Why? How do water morcules move in and out of cells counts for over 70% of the human body. If water levels are not regulated and maintained in an is the consequences can be disastrous. Cells and tissues may well, blood cells burst, or the brain muy expand so much it pushes on the skull, leading to brain damage and death. So what exactly is the process that allows organisms to regulate and maintain their water content? Model 1 -...

State rational for your answer: 6) In unstimulated muscle cells, the glucose transporter Glut4 is present in the membrane of endosomes. Upon stimulation of these cells with insulin, the endosomes fuse with the plasma membrane, thereby depositing Glut4 in the plasma membrane, where it serves to transport glucose into the cells. In order for insulin to elicit this change in Glut4 localization, insulin...
