What is the role of enzymes present in glyoxysomes​

Answer» <html><body><p>Glyoxysomes are specialized peroxisomes found in plants (particularly in the fat storage <a href="https://interviewquestions.tuteehub.com/tag/tissues-18036" style="font-weight:bold;" target="_blank" title="Click to know more about TISSUES">TISSUES</a> of germinating seeds) and also in filamentous fungi. Seeds that contain fats and oils include corn, soybean, sunflower, peanut and pumpkin.As in all peroxisomes, in glyoxysomes the fatty <a href="https://interviewquestions.tuteehub.com/tag/acids-366963" style="font-weight:bold;" target="_blank" title="Click to know more about ACIDS">ACIDS</a> are oxidized to acetyl-CoA by peroxisomal β-oxidation enzymes. When the fatty acids are oxidized hydrogen peroxide (H2O2) is produced as oxygen (O2) is consumed.Thus the seeds need oxygen to germinate. Besides peroxisomal functions, glyoxysomes possess additionally the key enzymes of glyoxylate cycle (isocitrate lyase and malate synthase) which accomplish the glyoxylate cycle bypass. Thus, glyoxysomes (as all peroxisomes) contain enzymes that initiate the <a href="https://interviewquestions.tuteehub.com/tag/breakdown-903880" style="font-weight:bold;" target="_blank" title="Click to know more about BREAKDOWN">BREAKDOWN</a> of fatty acids and additionally possess the enzymes to produce intermediate products for the synthesis of sugars by gluconeogenesis. The seedling uses these sugars synthesized from fats until it is mature enough to produce them by <a href="https://interviewquestions.tuteehub.com/tag/photosynthesis-18681" style="font-weight:bold;" target="_blank" title="Click to know more about PHOTOSYNTHESIS">PHOTOSYNTHESIS</a>. Plant peroxisomes also participate in photorespiration and nitrogen metabolism in root nodules.Hope it helpsP.S Mark it as brainliest</p></body></html>
