Vedclass · Answer

(B) $Dihydroxyacetone$ $phosphate$ $(DHAP)$ is a phosphorylated sugar intermediate involved in glycolysis and the Calvin cycle.Because it carries a negatively charged phosphate group,it is highly polar and hydrophilic.Biological membranes consist of a lipid bilayer,which is hydrophobic in its interior.Charged or highly polar molecules like $DHAP$ cannot freely diffuse across the lipid bilayer of the cell membrane.Therefore,$DHAP$ cannot pass through the cell membrane without specific transport proteins.

Which of the following statements is true regarding $Dihydroxyacetone$ $phosphate$ $(DHAP)$?
