Which order of molecular conversions is correct for the Calvin cycle?
a. $RuBP + G 3 P 鈫� 3 - PGA 鈫� sugar$
b. $R u B i s C O 鈫� C O 2 鈫� RuBP 鈫� G 3 P$
c. $RuBP + CO 2 鈫� [RuBisCO] 3 - PGA 鈫� G 3 P$
d. $CO 2 鈫� 3 - PGA 鈫� RuBP 鈫� G 3 P$

Short Answer

Expert verified

The RuBisCO enzyme is regenerated throughout the Calvin cycle and has a strong affinity for CO2. As a result, option c.

R u B P + C O 2 鈫� [R u B i s C O] 3 - P G A 鈫� G 3 P

is the correct solution.

Step by step solution

step-1: Intoducton

RuBP and CO2 mix in the Calvin cycle in the presence of the enzyme RuBisCO to produce 3-PGA, which is then transformed into G3P in the presence of the energy carriers ATP and NADPH.

step-2: Explanation of the correct answer

In the presence of the enzyme RuBisCO, RuBP and CO2 combine to produce 6 molecules of G3P. Only one molecule of G3P is converted to sugar, while the rest is recycled. As a result, option is the proper response (c).

step-3: Explanation of incorrect answer

Option (a) is incorrect because it occurs in the Calvin cycle in the wrong order. As a result, this is a bad choice.

Option (b) is incorrect because it occurs in the Calvin cycle in the wrong sequence. As a result, this is a bad choice.

Option (d)It does not occur in the Calvin cycle in the correct order of events. As a result, this is a bad choice.
