Questions

  1. 1.

    How do living organisms obey the second law of thermodynamics while maintaining a highly ordered, low-entropy internal state?

    • A) They convert absorbed chemical energy into cellular work with complete efficiency, preventing any energy dispersal.
    • B) They function as open systems that take in free energy and release heat and waste, increasing the total entropy of the universe.
    • C) They exist as thermally isolated closed systems that spontaneously lower internal entropy without interacting with their surroundings.
    • D) They utilize enzyme catalysis to temporarily suspend thermodynamic laws during endergonic biosynthetic pathways.
