Imagine That a Hypothetical Neurotransmitter, Neurotran-X (NTX), Is Synthesized from Two

question 17

Multiple Choice

Imagine that a hypothetical neurotransmitter, neurotran-X (NTX) , is synthesized from two ingredients, neuro-A and tran-B. An enzyme, neurotranoxylase (NTO) , is responsible for producing neurotran-X from the two ingredients. If the rate of synthesis of NTX is controlled through feedback inhibition, you would expect to observe experimentally

• A) increasing levels of NTO will lead to increased levels of NTX.
• B) reducing levels of neuro-A will reduce levels of NTX.
• C) increasing levels of NTX will lead to reduced activity of NTO.
• D) reducing levels of neuro-A will lead to reduced activity of NTO.
• E) reducing levels of NTX will lead to reduced activity of NTO.
