Explain the difference between glycolysis, gluconeogenesis, glycogenolysis, and glycogen synthesis. Please note where each one occurs

In gluconeogenesis, what are the precursors of glucose? Select all that apply. lactate amino acids glycogen glycerol fatty acids

Can you please pick the right answer in each parentheses (a) to (e)? Coenzymes are nonprotein compounds that are required for the activity of certain enzymes.  One critical coenzyme central to metabolism is NAD+.  In fact it is one of 5 coenzymes required by (a)< "pyruvate dehyrogenase" vs "citrate synthase" > , the critical enzyme for producing Acetyl-CoA.  NAD+ is synthesized from  (b)< "niacin (vitamin B3)" vs "acetate" > as was discovered to be critical for health by two American scientists, (c)<"Joseph Goldberger and Conrad Elvehjem" vs "Linus Pauling and Eric Lander"> , in the early 20th century.  Dietary lack of this critical molecule produces pellagra, characterized by the following symptoms: (d)<"skin inflammation, dementia, diarrhea" vs "chorea-like movement">.  People with these problems were found in parts of the U.S. where diets lacked vegetables and consisted principally of corn.  Interestingly, soaking the corn  in (e)<"salt water" vs…
