Document Summary
Synthesis of carbohydrates + breaking down of food = catabolic break down. Definition: sum of all chemical reactions in cells. 1985 cdc started tracking data for clinical obesity. Most of diseases in us are influenced by obesity. Metabolic disorders, in order to fix need to understand metabolism. We rely on plants as the foundation of our food chain photosynthesis. Plants produce all food indirectly and directly they feed animals. Photosynthesis: remarkable ability of a plant cell to take co2 oxygen from the atmosphere and convert to carbohydrate and sugar. Using sugars to do work = respiration: very demanding energetic process, sugars + o2 h2o + co2, deriving energy that originally started as sunlight to drive all metabolic path. Amount of co2 in our atmosphere is moderated by plants. We use carbohydrates fixed by plants to drive our energy needs and society"s. Co2 that was used thousands of years ago is now fossil fuels that are used today.
