MCAT Biological and Biochemical Foundations of Living Systems Flashcards: 2a Membrane Transport Osmoregulation

Study 2a Membrane Transport Osmoregulation in MCAT Biological and Biochemical Foundations of Living Systems with focused flashcards that help you recognize the idea, recall the key rule, and apply it in practice-style prompts.

QUESTION

What is the term for red blood cell rupture after excessive swelling in a hypotonic solution?

Tap card or press Space to flip

ANSWER

Hemolysis. Excessive water influx in hypotonic conditions causes the red blood cell to swell beyond its membrane's capacity, leading to rupture.

A freshwater fish was exposed to water containing an inhibitor of gill Na+$/Cl^+$/Cl^-$ uptake transporters. Plasma osmolality and urine flow were measured after 4 hours. Table: Condition vs plasma osmolality (mOsm/kg) and urine flow (mL/kg/hr)
  • Control: 300; 8
    • uptake inhibitor: 270; 10
Principle tested: active ion uptake in freshwater supports osmotic balance against passive ion loss and water gain. Which outcome is most consistent with the osmoregulatory process described?
