Aresearcher uses a radioactively-labeled carbon dioxide molecule to evaluate photosynthetic rate. in her experiments, the researcher finds adequate consumption of water, generation of oxygen and nadph production, but no change in plant mass. the most likely dysfunctional system in the plant is:

Answer is Calvin cycle.

Explanation:

Calvin cycle is very important to plants because it helps in the conversion of organic products for the usefulness of plants. This is because the carbon dioxide and water are converted to glucose, which is useful to plants.

Calvin cycle can be explained as the production of glucose through the use of chemical energy from NADPH and ATP, produced in light reactions, to convert the atmospheric carbon dioxide to RuBP, which is a five-carbon molecule.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
