I was reading my Biochem book and it states that a closed system exchanges energy, but not matter. I though you said the opposite in class. Also, for today's lecture, I was confused on where the lecture is taking us. Are we studying the probability of empty sites that will later translate to sites on enzymes or some other typing of bonding in the cell?
Closed systems are those that can exchange energy, but not mass. Isolated systems are those that exchange neither.
The example worked in class was just a simple case to illustrate the properties of Boltzmann probabilities. We will not connect this specific example to any biomolecular process; however, the final, general equations that we arrived at, namely the connection between state probabilities and free energies, will be used quite extensively.
