ANAT 222: Cell Biology

Discover the differences between hydrocarbons and other organic molecules. While hydrocarbons contain only carbon and hydrogen, other organic molecules integrate more elements and functional groups. This distinction leads to diverse chemical properties and vital biological functions.

Learn about the critical roles of the epiglottis and glottis in our respiratory and digestive systems. Understand how the epiglottis acts as a protective gate during swallowing, while the glottis facilitates sound production. Together, they ensure safe breathing and swallowing.

Understand the essence of controlled experiments and the significance of control groups. Unpack the common misconceptions associated with experimental design. Grasp the key factors that make an experiment truly controlled.

Uncover the intricacies of adaptive radiation, the rapid diversification of species into new ecological niches. Understand factors that drive this phenomenon and how genetic drift stands as an exception. Learn the role of evolutionary innovations and interactions in species divergence.

Deepen your understanding of glycolysis, a foundational cellular metabolism process. Grasp how glucose transforms into pyruvate or lactate, based on the presence of oxygen. A clear insight into this process aids in exercise science and disease research.

In this video, we explore virus structure, specifically focusing on glycoproteins that extend from the virus's surface. Four statements related to virus structure are examined for accuracy, including the presence of a viral membrane, the composition of capsomeres, the genetic material within viruses, and the role of glycoproteins in virus attachment to host cells. The video highlights the importance of glycoproteins in facilitating virus attachment to host cells, ultimately marking the initiatio
