WebIt seems like the question stem itself meant to ask about increasing temperature with cholesterol present rather than the amount of cholesterol. But I also question why it has melting temp and freezing temp as two separate choices when they are the same. Is the actual MCAT likely to use melting temp and freezing temp as different terms? WebCholesterol allows the lipid bilayer to maintain its fluidity despite the fluctuation in the body’s temperature due to events such as increasing metabolism. Cholesterol binds to the hydrophobic tails of the lipid bilayer. When the temperature is low, the cholesterol molecules prevent the hydrophobic tails from compacting and solidifying.

WebShort answer- Yes. Long answer- Yes- isoprene units are assembled into squalene which undergoes a cycloaddition reaction that automatically generates 4 rings to give lanosterol (a triterpenoid).
