Question

in a patch of animal cell membrane about 10 μm in area, which will be true?
choose one:
there will be about an equal number of proteins and lipids.
there will be more lipids than proteins.
there will be more proteins than lipids.
there will be more carbohydrates than lipids.
because the lipid bilayer acts as a two - dimensional fluid, there is no way to predict the relative numbers of proteins and lipids in any patch of cell membrane.

Explanation:

Cell membranes are primarily composed of a lipid - bilayer. Lipids are the most abundant component in terms of number. Proteins are embedded in or associated with the lipid - bilayer, but their number is less than that of lipids. Carbohydrates are usually present as part of glycolipids or glycoproteins and are less abundant than lipids. The fluid nature of the lipid - bilayer does not prevent us from knowing the general composition ratios.

Answer:

There will be more lipids than proteins.
