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 you’re 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
“Italian Night” at 7 PM. As you walk to HoCo, you realize it’s been
24 hours since you last ate. But you’re 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 enzyme’s mechanism of regulation, or only
certain enzymes? Why or why not – from a biochemical
perspective.
