Place the following steps of insulin production (secretion) in the correct order. Glucose is converted to glucose-6-phosphate Ca+2 causes vesicles carrying insulin to fuse with the cell membrane, releasing insulin into the blood. Ca + 2 channels open to allow Ca + 2 to enter the cell Glucose is imported into the cell. ATP closes K + channels Glucose-6-phosphate is used in respiration to generate ATP QUESTION 14 What is the signal that allows the tyrosine kinase receptor to phosphorylate itself? activation of the Pas protein phosphorylation by the MAP kinase pathway binding of the ligand to the tyrosine kinase receptor binding of GTP.
