BIOL 1107 Lecture Notes - Lecture 8: Kinetic Energy, Thermodynamics, Cellular Respiration
Document Summary
The totality of an organism"s chemical reactions. It is an elaborate road map of the chemical reactions in that cell. Metabolic pathways alter molecules in a series that are each catalyzed by. Catabolic and anabolic pathways are coupled. a specific enzyme. Bioenergetics is the study of how organisms manage their energy resources. Energy is the capacity to do work- to move matter against opposing forces. Energy can be converted from one form to another. Energy is transferred or transformed but is not created or destroyed. Energy transformation or transfer increases the entropy of the. Entropy- quantity used as a measure of disorder, or randomness. The more random a collection of matter, the greater its entropy. While order can increase locally, there is an unstoppable trend toward randomization of the universe. Ordered forms of energy are converted at least partly to heat. The quantity of energy is constant, but the quality is not.
