BIOL 110: General Biology II

Explore the vital roles of pharyngeal slits in lancelets and tunicates. Learn how these clefts aid in filter-feeding, capturing food particles, and evolve through different life stages.

Discover the intricacies of catabolism and the role of the citric acid cycle in CO2 release. Understand how glycolysis leads to the production of pyruvate, ATP, and NADH. Gain clarity on how our body processes and expels carbon dioxide during cellular metabolism.

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.

Explore the distinct characteristics of muscle tissues and their functions. Understand the differences between skeletal, cardiac, and smooth muscles. Get insights into the anatomy of striations, cell shapes, and nuclei.

Learn about the anatomy of the tibia, one of the lower leg bones, and discover how it's connected to the fibula through the interosseous membrane. Find out the correct answer regarding the tibia's structure and connections.
