Scientists are studying a plant of the Amaranthaceae family which is known to be able to photosynthesize at high temperatures. A closer look at the cells show that by itself, a single cell will not photosynthesize at all, but when there are a group of cells, photosynthesis occurs. When a group of cells are present, they will produce chemical A, which will act as an extracellular ligand to trigger the production of cAMP which leads to the production of rubisco. To study the plant even further, the scientists have developed 2 drugs, Drug K and T. Drug K is a hydrophobic molecule which binds to G-proteins inhibiting it and makes any endomembrane system impermeable to NADP+. The activity of chemical A decreases as the concentration of drug K increases. Drug T is a hydrophilic molecule that binds to receptor tyrosine kinases to trigger a cascading phosphorylation event to produce cyclin. 1. What are the detailed methods of actions (how do they work, what do they do) of the Amaranthaceae plant, Chemical A, Drug K and Drug T? 2. You are preparing a demonstration of the Amaranthaceae cells photosynthesizing tomorrow, however, there has been a spill of drug K into the culture of Amaranthaceae cells which you are growing, how can you ensure that by tomorrow your culture of cells are photosynthesizing without replacing the entire culture? Explain in detail why your method would work and how does it work.
