How are relay molecules inactivated
WebCommunication of information between neurons is accomplished by movement of chemicals across a small gap called the synapse. Chemicals, called neurotransmitters, are released from one neuron at the presynaptic nerve terminal. Neurotransmitters then cross the synapse where they may be accepted by the next neuron at a specialized site called a ... WebCancer Midterm. 5.0 (1 review) GPCR activate G-protein by reducing the strength of GDP binding, allowing GDP to dissociate and GTP, which is present at a much higher concentrations to bind. How do you suppose the activity of a G protein would be affected by a mutation that caused its affinity for GDP to be reduced without significantly changing ...
