BIOL 3096: Cell Structure and Function

Learn why lipid-soluble signaling molecules like aldosterone only impact specific target cells. We discuss four theories and reveal that intracellular receptors present only in target cells are the key. This video demystifies the unique mechanism behind aldosterone's selective action.

Discover which biochemical reaction liberates the most energy comparing options like oxidizing sucrose converting ADP to ATP and cellular respiration. This video offers detailed explanations of each reaction's energy output helping you understand their roles in biological systems.

Discover the unique characteristics of the Mammalia class, with a focus on humans. Understand the critical role of molecular oxygen in our survival and the consequences of its absence. Learn how oxygen stands out among other vital factors like food, water, and nitrogen.

Discover the dynamic nature of the cell's lipid bilayer. Delve into the roles of unsaturated and saturated phospholipids in membrane fluidity. Understand temperature's influence on this vital cellular component.

Nucleic acids, comprising DNA and RNA, are vital biomolecules encoding genetic information. We explore the structure and components of their monomers, nucleotides, emphasizing the role of nitrogenous bases and the significance of polynucleotide chains in storing genetic data.

Explore the spectrum of movement in joints, from immovable synarthrotic to freely movable diarthrotic. Understand how these classifications correspond to fibrous, cartilaginous, and synovial joint types.
