Gibbs Free Energy
Paul Andersen attempts to explain Gibbs Free Energy. He begins by using three spontaneous reactions to explain how a change in enthalpy, entropy and temperature can affect the free energy of a system. He then applies this concept to...
Crash Course
ATP & Respiration: Crash Course Biology
In which Hank does some push ups for science and describes the "economy" of cellular respiration and the various processes whereby our bodies create energy in the form of ATP.
Bozeman Science
ATP: Adenosine Triphosphate
Paul Andersen explains the structure, function and importance of adenosine triphosphate (ATP). He begins by describing the specific structure of the molecule and its three main parts: adenine, ribose sugar, and phosphate groups. He...

Khan Academy: Sodium Potassium Pump
This video explains how a sodium-potassium pump can maintain a voltage gradient across a cell or neuron's membrane. The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. [13:52]

Khan Academy: How Tropomyosin and Troponin Regulate Muscle Contraction
This video describes how calcium ion concentration dictates whether a muscle contracts or not. [9:22]
Khan Academy
Khan Academy: Uniporters, Symporters and Antiporters
Uniporters, symporters, and antiporters are proteins that are used in the transport of substances across a cell membrane. This video describes how each of these works in the transport process. [7:13]
