Document Summary
The set of chemical reactions needed to sustain life. The set of reactions that produce biological macromolecules and other large molecules needed to sustain life. The set of cellular reactions used to harvest outside energy and convert into a usable form. Chemo = chemistry (oxidation of organic compounds) Plants absorb sunlight to take co2 to form sugars release o2. Primary producers base of food chain. Heterotrophs consume plants for sugars (energy) and carbon (building block of biological macromolecules growth + homeostasis) Reduced compounds have a lot of free energy stored in them harness energy catabolism. The more hydrogens the more reduced. Break-down from large molecules to small molecules. Electrons on compound a goes to another compound b (coenzyme) B was originally oxidized but became reduced when it gained electrons. Must be oxidized in order to gain electrons. Exist in both oxidized and reduced states. Energy storage forms and simultaneously electron storage forms.
