M4L1 - Bioenergetics

Energy

This is the capacity of a physical or chemical system to do work

First law of thermodynamics

This stipulates that energy cannot be created or destroyed, only transformed

Second law of thermodynamics

This stipulates that in any spontaneous process, the entropy of an isolated system always increases

Gibbs energy

This is the maximum amount of work a system can do on its surroundings

Enthalpy

This is the work done by a system under constant pressure

Entropy

This is a measure of loss in capacity of a system to do work

Temperature

This is a macroscopic measurement of thermal energy

Work

This is energy transfer that makes atoms move more uniformly

Heat

This is energy transfer that makes atoms move more randomly

Molecular bonds

This has energy which drives chemical reactions

Charge separation

This refers to the flow of hydrogen ions and other ions

Redox

This refers to the flow of electrons between chemical species
