g Plants are able to convert two moles of acetyl‑CoA into one mole of oxaloacetate with only two additional enzymes not found in
animals. This process is called the glyoxylate cycle, and it occurs in organelles called glyoxysomes. Classify the enzymes based on whether they are found only in plants or are found in both plants and animals. Enzymes found in plants only Enzymes found in plants and animals
The glyoxylate cycle occurs in the cell organelle glyoxysomes. This cycle is related to the Citric acid cycle but this cycle overlaps all of the non-decarboxylation reactions of the Citric acid cycle.
The glyoxylate cycle operates in plant cells and bacteria but it is absent in animals because they lack two enzymes which are important for the cycle. These enzymes are isocitrate lyase and malate synthase. Isocitrate lyase converts isocitrate into succinate and glyoxylate which combines with another acetyl-CoA to form malate. The malate later oxidised to oxaloacetate.
