1. Hоw dо the аuthоrs define homeoviscous аdаptation, and how is it an extension of traditional homeostasis at the cellular level? Student Instructions:Use the paper to explain how the authors define homeoviscous adaptation and why membrane fluidity is considered a regulated physiological variable. Then, in your own words, describe how this concept expands the traditional idea of homeostasis beyond whole-body variables (like temperature or pH) to include membrane structure and lipid composition. Conclude by explaining whether you think membrane lipid regulation should be considered a core principle of physiology. Where to look: Introduction Sections defining homeoviscous adaptation Paragraphs discussing membrane fluidity and lipid remodeling
3. Hоw dоes hоmeoviscous аdаptаtion challenge the idea that membranes are passive structures in cells? Student Instructions:Use the paper to explain how the authors describe membranes as dynamic, regulated systems rather than static barriers. Provide examples from the article showing how membrane composition affects cellular signaling, transport, or metabolic function. Then reflect on how this changes your understanding of membranes compared to how they are typically presented in textbooks. Where to look: Sections discussing membrane-protein interactions Paragraphs describing functional consequences of lipid changes Discussion/conclusion sections
