Initially, in a glutamatergic synapse, the neurotransmitter glutamate is released from the neurons and is taken up into the synaptic cleft. Glutamate residing in the synapse must be rapidly removed in one of three ways: 1. uptake into the postsynaptic compartment, 2. re-uptake into the presynaptic compartment, or WebSep 1, 2009 · Glutamine enters the TCA cycle by being converted to glutamate and subsequently to α-ketoglutarate (α-KG). α-KG is a TCA intermediate but cannot enter cells.
