BIOL 71008: Biology of Microorganisms

Explore the crucial concept of biodiversity and its significance. Learn about the various threats it faces, from pollution to habitat destruction. Emphasize the paramount threat: habitat alterations and their implications.

Explore active and passive transport and understand how ion pumps and phagocytosis fit in. Discover endocytosis as an active transport where cells engulf particles. Differentiate between active transport mechanisms and passive methods like facilitated diffusion.

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.

Discover which metabolic pathway is the heavyweight champion of ATP production. We'll evaluate contenders like lactic acid fermentation, the Krebs cycle, and more to determine the top ATP generator.

Explore the intricate components of the endomembrane system within a cell. Identify which structures belong to this system and which do not, with a specific focus on the unique role of the chloroplast.

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.
