Active Transport: Moving Substances Against Concentration Gradient
This video explains the concept of active transport, which is the movement of substances from a more diluted concentration to a more concentrated concentration against a concentration gradient. The video provides examples of active...

Neural Conduction, Action Potential, and Synaptic Transmission
We have probably heard that neurons are the cells that transmit information around the body. But how does this work? Is it actual electricity? Like from the wall socket? What is a synapse? What happens there, in between one neuron and...

Factors Affecting Diffusion and Impact on Organisms
This video discusses the concept of diffusion in biology, with a focus on what affects the rate of diffusion and its impact on organisms. The video explains that the rate of diffusion is affected by the concentration gradient,...

Water and Diffusion - The Chemistry of Life
In this section, I talk about the properties of water, and what makes it unique. I talk about hydrogen bonds that result from the polar nature of water and why ice floats.
I also deal with diffusion and go into the 3 factors that affect...

BASICS of the Electron Transport Chain & Oxidative Phosphorylation
In this video, we explore how NADH and FADH2 feed into and power the electron transport chain (respiratory chain) which is coupled with ATP synthesis.

Graded Potentials, EPSPs, IPSPs, & Summation
In this video, we will discuss the purpose of graded potentials, EPSPs, and IPSPs; and how the summation of all graded potentials by the soma dictates whether an action potential occurs.

Factors that Affect Diffusion Rate
In this video, we will discuss four factors that affect the rate of diffusion: molecular weight, concentration gradient, surface area-volume ratio, and the temperature.

Gas Exchange In Different Animals
Respiration is carried out by all living things. Animals need oxygen to carry out aerobic respiration and they need to get rid of the waste product called carbon dioxide. This is called gas exchange. Swapping one gas for another. Animals...

Structure of the Cell Membrane - Active and Passive Transport
What is it that separates what's inside a cell from what's outside of a cell? Why, that's the cell membrane. What's it made out of? How does it work? How do molecules get in and out of the cell? These are super-important concepts! Let's...

BIOLOGY - Cells - Active Transport
In the first part of this video we looked at diffusion to move gases and osmosis for the movement of water, from high concentration to low concentration down their concentration gradient. Active transport works in the opposite direction;...

BIOLOGY - Cells - Diffusion and Osmosis
In this video we are going to discover how cells take in useful substances and remove waste using three methods of transportation: diffusion, osmosis and then in the second part we will look at active transport. The exchange of materials...
