Introduction:
When the source of CO2 is removed from photosynthesizing chloroplasts, it has a significant impact on the concentration of certain chemicals involved in the process. Let's examine the correct combination of concentration changes for ATP, Ribulose bishposphate, and Phosphoglyceric acid (PGA).
ATP:
ATP (Adenosine Triphosphate) is a molecule that stores and provides energy for cellular processes. In photosynthesis, ATP is synthesized in the light-dependent reactions and is essential for the light-independent reactions (Calvin cycle). When the source of CO2 is removed, the production of ATP is affected. Therefore, the concentration of ATP will decrease.
Ribulose bishposphate:
Ribulose bishposphate (RuBP) is a 5-carbon sugar molecule that plays a crucial role in the Calvin cycle. It combines with CO2 during the initial step of carbon fixation. Without the source of CO2, the concentration of RuBP will decrease as it is not being utilized.
Phosphoglyceric acid (PGA):
Phosphoglyceric acid (PGA) is a 3-carbon molecule formed during the Calvin cycle. It is the first stable product of carbon fixation. When CO2 is absent, the production of PGA is reduced, leading to a decrease in its concentration.
Combination of concentration changes:
Based on the given options, the correct combination of concentration changes is option D: increases, no change, decreases.
- ATP concentration decreases: When the source of CO2 is removed, the production of ATP is affected, resulting in a decrease in its concentration.
- Ribulose bishposphate (RuBP) concentration remains unchanged: Since the source of CO2 is absent, RuBP is not being utilized, but it is not being consumed either. Therefore, its concentration remains constant.
- Phosphoglyceric acid (PGA) concentration decreases: Without CO2, the production of PGA is reduced, leading to a decrease in its concentration.
Conclusion:
When the source of CO2 is removed from photosynthesizing chloroplasts, the concentrations of ATP, Ribulose bishposphate, and Phosphoglyceric acid (PGA) undergo specific changes. The correct combination of concentration changes is ATP decreases, Ribulose bishposphate remains unchanged, and Phosphoglyceric acid (PGA) decreases.
