Document Summary

Chapter 6: energy flow in the life of a cell. Work: in turn, is the transfer of energy to an object, causing the object to move. Chemical energy: muscular work is powered by this; which is energy available in the bonds of molecules. Mole(cid:272)ules that p(cid:396)ovide this (cid:272)he(cid:373)i(cid:272)al e(cid:374)e(cid:396)g(cid:455) a(cid:396)e sto(cid:396)ed i(cid:374) the (cid:272)ells of the (cid:396)u(cid:374)(cid:374)e(cid:396)s" bodies. Cells utilize specialized molecules such as atp to accept, briefly store, and transfer energy from one chemical reaction to the next. Includes the chemical energy available in biological molecules and other molecules. Includes radiant energy, heat or thermal energy (motion of molecules or atoms), electrical charge (the flow of charged particles). Under the right conditions, kinetic energy can be transferred into potential energy. The laws of thermodynamics describes the basic properties of energy. States that energy can be created not destroyed by ordinary processes. (nuclear reactions, in which matter is converted into energy) Closed system: energy can neither enter nor leave.
