Quantum Gravity 3d rendered image of a comprehensive exploration of Quantum Gravity theories. String theory, loop quantum gravity (LOG), causal dynamical triangulation, twistor theory, gravitational waves, spacetime, gravity waves, quantum mechanics, quantum entanglement concepts.
After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
