The overall energy change of a chemical reaction (AG) can be expressed as: AG = AH – TAS (AH represents heat release/absorption. AS represents entropy) Many cell processes lead to a large decrease in entropy (form more ordered, higher energy states), which is energetically unfavorable. Explain how absorbing or releasing heat can help balance this out and make these processes more favorable. (Bonus: Some metabolisms only "work" at high temperatures. Explain how high temperatures would make a reaction more favorable, using the same equation) %3D
