Join the Amoeba Sisters as they explore the action potential. This video discusses resting membrane potential before going into the phases of the action potential including vocabulary such as depolarization, repolarization, and...

Paul Andersen begins this podcast with a discussion of brain lateralization and gives a brief demonstration of tests that were performed on split-brain individuals. He then discusses the major parts of a neuron and explains how action...

Paul Andersen describes how cells move materials across the cell membrane. All movement can be classified as passive or active. Passive transport, like diffusion, requires no energy as particles move along their gradient. Active...

Action Potential Physiology (FULL VIDEO)

In this video, I go through the details of the 4 types of proteins in the membrane of neurons: The passive/leakage ion channels, Sodium Potassium pump, Voltage-gated ion channels and ligand-gated ion channels

Describes the mechanism of transport of water and minerals in plants. Explain movement of food from leaves to other plant parts.

In this video, we will discuss the differences between primary and secondary active transport by looking at a few specific transport mechanisms.
