Electrochemical Gradient
In this video Paul Andersen explains how the electrochemical gradient is a combination of the chemical and electrical gradient of ions. As ions move across a membrane the potential change creates a hidden force that isn't always apparent.

Electric Field of Parallel Plates
In this video Paul Andersen explains how the electric field between oppositely and equally charged plates is uniform as long as you are far from the edge. The strength of the electric field can be determined by either the charge of the...

The Action Potential
In this video Paul Andersen details the action potential in neurons. The resting potential of a neuron (-70mV) is maintained through differences in concentration and permeability of Na, K, and Cl ions. A graded potential is created as...

Neutralization Reaction
In a neutralization reaction (or acid-base reaction) a proton is transferred from the Brinsted--Lowry acid to the Brinsted--Lowry base. Water is amphoteric and so it can serve as either an acid or a base in a neutralization reaction. The...

Alkyne Reactions Tautomerization - Crash Course Organic Chemistry
Carbon-carbon double bonds are pretty common in nature, but triple bonds between carbons, called alkynes, are not. When alkynes do pop up in nature, it’s usually in a compound that’s toxic to humans, however, we can synthesize alkynes...
