Explain why this phenomenon is anadvantage to the cell.There are two steps in the TCA cycle that involve the release of free CoA-SH. However, only one of these steps is regulated (i.e. only one of the steps has a large negative delta G). Explain why one of these CoA-SH releasing steps is highly thermodynamically favorable while the other is not.
