Short answer questions. You must show work indicating production or consumption of molecules such asATP or NADH in the various pathways involved in these questions.Consider that a molecule of alanine can be converted to pyruvate by an oxidation reaction that producesone NADH. If the liver is to make a molecule of glucose from alanine, how many molecules of alanine are required?How many ATP equivalents are required?

Sure, let's break down the process step by step:1. Conversion of Alanine to Pyruvate: Alanine is…

For a given acid HA, it was determined that at pH 6.0 the concentration of the conjugate base [A] was 0.075 M and the acid [HA] was 0.025 M. What percent of this acid is ionized at pH 6.0? What is the pKa of this acid? What pH would this acid be 50% lonized?
Glucose is the preferred energy source of the brain, Why?
Which statements describe electron transport chain events? Two electrons pass between cytochromes through a series of redox reactions. Citrate metabolism results in the formation of one FADH2 and three NADH. NADH releases two hydrogen ions and donates two electrons to coenzyme Q. ATP synthase uses the energy from the redox reactions to generate ATP.
Describeenergy consumed vs released in reactions. Differentiate between endergonic vs exergonic reactions, anabolism vs catabolism, and coupled reactions.
Trypanosomes living in the bloodstream obtain all their free energy from glycolysis. They take up glucose from the host’s blood and excrete pyruvate as a waste product. In this part of their life cycle, trypanosomes do not carry out any oxidative phosphorylation, but they do use another oxygen-dependent pathway, which is absent in mammals, to oxidize NADH. Would this pathway be necessary if the trypanosome excreted lactate rather than pyruvate? Explain.
