Alright, lemme try to explain something I don't have a firm grasp on. Recently we've been talking about the digestive system and cell respiration, and I've been nothing short of confused. But here's my attempt.
Our digestive system is just kinda a giant tube inside of us, from the mouth to the esophagus to the stomach to the small and then large intestine and then the colon and rectum to be pooped out. Yay. Throughout this system there are various enzymes that break down carbohydrates, proteins, fats, and nucleic acids, and most of these enzymes come from the liver. Salivary amylase is one exception, but proteases, nucleotidases, and bile are all secreted by the liver, are stored in the gall bladder, and move into the duodenum of the small intestine, where most everything is digested. Absorption occurs throughout the intestines and colon.
Cell respiration, on the other hand, is not so straightforward. But the basics?
C6H12O6+6O2-->6CO2+6H2O+32ATP
That happens through a series of chemical reactions, involving changing the 6 carbon to two 3 carbons to a 4 carbon to CO2 and then some electron releases, which are where the fun happens. The electron transport chain produces most of the ATP, because the electrons are passed from protein to protein, releasing and absorbing H+ and creating energy and water. I'm still a little foggy on the specifics, but that's the gist of it. Expect a more detailed explanation later?
Well, that's all I got for now (besides a Jell-O lab with some enzymes and a cell respiration lab with yeast that was a total failure).
Bye!
