Membranes are important structural features of cells. a. describe how membrane structure is related to the transport of materials across the membrane. b. describe the role of membranes in the synthesis of atp in either cellular respiration or photosynthesis.

A)   The  cell  is  made  up  of  phospholipids with  hydrophilic  layer  outward  which  has  different  protein  and  receptors  in  between   that  help  in  transportation  of  different  substance  across  the  membrane

B)  The  inner  membrane  of  mitochondrion  contain  the  ATP synthase  that  is  responsible  to  make  ATP  out  of  ADP  and  inorganic  phosphate
