question 13

Multiple Choice

Scientists are attempting to characterize a novel neurotransmitter, neurotran-Y (NTY) , which is synthesized by the enzyme neuro-y-oxidase (NYO) from a precursor, neuro-A. In an experiment they inject artificially high levels of NTY into the pre-synaptic terminal of a cell that releases NTY. Shortly thereafter, they measure the activity of NYO and observe that its activity has been suppressed. The scientists have found evidence for

• A) reuptake.
• B) hydrolyzation.
• C) co-transmission.
• D) feedback inhibition.
