Glyoxysomes are specialized organelles found in which context?

Glyoxysomes are specialized peroxisomes that enable the glyoxylate cycle, allowing fatty acids to be converted into carbohydrates rather than being fully oxidized to CO2. This pathway is crucial during seed germination, when a plant seed uses stored fats from oil bodies to fuel growth until it can become autotrophic via photosynthesis. The ability to turn acetyl-CoA from fatty acids into succinate and then glucose-like sugars provides the seedling with an immediate carbon source to build essential biomolecules and energy. Because this fatty-acid-to-sugar conversion is a feature of plant seeds, glyoxysomes are found there. In animals, including liver and muscle tissues, energy metabolism relies on other pathways, and there isn’t a glyoxylate cycle functioning in those cells. Bacteria generally do not contain glyoxysomes, since this organelle is a eukaryotic, plant-associated feature.
