Chapter 8.1 Flashcards
A metabolic pathway that releases energy by breaking down complex molecules to simpler molecules.
Catabolic Pathway
A metabolic pathway that consumes energy to synthesize a complex molecule from simpler molecules
Anabolic Pathway
(1) The overall flow and transformation of energy in an organism. (2) The study of how energy flows through organisms.
Bioenergetics
The capacity to cause change, especially to do work (to move matter against an opposing force).
Energy
The energy associated with the relative motion of objects. Moving matter can perform work by imparting motion to other matter.
Kinetic Energy
Kinetic energy due to the random motion of atoms and molecules; energy in its most random form.
Thermal Energy
The total amount of kinetic energy due to the random motion of atoms or molecules in a body of matter; also called thermal energy. Heat is energy in its most random form.
Heat
The energy that matter possesses as a result of its location or spatial arrangement (structure).
Potential Energy
Energy available in molecules for release in a chemical reaction; a form of potential energy.
Chemical Energy
The study of energy transformations that occur in a collection of matter
Thermodynamics
The principle of conservation of energy: Energy can be transferred and transformed, but it cannot be created or destroyed.
1st law of thermodynamics
The principle stating that every energy transfer or transformation increases the entropy of the universe. Usable forms of energy are at least partly converted to heat.
2nd law of thermodynamics
