BIOL 150: Organismal and Ecological Biology

Unlock the secrets of ATP's essential role in powering life's processes. Discover why ATP is a specialized molecule that stores energy for your cells. Learn how to differentiate between common misconceptions and the real function of ATP.

Explore the definitions of tissue, organ, and organ system. Understand the distinctions and interconnectedness between these components. Get an overview of the human body's eleven major organ systems and their functions.

Explore the incredible process of cell differentiation and how cells become specialized through the production of tissue-specific proteins. Witness the unique roles of muscle cells and neurons as they create essential proteins for their functions. Uncover the symphonic beauty of life's complexity through this fascinating biological journey.

Explore the concept of semiconservative DNA replication, where each new DNA molecule retains one original strand. Understand the significance of this mechanism in ensuring accurate genetic information transfer across cell generations.

Discover the mechanics of voltage-gated Na+ channels and their role in neuron activity. This video breaks down key neuronal terms like resting potential and threshold to explain precisely when these channels open. You'll come away understanding that voltage-gated Na+ channels open at the threshold state initiating an action potential.
