Real questions that test this

सुक्रोजचे एरोबिक ऑक्सिडीकरण होऊन अधिकतम किती ATP तयार होतात ? The maximum yield of ATP from the complete oxidation of sucrose via aerobic respiration is

1)37

2)44

3)60✓ Correct

4)50

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.

ऑक्सश्वसनानाच्या शेवटी काय तयार होते ? The end product of aerobic respiration is :

1)CO2 + CO

2)CO2 + NO

3)CO2 + O2

4)CO2 + H2O✓ Correct

During aerobic respiration, glucose is completely broken down in the presence of oxygen to produce carbon dioxide, water, and energy (ATP).

खालीलपैकी कोणती पायरी श्वासोच्छवास प्रक्रियेतील नाही? Which one of the following is not an intermediate step in Respiration?

1)ग्लुकोज → ग्लुकोज-6-फॉस्फेट / Glucose → glucose-6-phosphate

2)फ्रुक्टोस 1-6 डायफॉस्फेट → फ्रुक्टोस-6-फॉस्फेट / Fructose 1-6 diphosphate → Fructose-6-phosphate✓ Correct

3)फ्रुक्टोस-6-फॉस्फेट → फ्रुक्टोस 1,6-फॉस्फेट / Fructose-6-phosphate → Fructose 1,6-phosphate

4)1-3 डाय पिजीए → 3पिजीए / 1-3 di PGA → 3PGA

Respiration involves processes like ventilation, external respiration, transport of gases, and internal respiration. Intermediate steps exclude non-respiratory metabolic pathways.
