BIOL 105: Parasites, Pathogens, and Pandemics: Infectious Disease and Society

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 cell biology, the "driving ion" is a pivotal concept. It refers to ions moving from areas of high to low concentration, generating energy for various cellular transport processes. This gradient is crucial for nutrient uptake and waste elimination. Multiple processes involve a driving ion, including facilitated diffusion, symport transport, primary active transport pumps, and cotransport. Facilitated diffusion aids molecule movement along their gradient, while symport moves multiple substance

Explore the crucial role of red marrow in producing vital blood cells and maintaining the circulatory and immune systems. Learn why bones are essential for blood cell production and understand why other options are incorrect.

Discover the critical role iodide ions play in regulating metabolism through their involvement in thyroid hormones. Learn how active transport enables the movement of these ions in the body, requiring ATP energy. Uncover common sources of iodide ions and their importance in medical applications.

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.
