Intro to metabolism
metabolism
the totality of an organisms chemical reaction
transforms matter & energy
forms of energy
kinetic energy-energy associated with motion
thermal energy-kinetic energy associated with random movements of atoms or molecules
transfer from one object to another is called heat
potential energy-energy that matter possesses because of its location or structure
chemical energy-potential energy available for release in a chemical reaction
energy is the capacity to cause change and can be used to do work-move matter against opposing forces such as gravity & friction
metabolic pathways
specific molecule altered in series of steps to produce a product
catabolic pathways
release energy by breaking down complex molecules into simpler compounds
bioenergetics
study of how energy flows through living organisms
anabolic pathways
consume energy to build
complex molecules from simpler ones
laws of energy transformation
thermodynamics-study of energy in a collection of matter
1st law-energy can be transferred and transformed but not created or destroyed
the energy of the universe is constant
2nd law-Every energy transfer or transformation increases the entropy of the universe
Entropy is a measure of molecular disorder, or randomness
spontaneous processes occur without energy input they can happen quickly or slowly
free-energy change
the concept can be applied to the chemistry of life's process
free energy is the portion of a system’s energy that can do work when temperature and pressure uniform throughout the system as in a living cell
