BIOL 1201 : Bio Final- Cell Signaling
Document Summary
Allow signals to function differently in different cells. For one molecule of epinephrine, 100,000,000 molecules of glucose are made. This process is shown as a cascade because you get a sort of waterfall effect as one step leads to another. The two types of muscle cells have different signal-transduction pathways for epinephrine and thus have different cellular responses. Arm- two sets of muscles working against each other. Whether or not a function occurs in a plant is controlled by two different hormones that need to be in balance. Auxins are primarily produced by the meristem and transported down the plan. Cytokinins are primarily produced by the root and are transported up the plant. Some plant processes (flowering, etc. ) follow a daily cycle suggesting plants have rhythms. Biological clocks all work by measuring the accumulation of something or the breakdown of something. Pr is converted into pfr by sunlight quickly, but pfr is chemically converted into pr slowly.
