Homework Answers
Answer: This statement states that the exergonic reactions are which generates the energy while those reaction which requires energy to initiate a reaction is known as endergonic reactions. So, here the second law of thermodynamics is applied to understand this statement. To reduce the loss of the energy both the endergonic and exergonic reactions are combined.

Your classmate is excited to tell you about something they just learned. There’s a toxin named ouabain that was used by East Africans to make poison arrows. “And guess what-ouabain kills people by blocking the sodium/potassium pump that we learned about in BILD 1!” But your classmate is confused about something. “The sodium/potassium pump moves sodium and potassium ions against the concentration gradients, in the opposite direction of how the ions would normally go. But in class we said that...
