Question

Removal of the source of carbon dioxide from photosynthesizing chloroplasts
results in rapid changes in the concentration of certain chemicals. Which one
of the following represents the correct combination of concentration changes?
​

Answer 1

Answer:

The assimilation of carbon into organic compounds is the result of a complex series of enzymatically regulated chemical reactions—the dark reactions. This term is something of a misnomer, for these reactions can take place in either light or darkness. Furthermore, some of the enzymes involved in the so-called dark reactions become inactive in prolonged darkness; however, they are activated when the leaves that contain them are exposed to light.

Explanation:

Pathway of carbon dioxide fixation and reduction in photosynthesis, the reductive pentose phosphate cycle. The diagram represents one complete turn of the cycle, with the net production of one molecule of Gal3P. The nine molecules of ATP and six molecules of NADPH come from the light reactions.

Answer 2

Answer:

Pathway of carbon dioxide fixation and reduction in photosynthesis, the reductive pentose phosphate cycle.
