Document Summary

Glucose + 2 adp + 2 nad 2 pyruvate + 2 atp + 2 nadh. Glucose + 2 adp 2 lactate + 2 atp + 2 adp. Bacteria doesn"t have mitochondria, so the rumen microbes do not have oxidative phosphorylation. But they can"t breakdown further to acetyl coa: unsaturated fats go to saturated fats (biohydrogenation, methane and hydrogen are both greenhouse gasses (these aren"t good) Formic gas going to methane is a way to get rid of hydrogens: acetate goes to eventually to make milk fat, propionate goes to make lactose (disaccharide) A high grain diet tends to result in higher propionate. Gluconeogenesis: precursors include: carbon sources for pyruvate. Lactate, most amino acids, propionate, and glycerol: 1st step: pyruvate kinase catalyzes pep to pyruvate (adp atp aka gain 1. Delta g is very negative, so it"s an irreversible step. Two enzymes that get around that step is: Pep carboxykinase (adding phosphate group: all the other steps are reversible.
