You wake up late for NUTR 750, and dash to class without eating breakfast. After class, you head off with your study group for an hour of review, then youâre back to classes straight through from 11:10 AM to 2:00 PM. Your hunger has vanished, so you decide to hit the library for more studying then meet friends at HoCo for âItalian Nightâ at 7 PM. As you walk to HoCo, you realize itâs been 24 hours since you last ate. But youâre not worried, because you know your liver is synthesizing glucose to maintain blood sugar levels for your brain. Please name (a) the top three biochemical substrates that the liver will use for gluconeogenesis, (b) the key regulated enzymes that make hepatic glucose synthesis possible, and (c) the mechanisms by which each enzyme is regulated. (d) Does your fasted state impact each enzymeâs mechanism of regulation, or only certain enzymes? Why or why not - from a biochemical perspective.
