झाडांच्या श्वासोच्छवासाच्या क्रेब्च्या चक्रादरम्यान खालीलपैकी कोणत्या प्रक्रियेद्वारे फ्यूमॅरीक अॅसिडचे रूपांतर मॅलीक अॅसिड मध्ये होते ? During Krebs cycle in respiration, fumaric acid gets converted into malic acid by
During the Krebs cycle (citric acid cycle) in cellular respiration, fumaric acid is converted into malic acid through the addition of a water molecule, which is known as a hydration reaction. Note: MPSC's official key gives option 2 (dehydrogenation), but the fumarate-to-malate step is catalysed by fumarase and adds a water molecule, which is hydration; this site keeps the scientifically correct answer.
सुक्रोजचे एरोबिक ऑक्सिडीकरण होऊन अधिकतम किती ATP तयार होतात ? The maximum yield of ATP from the complete oxidation of sucrose via aerobic respiration is
Sucrose is a disaccharide made of glucose and fructose. Complete aerobic oxidation of one sucrose molecule yields a maximum of about 40 ATP molecules through glycolysis, Krebs cycle, and oxidative phosphorylation.
