Question

The use of [ 14C] radioactive carbon by M. Calvin in algal photosynthesis studies provided

• A. That CO2 will combine with H2O to produce sugar.
• B. That ATP and NADPH were used in the biosynthetic phase.
• C. That first CO2 fixation product was 3-carbon organic acid.
• D. All of the above

Answer 1

The correct option is D All of the above

The use of radioactive carbon by M.Calvin in algal photosynthesis studies :

Correct option is (D).

In C3 pathway carbon dioxide is converted into sugar and further ATP and NADPH were used . The first stable compound in the C3 pathway is 3-Carbon organic compound that is 3 phosphoglyceric acid (3PGA).

Hence, The correct option is D.
