Photosynthesis In Higher Plants Question 9
Question: Assertion : Six molecules of $ CO_2 $ and twelve molecules of $ NADP{H^{+}}+{H^{+}} $ and 18 ATP are used to form one hexose molecule. Reason : Light reaction results in formation of $ ATP $ and $ NADPH_2 $ [AIIMS 2002]
Options:
A) If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C) If the assertion is true but the reason is false
D) If both the assertion and reason are false
Show Answer
Answer:
Correct Answer: B
Solution:
Six molecules of $ CO_2 $ enter Calvin cycle to produce one hexose molecule whereas 18 ATP, $ 12NADPH+{H^{+}} $ molecules are used up.
The light reaction of photosynthesis results in $ ATP $ and $ NADPH_2 $ formation.
