14) Which of the following correctly ranks the steps in the secretory pathway? 1. Active PKA subunits phosphorylate targets in the cell, regulating function. 2. The catalytic subunits of PKA dissociate. 3. Gprotein a subunit exchanges bound GDP for GTP. 4. CAMP binds to the regulatory subunits of PKA, activating it. 5. Ga subunit dissociates from complex and activates adenylate cyclase. 6. Ligand (hormone) binds to receptor. 7. Activated adenylate cyclase produces CAMP from ATP.
The activity provides you with a version of the NGF pathway, an example of a RTK. All of the proteins involved can be in ON/OFF states. Using this cell signaling pathway you will be asked a variety of questions to determine how the molecules are regulated, but also how a cell would respond if this cell signaling party steps were interrupted or activated.

All of the following are true of integrins except (a) they are receptor proteins (b) they help organize the cytoskeleton (c) they are part of the ECM (d) they are important in cell signaling (e) they are located in the plasma membrane
What property prevents the ligands of cell-surface receptors from entering the cell? The molecules bind to the extracellular domain. The molecules are hydrophilic and cannot penetrate the hydrophobic inferior of the plasma membrane. The molecules are attached to transport proteins that deliver them through the bloodstream to target cells. The ligands are able to penetrate the membrane and directly influence gene expression upon receptor binding.
Why are steroids able to diffuse across the plasma membrane? Their transport protein moves them through the membrane They are amphipathic, allowing them to interact with the entire phospholipid Cells express channels that let hormones flow down their concentration gradient into the cells They are non-polar molecules.

5) Briefly explain why the formation of a tumour can pose a risk to a person's homeostasis. 6) The functioning of the "Ras/MAPK" signal transduction pathway is absolutely essential in order for cells to grow, divide, and migrate. One important protein that is part of this pathway is BRAF. This protein is a kind of enzyme called a "kinase" – an enzyme that transfers a phosphate group onto another protein. In some melanomas, a mutated form of BRAF called BRAF Val600AGlu drives the progression of the cancer. The drug "vemurafenib" slows the progression of the cancer by slowing the production of the mutant BRAF protein. (National Cancer Institute. 2019. Types of Cancer Treatment.
