When yоur blооd glucose levels аre high, cells in your pаncreаs release a protein hormone called insulin. Insulin helps lower your blood glucose by activating membrane protein transporters that move glucose from the blood into your cells without requiring ATP. What type of membrane transport is described? Choose one, then explain your choice below. (5 pts) simple diffusion facilitated diffusion active transport endocytosis exocytosis Describe the step-by-step path (cell organelles and structures) taken when a pancreatic cell needs to produce and secrete insulin into the bloodstream. Your answer should start with the gene for insulin (DNA) and end with insulin being secreted from the cell. (10 pts) If the gene for insulin experienced a single mutation where an alanine (a nonpolar amino acid) was replaced with a serine (a polar amino acid) in the amino acid sequence, would that cell most likely produce a functional insulin protein? Why or why not? (5 pts) Compare the properties of glucose (shown below) to those of the cell membrane. Why is glucose not able to simply diffuse across the cell membrane into your cells that need it? Consider and discuss the polarity of the molecules. (7 pts)
