If true,which of the following is the best evidence that the cyanelles are providing nutrition (in other words,calories)to the surrounding cercozoan? A)if the cyanelle performs aerobic photosynthesis B)if the vesicle membrane that surrounds each cyanelle possesses glucose-transport proteins C)if the cyanelle performs aerobic respiration D)if radiolabeled ¹⁴CO₂ enters the cyanelle and if,subsequently,radiolabeled glucose is present in cercozoan cytosol

Question

Quizplus · Accepted Answer

Radiolabeled ¹⁴CO₂ is a form of radiolabeled sucrose, which is a type of sugar. If this radiolabeled sucrose enters the cyanelle and radiolabeled glucose is found in the cercozoan cytosol, it is evidence that the cyanelles are providing nutrition (in the form of sugar) to the surrounding cercozoan. The presence of glucose-transport proteins in the vesicle membrane (choice B) is not specific to providing nutrition from cyanelles, as these proteins could be involved in transporting glucose from other sources. Choices A and C are not relevant to determining if nutrition is being provided by the cyanelles.
