Document Summary
In this set of lectures, we"ll talk about cell energetics and. We"ll show that basic thermodynamic considerations apply equally well to life as all. We"ll talk about reactions and how free energy controls their direction, and the. We"ll talk about activation energies controlling reaction kinetics. 1089 [00:00:26. 22] we"ll talk about how the cell does energetically unfavorable reactions by coupling. 1090 them to energetically favorable ones, which are always more favorable in magnitude then the. We"ll give an example of how enzymes reduce activation. 1092 energies and then we"ll talk a little bit about protein folding, which has some conceptual. But it"s hard for us to fully grasp how they. 1095 [00:01:05. 62] the simplest view of energetics of cells is that we consume food. 1096 two things; we break the food down, we get useful forms of energy, and we get building blocks. 1097 of molecules that we want to make. Then we can combine these building blocks using some of.
