BIOS 208: Fundamentals of Cell Biology

Dive into the biochemistry of haemoglobin, a pivotal protein in red blood cells. We assess key statements about its structure and function, clarifying common misconceptions.

Discover how humans adapt to cold environments through thermoregulation processes. Understand the body's heat conservation and generation mechanisms. Learn why certain physiological responses occur in cold conditions.

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

Explore the pivotal role of enhancers in gene expression as we dissect their function and interaction with transcription factors. Gain insights into how they crucially influence the transcriptional control of genes.

Explore the processes behind ATP synthesis during oxidative phosphorylation. Learn the pivotal role of the proton gradient in energizing ATP synthase. Visualize the interplay of cellular components producing the ATP symphony.

Explore what makes each element unique by focusing on the atomic components: protons neutrons and electrons. Learn why the number of protons known as the atomic number is the defining characteristic for each element's properties. Understand how protons set elements apart even as neutrons and electrons also play important roles.
