So what that means is we're not contracting those skeleton muscle cells and so they're not using ATCP molecules to actually generate those contractions of the actin mice and filaments. And under such conditions we're going to build up our ATP concentration. We're going to have a high energy charge value. Remember, the energy charge basically tells us the relative concentration of ATP. And if the energy charge is high, we're going to have a high concentration of ATP in our cell. Now, if we have plenty of ATP molecules, we're also going to have plenty of intermediate molecules that help us produce those ATPs.
