Mash - check out page 155 of FA: Enzymes required for gluconeogenesis are found only in the kidney, intestinal epithelium and kidney. I think that is what they meant in the question (where does it actually happen..not where do the substrates come from)....although it wasn't clearly stated!

Why not glycerol from triglyceride breakdown?

Triglyceride breakdown happens when there is hypoglycemia or to increase in fuel supply , glycerol joins the glycolytic pathway twords TCA cycle that form the A-COA before entering the cycle so the direction is opposit the gluconeogenesis.

If muscle tissue needs glucose, it has send all G6P back to live to form glucose then come back to muscle and used as energy

Everything indirectly contribute to the glucose level !!!

Absolutely. And if my old biochem doesn't betray me, there are even some glycogen particles (those at the «ramification points» of the big molecule) that can be converted to glucose. Quite uncommon, yes, but they're some of those exceptions that can make us think twice at options like a) and c). The goal of the question, however, was clearly to find out where the gluconeog enzymes were... intestine. How clever. grin
