Paul Andersen explains the structure, function and importance of adenosine triphosphate (ATP). He begins by describing the specific structure of the molecule and its three main parts: adenine, ribose sugar, and phosphate groups. He...

Table of Contents: 00:00 Intro 0:40 Some Examples of ATP Uses in Cell Processes 1:14 What is ATP? 1:52 How do we get ATP? 3:05 How does ATP work? Note: We received an excellent comment in an older video (about cellular respiration) that...

In which Hank does some push ups for science and describes the "economy" of cellular respiration and the various processes whereby our bodies create energy in the form of ATP.

Paul Andersen explains the importance role of coupled reactions in biology. He starts by explaining how the power of a river can be harnessed by a water mill to grind grains. He describes the importance of ATP and how it is used within...

Paul Andersen attempts to explain Gibbs Free Energy. He begins by using three spontaneous reactions to explain how a change in enthalpy, entropy and temperature can affect the free energy of a system. He then applies this concept to...

In this lecture, I talk about Cellular respiration, which consists of Glycolysis, the Krebs Cycle and the Electron Transport Chain.



I deal with how Glucose is broken down and how ATP is made. Since energy is important for all...

Plant Physiology and Chemistry Set: 2. This clip provides an in-depth look at the details of the light-dependent Biochemical reactions of photosynthesis,

In this video, we discuss all steps of excitation-contraction coupling in skeletal muscle from events on the motor neuron axon all the way through cross-bridge cycling between actin and myosin.

Part 2 of 2 of excitation-contraction coupling | In this video, we discuss excitation-contraction coupling from opening of calcium channels in the sarcoplasmic reticulum (SR) all the way through cross-bridge cycling between actin and...

Have you ever wondered what creatine is and how it works, then this video is for you. I'll explain the biology behind creatine in the context of how muscle contraction happens. Enjoy!
