to form cell membranes that separate the contents of cells from the environment
to be stored for later use as an energy source

Explanation:

• Controlling cell processes (growth/repair) is a role of proteins/enzymes, not lipids.
• Immediate cell energy is primarily provided by carbohydrates, not lipids.
• Phospholipids are the main structural component of cell membranes, forming the lipid bilayer that separates the cell from its environment.
• Lipids (like triglycerides) are stored in cells as long-term energy reserves, broken down when needed for later energy use.

Answer:

to form cell membranes that separate the contents of cells from the environment
to be stored for later use as an energy source
