Eukaryotic cell membranes contain large lipid molecules called sterols, whereas prokaryotic membranes lack sterols. One argument supporting the presence of these sterols in eukaryotes is that .

The options are not given, here are the options.

A.sterols are essential catalysts for the efficient functioning of the cell membrane

B. Eukaryotic nutrients are rich In sterols, which then become embedded In the membrane

C. Unlike prokaryotes, many eukaryotes lack the protection of a cell wall and therefore require sterols to add some strength and rigidity to the membrane

D. sterols are necessary membrane molecules that mediate the transport of dissolved nutrients from the cell environment to the cytosol

The Correct option is D.

Explanation:

Sterols are organic substances or lipids that occur naturally in plants , fungi and animals. They regulate biological processes and sustain the cell membrane. In eukaryotic cells, steroid help to maintain the membranes and convey different biological processes. The sterols bring the transportof dissolved nutrients frim the cell environment to cystol and serve as secondary messenger developmental signalling.

allowed for the prediction of the properties of missing elements.
