BIOL 201 Chapter Notes - Chapter 5: Thermodynamics, Living Systems, Cellular Respiration
Document Summary
Nearly every process vital to life depends on energy from the sun. Solar energy + other factors is responsible for movements of air and water. Less than 1% of the solar energy is captured by cells of plants and other. Living organisms change energy from one form to another that set patterns of climate photosynthetic organisms. Energy is defined as the capacity to do work. Energy can be changed from one form to another but cannot be. In all energy exchanges/conversions, if no energy leaves or enters the system under study, the potential energy of the final state will always be than the potential energy in intial. A ball will roll down a hill but never up. In many cases, an exergonic reaction is also an exothermic o o o o reaction (negative delta h) Must be an input of energy to proceed. Another factor that determines direction of a process.
