Document Summary
Metabolism = using sources from environment to build up macromolecules: glycolysis = transferring energy from glucose, catabolic = break down, anabolic = build up. Complementary processes of photosynthesis and respiration: photosynthetic organism phototrophs use energy from sunlight to fix co2 from the atmosphere and build up sugars, humans chemotrophs-take up these organic compounds like sugar and form it into energy. Can then burn those molecules to produce energy (atp), but a lot stay as intermediates b. ii. Energy derived from breaking down our food is stored in atp b. ii. 1. We use atp to build up sugars (glycogen) and fats (triglycerides) to store energy at times of surplus b. ii. 2. Protein can also be broken down to make atp. Breakdown of sugar: cells oxidize sugars in a step-wise fashion a. i. Cell metabolism releases energy in steps and harvest it in activated carrier molecules such as atp and nadh.
