Which organelle out of these does not participate in photorespiration?...
Chloroplasts
- Chloroplasts are the organelles responsible for photosynthesis in plant cells.
- During photosynthesis, chloroplasts use sunlight, carbon dioxide, and water to produce glucose and oxygen.
- Photorespiration is a process that occurs in plant cells when there is a lack of carbon dioxide, leading to the oxygenation of ribulose-1,5-bisphosphate (RuBP) by the enzyme RuBisCO.
- This process leads to the formation of toxic by-products and can be detrimental to the plant.
- Peroxisomes and mitochondria play a role in photorespiration by helping to break down the toxic by-products and recycle carbon compounds.
- Peroxisomes contain enzymes that convert glycolate, a by-product of photorespiration, into glyoxylate, which can be used in the glyoxylate cycle to produce glucose.
- Mitochondria are involved in the conversion of glyoxylate into glycine, which can then be used in the synthesis of other important molecules.
- Golgi bodies, on the other hand, are responsible for processing and packaging proteins and lipids for secretion or for use within the cell. They do not directly participate in the photorespiration process.
