These days, we don't have to worry too much about meeting an early demise from ulcers, breaks in the stomach lining that could be fatal back in the early 1900s. This is because we have medicines to treat them, like proton pump...

You might think a self regulating factory sounds pretty unbelievable, but that’s pretty much exactly how our bodies work! Our bodies are full of regulatory mechanisms that keep all the organic molecules we need to live in balance. In...

Already watched the Amoeba Sisters first video on enzymes and ready to explore a little more? In this video, the Amoeba Sisters cover a few examples of enzymes in the human body before emphasizing that enzymes are found in all the...

Some people take aspirin or ibuprofen to treat everyday aches and pains, but how exactly do the different classes of pain relievers work? Learn about the basic physiology of how humans experience pain, and the mechanics of the medicines...

The Amoeba Sisters explain enzymes and how they interact with their substrates. Vocabulary covered includes active site, induced fit, coenzyme, and cofactor. Also the importance of ideal pH and temperatures for enzymes are discussed.

Paul Andersen explains how enzymes are used to break down substrates. The correct shape of the active site allows a key/lock fit between the enzyme and the substrate. The enzyme catalase is used to break down hydrogen peroxide. The...
