sure of the sugar G3P? a. Light energy directly provides energy to RuBP and CO2, which produce G3P in the Calvin cycle. b. Light energy directly provides energy to ATP synthase, which produces ATP during the light reactions. c. Light energy energizes electrons to make ATP and NADPH, which provide energy to produce G3P in the Calvin cycle.

Give typing answer with explanation and conclusion

Determine the order of the steps in photosynthesis and how they are interconnected in the light dependant reaction stages of photosynthesis

When is oxygen produced during photosynthesis? a. light reation alone b. light reation and calvin cycle c.neither the light reaction and calvin cycle d. the calvin cycle alone

Explain what might happen if the third step of the Calvin cycle did not occur. Why?

Which is NOT an evolutionary adaptation of plants to minimize the costs of photorespiration while also conserving water on hot days?   a. Use more ATP to incorporate CO2 into organic compounds, which increases CO2 concentration in the cell.   b. Confine the Calvin cycle to specific cells in order to prevent inefficient rubisco binding and net energy loss.   c. Binding O2 to rubisco instead of CO2.   d. Uptake CO2 only at night and use ATP to fix it into organic acid for later use during the light reactions, which prevents water loss during the day.

What are the roles of ATP and NADPH in photosynthesis?     a. ATP and NADPH are forms of chemical energy produced from the light dependent reactions to be used in the light independent reactions that produce sugars. b. ATP and NADPH are forms of chemical energy produced from the light independent reactions, to be used in the light dependent reactions that produce sugars. c. ATP and NADPH are forms of chemical energy produced from the light dependent reactions to be used in the light independent reactions that produce proteins. d. ATP and NADPH are forms of chemical energy produced from the light dependent reactions to be used in the light independent reactions that use sugars as reactants.

How is the difference made up in the Calvin cycle when more ATP is used than NADPH? A. The Calvin cycle occurs half as often as the light-dependent reaction B. The cyclic pathway creates more ATP C. Additional ATP is created from glucose D. Excess NADPH is reused in the light reaction

Explain all the stages of the Calvin cycle
