Fig. 21-10 cytosol 15 Acetyl-CoA comes from citrate, which can come Acetyl-CoA out of the TCA cycle (under what conditions?) out But there’s a “location” problem, And a problem of reducing power… 11.4.06 One Transporter is Not Enough!
cytosol Fig. 21-10 16 And malic And enzyme can also be part of the solution the Under what Under conditions would the cell want to have abundant acetyl-CoA in the cytosol? the
