WebApr 13, 2024 · The transport of phosphate (PO 4) through the luminal membrane of the renal proximal tubule cells is an active secondary transport coupled to the passive flow of sodium that is carried out by means of the Na +-PO 4 − co-transporters. Like other substances with facilitated diffusion and active transport, the tubular reabsorption of PO 4 is saturable. … Webphospholipid, also called Phosphatide, any member of a large class of fatlike, phosphorus-containing substances that play important structural and metabolic roles in living cells.
WebPhosphorylation allows cells to accumulate sugars because the phosphate group prevents the molecules from diffusing back across their transporter. Phosphorylation of glucose is a key reaction in sugar metabolism.
