The chemical reactions and pathways involving glucose, the aldohexose gluco-hexose. D-glucose is dextrorotatory and is sometimes known as dextrose; it is an important source of energy for living organisms and is found free as well as combined in homo- and hetero-oligosaccharides and polysaccharides [goid 6006] [evidence IEA]; The cascade of processes by which a signal interacts with a receptor, causing a change in the level or activity of a second messenger or other downstream target, and ultimately effecting a change in the functioning of the cell [goid 7165] [evidence IEA]; The series of molecular signals generated as a consequence of a G-protein coupled receptor binding to its physiological ligand, followed by modulation of a nucleotide cyclase activity and a subsequent change in the concentration of a cyclic nucleotide [goid 7187] [pmid 1317848] [evidence TAS]; The series of molecular signals generated as a consequence of a G-protein coupled receptor binding to its physiological ligand, followed by inhibition of adenylyl cyclase and a subsequent decrease in the concentration of cyclic AMP [goid 7193] [pmid 1321422] [evidence TAS]; The specific movement from place to place of an organism in response to external or internal stimuli. Locomotion of a whole organism in a manner dependent upon some combination of that organism's internal state and external conditions [goid 7626] [evidence IEA]; Behavior associated with the intake of food [goid 7631] [evidence IEA]; The process that modulates the force with which blood travels through the circulatory system. The process is controlled by a balance of processes that increase pressure and decrease pressure [goid 8217] [evidence IEA]; The series of events required for an organism to receive a painful stimulus, convert it to a molecular signal, and recognize and characterize the signal. Pain is medically defined as the physical sensation of discomfort or distress caused by injury or illness, so can hence be described as a harmful stimulus which signals current (or impending) tissue damage. Pain may come from extremes of temperature, mechanical damage, electricity or from noxious chemical substances [goid 19233] [evidence IEA]; Any process that modulates the frequency, rate or extent of growth of the body of an organism so that it reaches its usual body size [goid 40014] [evidence IEA]
