Acritical reaction in the production of energy to do work or drive chemical reactions in biological systems is the hydrolysis of adenosine triphosphate, atp, to adenosine diphosphate, adp, as described by the reaction atp(aq)+h2o(l)⟶adp(aq)+hpo2−4(aq) for which δ∘rxn=−30.5 kj/mol at 37.0 °c and ph 7.0. calculate the value of δ in a biological cell in which [atp]=5.0 mm, [adp]=0.90 mm, and [hpo2−4]=5.0 mm.

Let the ed50 of a recreational drug be defined as the amount required for 50% of a test group to feel high or get a buzz. if the ed50 value of ethanol is 470 mg/kg body mass, what dose would a 70 kg party goer need to quickly consume in order to have a 50% chance of getting a buzz? 235 mg 470 mg 32,900 mg 35,000,000 mg
