- Diagramming Cell Communication Remember: SHAPE DETERMINES FUNCTION Insulin is a hormone that is produced by the pancreas. It circulates around the body in the blood and binds to receptor proteins in the cell membrane of cells to "unlock" them and allow sugar to enter the cell. In people with type 2 diabetes, the shape of the receptor protein in the cell membranes is changed due to poor diet. As a result, insulin is no longer the correct shape to bind, and sugar stays in the blood. For this assignment, I would like you to make two hand written drawings: Show insulin correctly binding to a receptor protein in a normal person's cell membrane. Show insulin UNABLE to bind to a receptor protein in the cell membrane of a person with Type 2 diabetes. The receptor should be an INCORRECT SHAPE to match the insulin molecule.arrow_forwardDiagramming Cell Communication Remember: SHAPE DETERMINES FUNCTION Insulin is a hormone that is produced by the pancreas.

Some terms are used more than once] Rab, SNARE, v- SNARE, t-SNARE, Tethering a. Identification of a vesicle to be docked depends on a diverse family of monomeric GTPases called proteins. First, a filamentous protein on a target membrane binds to a protein on the surface of a vesicle. This interaction allows the vesicle to dock on its particular target membrane. A on the vesicle then binds to a complementary_ on the target membrane. Whereas and proteins provide the initial recognition between a vesicle and its target membrane, complementary appropriate target membranes. Together, the proteins ensure that transport vesicles dock at their proteins catalyze the final fusion of the two membranes by squeezing out water making fusion more energetically favorable. b.

- Please asap ?arrow_forwardBIOC 384 Overview of Cell Signaling Pathways Q7.2: A first messenger molecule activates a receptor that stimulates Enzyme A, which synthesizes 100 second messenger molecules. In turn, each second messenger activates only one molecule of Enzyme B, which once activated, phosphorylates 100 molecules of Enzyme C that each phosphorylate 75 molecules of Enzyme D. In the last step, each Enzyme D phosphorylates 50 transcription factors. How many transcription factors are phosphorylated in response to the first messenger binding to the receptor? How many transcription factors would be phosphorylated if one copy of the Enzyme D gene were inactivated (heterozygous genotype) so that there were only half the number of functional Enzyme D molecules in the cell? Explain.arrow_forwardthis question from bioengineering asaparrow_forward
