You've helped me so much...I regret not knowing you before ... I have a request can I please have an explanation on gametogenesis, oogenesis and spermatogenesis
Then how lipid soluble drugs cross semipermeable membrane easily even phospholipid bilayer have hydrophilic ends? The drugs should get repelled right? But how lipid substances cross barrier easily than water soluble drugs
the cell membrane is semi permeable and selectively permeable in nature which means there are small and big molecules which are being transported so small ones can move easily and big ones cannot reflecting semi permeable nature on the other side if big ones are necessary or needed so they can move only if membrane allows through embedded proteins which reflects selectively permeable nature... hope it helps:)
