Summary Introduction

To determine: The number of moles of acetylcholine in 15 mL sample of pH of 7.65 when the sample incubated with acetylcholinesterase pH drops to 6.87 .

Introduction:

The splitting of water results in the formation of two ionic species hydrogen ion and hydroxide ion. The hydrogen ions and hydroxide ions are released in equal number when the water is dissociated. The alkalinity or acidity of the solution is determined by the pH (potential of hydrogen) of a solution.

The negative logarithm of the molar ion hydrogen ( H+ ) ion concentration is called pH. It is calculated by the formula pH=log [H+] . The hydrogen ion concentration can be calculated by pH by the formula  [H+]=10pH . The hydrogen ion concentration is calculated by the given pH of the solution. The pH of a solution is in the range of 0 to 14.

The pyruvate dehydrogenase complex catalyzes the oxidative decarboxylation of pyruvate to form acetyl CoA. E₁, E2, and E3 are abbreviations for the enzymes of the complex. Classify the enzyme names, prosthetic groups, and reactions as E1, E2, or E3. E₁ E2 Answer Bank E3 transfer of electrons to FAD and then to NAD+ transfer of acetyl group to coenzyme A formation of hydroxyethyl-TPP hydroxyethyl group transferred to lipoamide thiamine pyrophosphate (TPP) FAD lipoamide dihydrolipoyl transacetylase pyruvate dehydrogenase dihydrolipoyl dehydrogenase
Patients with pyruvate dehydrogenase deficiency show high levels of lactic acid in the blood. However, in some cases, treatment with dichloroacetate (DCA), which inhibits the kinase associated with the pyruvate dehydrogenase complex, lowers lactic acid levels. How does DCA act to stimulate pyruvate dehydrogenase activity? DCA activates pyruvate dehydrogenase kinase. DCA increases phosphorylation levels of pyruvate dehydrogenase. DCA inhibits pyruvate dehydrogenase kinase. ODCA activates pyruvate dehydrogenase phosphatase. What does this suggest about pyruvate dehydrogenase activity in patients who respond to DCA? The pyruvate dehydrogenase complex is active only when phosphorylated by the kinase. The pyruvate dehydrogenase complex is active only in the presence of the kinase. The pyruvate dehydrogenase complex is completely inactive. The pyruvate dehydrogenase complex displays some residual activity.
