Document Summary
Aerobic mitochondria dependent respiration is the reverse of photosynthesis. Photosynthesis oxidizes water to o2: requires energy. Water (light energy) oxygen leaves nadp+ and adp become atp and. Nadph co2 + h2o enters the chloroplast becomes carbohydrate (containing high- energy electrons) Mitochondrial respiration reduces o2 to water: releases energy. One glucose = 36 molecules of atp. Light reaction vs. dark reaction (light independent) Usually depicted as oval, double membraned organelles, mitochondria undergo rounds of fusion and fission and their shape can change to be considered tubular. Cristae are the skeleton inside the mitochondria. Mitochondria undergo frequent fusion and fission, constantly coming together, then breaking apart again later. Between cristae is an intermembrane region (don"t call it space) Matrix is the inside of the mitochondria. Outer mitochondrial membrane (omm: high lipid, low protein, contains many enzymes with diverse metabolic functions, porins. When open, membrane is freely permeable (eg: to atp)
