NR507 THE CELL FINAL EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS | 100% PASS (A+ CERTIFIED) 1. cell to cell Correct Answer And since most organs are multicellular, and including humans, cell to cell communication is important to regulate growth and cell division, tissue organization, and to coordinate all other cellular functions not only between adjacent cells, but also distant cells. 2. But cells do communicate with each other by three different processes. Correct Answer gap junctures contact signalling by plasma membrane bound receptors remote signaling by secreted molecules 3. gap junctions This allows direct cell to cell contact via secreted chemicals that travel directly between the connected cells. This is a very important way for cells, for example, cardiac muscle within a specific organ to communicate and coordinate activity. Correct Answer This allows direct cell to cell contact via secreted chemicals that travel directly between the connected cells. This is a very important way for cells, for example, cardiac muscle within a specific organ to communicate and coordinate activity. 4. contact signalling by plasma membrane bound receptors Correct Answer Secreted chemicals such as hormones, neurotransmitters, cytokines can travel from cell to cell across near or far distances often transport at via the bloodstream to bind to receptors on the target cell surface. This is a very important way for all cells to control normal and in some cases also abnormal or tumor-type growth. 5. remote signaling by secreted molecules Correct Answer Secreted chemicals, again hormones, cytokines can travel from cell to cell, across near or far distances often transported via the bloodstream and in some cases actually enter directly into the target cell. 6. So what happens when the secreted chemical reaches its target cell by any of these 3 processes? Correct Answer Signal transduction, the process whereby chemical signals received on the surface of the cell trigger a cascade of biochemical events within the cell. Signal transduction is analogous to what happens when you make a phone call and somebody at the other end picks up that call. 7. cellular metabolism Correct Answer All of the chemical reactions that are occurring are part of maintaining cellular function, and we refer to those as cellular metabolism Metabolism has two parts to it, anabolism or synthetic reactions, energy using reactions to make things for the cell.Metabolism also includes catabolism, degredative type reactions, reactions that break material down to release energy for the cell. 8. how is ATP formed Correct Answer Dietary proteins, fats, carbohydrates, it's the stuff that we eat. In chemistry, we refer to that as the substrates. These materials are broken down, in chemistry we refer to that as hydrolyzed. 9. There are three distinct steps or phases in the metabolic pathways that form
