Lipids/fats play important roles in living things, including making up the majority of ALL cell membranes. Select the one correct role they do for living things from the choices below.
a
excellent insulators
b
low calorie source of dietary fiber
c
enzymes
d
primary energy source produced in photosynthesis
d
primary energy source produced in photosynthesis
The correct role of lipids/fats in living things is:
d) primary energy source produced in photosynthesis
To determine the correct role of lipids/fats in living things, let's examine the options provided:
a) Excellent insulators: Lipids/fats do have insulating properties, but this is not their primary role in living things.
b) Low-calorie source of dietary fiber: Lipids/fats are not a significant source of dietary fiber, so this option is incorrect.
c) Enzymes: Enzymes are actually proteins, not lipids/fats. Thus, this option is incorrect.
d) Primary energy source produced in photosynthesis: This is the correct answer. Lipids/fats serve as a long-term energy storage molecule in living things, and they are produced through the process of photosynthesis in plants.
Therefore, the correct answer is option d: primary energy source produced in photosynthesis.
