In the Synthesis Cycle of Glutamate, It Is Generally the Case

In the synthesis cycle of glutamate, it is generally the case that

A) neurons convert glutamate to glutamine, while glial cells convert glutamine to glutamate.
B) neurons convert glutamine to glutamate, while glial cells convert glutamate to glutamine.
C) neurons convert glutamine to glutamate, which is then hydrolyzed by glutaminase in the synaptic cleft.
D) glial cells convert glutamine to glutamate which is then recycled into the presynaptic neuron through reuptake.
E) glial cells convert glutamine to glutamate, which is then hydrolyzed by GAD before diffusing away.
