You know ‘em, you love ‘em. They’re the powerhouse of the cell: mitochondria. They produce the ATP molecules that we use to do everything from talk to our friends to run a marathon. In this episode of Crash Course Biology, we’re taking a...

When someone gets a PET scan to detect tumors and how far a cancer has spread, that machine is actually detecting sugar. Because cancer has a sweet tooth, and this phenomenon, called the Warburg effect, may help us develop new cancer...

Paul Andersen describes three main characteristics of life that are conserved in all organisms on the planet. The universal genetic code, the central dogma of biology, and shared metabolic pathways give us details of the original...

Paul Andersen covers the processes of aerobic and anaerobic cellular respiration. He starts with a brief description of the two processes. He then describes the important parts of the mitochondria. He explains how energy is...

Thomas Seyfried, a professor of biology at Boston College, explains that cancer is increasingly prevalent, with over 600,000 people dying annually in the U.S. Traditionally viewed as a genetic disease, Seyfried argues that cancer is...

Creatine Function (1/2): Biosynthesis, Thermodynamic Concerns, and Exercise

This video is part of a series in which we do an overview of metabolism and pathways. Specifically, this video covers the citric acid [Krebs] cycle and the basics of NADH, FADH2, and electron transport.

This video explains what creatine is, how it works in the body, and whether it is safe and effective for increasing athletic performance. It covers topics such as how creatine is synthesized and stored in the body, how it helps provide...

Here, we explore the physiology and metabolic requirements of the myocardium layer of the heart. Also, what would happen if a blood vessel in coronary circulation became occluded?

ATP Synthase: Proton-powered Rotation

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.

The trilogy is finally concluded! And with a bang, no less, as this final stage of cellular respiration is the one that provides the big energy payoff for the cell. Let's learn about how the products of the Citric Acid cycle go on to the...

In this video, we explore the basic properties and functions of red blood cells, also known as erythrocytes.
