BIOL 201: Anatomy & Physiology I

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.

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.

This video provides a comprehensive explanation of mucous and serous membranes, defining their characteristics and addressing statements about their epithelial types, functions, and exceptions.

Explore the underlying causes of muscle fatigue and the crucial role of lactic acid. Understand the impact of ATP depletion and anaerobic metabolism on muscle performance. Gain insights into planning effective exercise and recovery strategies.

Discover the role of Okazaki fragments in DNA replication and the importance of DNA Ligase in ensuring their correct joining. Learn how a malfunction in this enzyme might disrupt the formation of continuous DNA strands on the lagging strand.

This data-driven video examines the difference in nucleotide replication rates between prokaryotes and eukaryotes, providing insights into the factors affecting their speed. It concludes that prokaryotes outpace eukaryotes, replicating nucleotides approximately ten times faster, and explores the contributing factors behind this difference.
