Real questions that test this

प्रकाश-संश्लेषणामध्ये प्रकाशावर आधारित प्रक्रियेचे महत्त्वाचे कार्य कोणते आहे ? What is the principal function of the light-dependent reactions of photosynthesis ?

a)NADH₂ व ATP चे रूपांतर करणे / To transfer the NADH₂ and ATP
b)NADPH व ATP चा उपयोग करणे / To utilize the NADPH and ATP
c)NADPH व ATP ची निर्मिती करणे / To generate the NADPH and ATP✓ Correct
d)वरील सर्व / All of the above

The light-dependent reactions of photosynthesis capture solar energy to generate energy-rich molecules NADPH and ATP.

खालीलपैकी कोणती प्रक्रिया श्वसन प्रक्रियेत अंतर्भूत नाही ? Which among the following is not involved in Respiratory Process ?

1)(1) केल्व्हिन सायकल / Calvin cycle✓ Correct
2)(2) सायट्रीक ॲसिड सायकल / Citric acid cycle
3)(3) ग्लायकोलीसिस / Glycolysis
4)(4) इलेक्ट्रॉन ट्रान्सपोर्ट चेन / Electron transport chain

The Calvin cycle is part of photosynthesis (dark reaction), not respiration. Respiration involves glycolysis, Kreb's (citric acid) cycle, and electron transport chain.

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).
