BIOL 40503: Basic Biochemistry

Explore the groundbreaking heterotroph hypothesis by Alexander Oparin. This video outlines how the first organisms likely consumed pre-existing organic matter reshaping how we think about the origins of life and evolution

Explore the fascinating process of protein digestion, debunking misconceptions about where it starts. Discover the roles of enzymes like pepsin and HCl in breaking down proteins in the stomach.

Explore the effects of isotonic, hypertonic, and hypotonic solutions on plant and animal cells. Understand water movement, solute concentration dynamics, and the resulting cellular changes, including turgidity in plants and crenation or lysis in animals.

In this video we explore the unique characteristics that set animals apart from other organisms. We evaluate options like gastrulation multicellularity sexual reproduction and flagellated sperm. Conclusively we identify gastrulation as a truly unique process in animal embryonic development.

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 intricacies of muscle contraction and the pivotal role played by elements like Calcium, Sodium, Potassium, and Chloride. Learn how Calcium directly triggers contraction by interacting with troponin and actin filaments. A thorough breakdown of each element's unique contribution to our body's movement.
