Ion transporters can be regulated in a variety of different ways such as phosphorylation, allosteric inhibition or activation, and sensitivity to ion concentration. Using protein kinases to add a phosphate group or phosphatases to dephosphorylate the protein can change the activity of the transporter. Whether the protein is activated or inhibited with the addition of the phosphate group depends on the specific protein. With allosteric inhibition, the regulatory ligand can bind into the … WebApr 10, 2024 · Indescribable things to classic xl penis enlargement pump him I m in love those toys rong yu must be a constant play he suddenly wanted to cry this .
