Document Summary
Metabolism all of the reactions inside a living organism: reaction the movement of energy and/or atoms between molecules, requires energy. Cannot be created or be destroyed: first law of thermodynamics. Almost all energy on earth comes from the sun: some from the earth itself (geothermal) Energy is transferred in living cells using adenosine triphosphate (atp: high energy bonds attach the phosphate groups, breaking them releases a lot of energy, created bonds of stored energy. Used energy leaves in the form of heat. Requires enzymes that aids the reactions and move energy/atoms (like o o carbon) Co2 + h2o (driven by sunlight) reacts to form glucose and 02. Harvest carbon dioxide from the air along with water. Requires chlorophyll: green pigment in cells, harvests energy, found in chloroplasts. Energy and carbon for all living things is harvested by photosynthesis: respiration. Releases energy stored in organic molecules (like glucose) to make atp: glucose + o2 reacts to form co2 and atp.
