Long-chain fatty acids have an alkyl chain of more than 10 carbon atoms. fatty acids with alkyl chains of this length are characterized as in terms of polarity and in terms of size. this length decreases their ability to cross the lipid bilayer of the mitochondrial membrane. as a result, such fatty acids are activated in the cytoplasm by . however, the resulting molecule, fatty acyl-coa, is still too to cross the membrane. therefore, a protein system involving carnitine is required for this transport to occur.

Saturated fatty acids,long, thiokinase,large

Explanation:

Long chain fatty acids have an alkyl chain of more than 10 carbon atoms.Fatty acids with alkyl chains of this length are characterized as saturated fatty acids in terms of polarity and long in terms of size.This length decrease their ability to cross the lipid bilayer of the mitocondrial membrane.As a result such fatty acids are activated in the cytoplasm by thiokinase.However the resulting molecule  fatty acyl CoA is still too large to cross the membrane.Therefore a protein system involving carnitine is required for this transport to occur.

do you have a picture?

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
