Explanation:

2-deoxyglucose poison has its effects during glycolysis, which only produces 2 ATP, while Cyanide takes place during ETC which produces 34. If given the 2-deoxyglucose poison this would stunt the rest of the process very early on, so much so that no ATP could have been produced. So the ATP concentration would have decreased if given the other poison.

zaharov [31]

Answer:

C. a pre-synaptic neuron involved in egg-laying

Explanation:

Serotonin (5-HT) is a neurotransmitter, i.e., a molecule that binds to specific receptors and thus transmits signals from one pre-synaptic neuron to another target cell. In humans, serotonin is involved in many physiological functions including sleep, mood, emotions, appetite, digestion, etc. Moreover, <em>Caenorhabditis elegans</em> is a model organism widely used in neuroscience research in order to understand neuromodulation at the level of individual neurons. In <em>C. elegans,</em> serotonin modifies behavior by regulating neuronal excitability and synaptic efficiency. Moreover, also in <em>C. elegans,</em> it has been shown that serotonin induces egg-laying and also provides a feedback regulatory mechanism by inhibiting the activity of the pre-synaptic neurons that release it. In consequence, in this case, it is expected that serotonin rescues the loss of function of serotonin receptors required for egg-laying by providing a regulatory feedback loop that contributes to serotonin adaptation.
