Question:
C\(_3\) plants utilize 18 molecules of ATP to synthesize one molecule of glucose from CO\(_2\). How many molecules of ATP equivalents are used by C\(_4\) plants to synthesize one molecule of glucose from CO\(_2\)?
C\(_3\) plants utilize 18 molecules of ATP to synthesize one molecule of glucose from CO\(_2\). How many molecules of ATP equivalents are used by C\(_4\) plants to synthesize one molecule of glucose from CO\(_2\)?
Show Hint
C\(_4\) plants utilize more ATP due to their additional carbon fixation mechanism, which requires more energy compared to C\(_3\) plants.

Correct Answer: 30
Solution and Explanation
Step 1: Understanding the ATP requirements in C\(_3\) and C\(_4\) plants.
C\(_3\) plants require 18 molecules of ATP to synthesize one molecule of glucose. C\(_4\) plants, due to their additional mechanism for carbon fixation (C\(_4\) cycle), require more ATP for the same process. Typically, C\(_4\) plants require 30 ATP equivalents to synthesize one glucose molecule.
Step 2: Conclusion.
The correct answer is (C) 30, as C\(_4\) plants require 30 ATP equivalents to synthesize one glucose molecule.

The vector, shown in the figure, has promoter and RBS sequences in the 300 bp region between the restriction sites for enzymes X and Y. There are no other sites for X and Y in the vector. The promoter is directed towards the Y site. The insert containing only an ORF provides 3 fragments after digestion with both enzymes X and Y. The ORF is cloned in the correct orientation in the vector using the single restriction enzyme Y. The size of the largest fragment of the recombinant plasmid expressing the ORF upon digestion with enzyme X is ........... bp. (answer in integer)
