So I had a biochemistry exam this passing Friday. It had eleven (11) questions–no multiple choice–that had to be completed in fifty (50) minutes. We were required to know: Spoiler (1) Glycolysis . . . . . . Ten (10) steps; breaks glucose into pyruvate. (2) Gluconeogenesis . . . . . Eleven (11) steps; converts pyruvate back into glucose (3) Lactate fermentation . . . . . One (1) step; reversible; vertebrates; converts pyruvate into lactate. (4) Ethanol fermentation . . . . . Two (2) steps; irreversible; yeasts and other organisms; converts pyruvate into ethanol. (5) Citric Acid cycle . . . . . One (1) preliminary step (turn pyruvate into acetyl-C0A) and eight (8) steps that cycle repeatedly; generates energy (I.e. NADH, FADH2, GTP) (6) Electron Transport Chain . . . . . Series of reactions with increasing reduction [H] potential; generates MORE energy (i.e. ATP via ATP synthase after pH and voltage gradient materializes between mitochondrial matrix and inter-membrane space from H+ dumping.). (7) Breakdown of triacylglycerols and conversion of free fatty acids into acyl-CoA. (8) Beta oxidation . . . . . Four (4) steps; converts acyl-CoA into acetyl-CoA (each generates more energy with proper processing) (9) Photosynthesis . . . . . Photosystems II & I, including Calvin cycle when there's no light. Yeah. There was a lot, but I performed. To help myself get ready, all of Thursday evening was spent generating notes like these... I'd list my other ones, but they're too sloppy for viewing. T'was a very accelerated last week it was.
How you can revise from this is beyond me, but I'd like to look at your citric acid cycle one. Do you have a higher res picture of it? I can't make out a lot of it.
I'll probably just redraw the general reaction pathways for glucose. Without rushing I'd be able to do a better job keeping things cleaner and preventing them from resembling Picasso's Guernica.
