FoundationWhich pigment serves as the reaction-center pigment in oxygenic plant photosystems?
Need a small nudge?

Accessory pigments broaden light capture, but one chlorophyll type occupies the reaction centers.

UnderstandingWhich statement best describes the immediate carbon product exported from the Calvin cycle?
Need a small nudge?

The Calvin cycle exports a three-carbon building block.

ApplicationA green plant is moved into continuous darkness but still has stored carbohydrate and oxygen. Which process can continue for a time?
Need a small nudge?

Plants respire as living organisms even when light is absent.

InterpretationWhen Rubisco reacts with oxygen instead of carbon dioxide, what pathway begins?
Need a small nudge?

Rubisco is both a carboxylase and an oxygenase.

ConnectionWhich summary correctly connects photosynthesis and respiration in a plant cell?
Need a small nudge?

One pathway builds energy-rich carbon compounds; the other can break them down for ATP.
