Brian Patrick Green takes a first shot at articulating them and suggests this might … WebLiving organisms have some senses (sight, smell, touch, taste, etc.) that can help them to detect changes in their external environment, as well as their internal balance and respond to them. Some organisms (such as herbivores) respond to stimuli much quicker than others (such as plants). Homeostasis WebAfter you eat a meal, your blood glucose levels rise, triggering the secretion of insulin from β cells in the pancreas. Insulin acts as a signal that triggers cells of the body, such as fat and muscle cells, to take up glucose for use as fuel. Insulin also causes glucose to be converted into glycogen—a storage molecule—in the liver. chuck smith john 21

WebG-proteins act as mediators of cell signaling pathways that involve relay signaling molecules called second messengers. In the case of rhodopsin excitation, transducin activates an enzyme called phosphodiesterase, which cleaves a second messenger known as cGMP (3′5′-cyclic guanosine monophosphate) into 5′GMP. WebIn general, cellular response to stimuli is defined as a change in state or activity of a cell in terms of movement, secretion, enzyme production, or gene expression. Receptors on cell … chuck smith john 1WebA receptor or receptor cell is changed directly by a stimulus. A transmembrane protein receptor is a protein in the cell membrane that mediates a physiological change in a neuron, most often through the opening of ion channels or changes in the cell signaling processes. Some transmembrane receptors are activated by chemicals called ligands. desmarres chalazion forceps
