WebThe Citric Acid Cycle 5 Step-wise reactions of the TCA cycle 1. Aldol condensation of oxaloacetate with acetylCoA followed by hydrolysis of CoASH to give citrate. Enzyme: citrate synthase. This is the first irreversible step 2. Dehydration followed by hydration leads to interchange of -H and –OH and isomerization of citrate to isocitrate.

Several catabolic pathways converge on the citric acid cycle. Most of these reactions add intermediates to the citric acid cycle, and are therefore known as anaplerotic reactions, from the Greek meaning to "fill up". These increase the amount of acetyl CoA that the cycle is able to carry, increasing the mitochondrion's capability to carry out respiration if this is otherwise a limiting factor. Processes that remove intermediates from the cycle are termed "cataplerotic" reactions. WebMar 10, 2024 · The reactions of the citric acid cycle occur in the mitochondria in eukaryotic cells.
