Question

If photosynthesizing plants are placed into an atmosphere of 14CO2, is every carbon of the glucose that is produced after the placement labeled with the radioactive carbon?a. If the plant was grown for its entire life in a 14CO2 atmosphere, which of the following statements are true?(Select all that apply.b. The ribulose-1,5-bisphosphate that is carboxylated eventually is recycled such that all of its carbons become labeled.c. Only one molecule of 14CO2 is incorporated per molecule of ribulose-1,5-bisphosphate during the dark reactions.d. Because carbohydrate storage in plants is in the form of a disaccharide, no glucose is labeled with 14C.e. The 6 carbons of glucose arise from 6 carbons of 14CO2

Answer 1

b. The ribulose-1,5-bisphosphate that is carboxylated eventually is recycled such that all of its carbons become labeled.

c. Only one molecule of 14CO2 is incorporated per molecule of ribulose-1,5-bisphosphate during the dark reactions
