Document Summary
Chapter 6: energy flow in the life of a cell. Matter: anything that takes up space and has mass; the physical material of the universe. Work: the transfer of energy to an object. Two types of energy: potential energy energy stored in matter because of its position or location. in biological systems is stored in chemical bonds, kinetic energy the energy of motion (light, heat, electricity, movement of photons, molecules, particles. Energy transfer by organisms is subject to two laws of thermodynamics: 1st law of thermodynamics: energy can be transferred and transformed, but it cannot be created or destroyed (i. e. , the energy of the universe is constant). Law of conservation of energy : 2nd law of thermodynamics: every energy transfer or transformation makes the universe more disordered (i. e. , every process increases entropy at the cost of useful energy) Energy conversions (transfers) happen at the cost of useful energy (f. 6. 2)
