400
What are the electron carriers in cellular respiration and in photosynthesis?
NADPH and FADPH; NADH and FADH2
500
Why does the photon cause the electron to jump to chlorophyll A? Explain.
The electron is quantized and heated which makes it excited and jump.
500
How are C4 and CAM plants evolutionary adaptations?
They allow plants to overcome the limitations of rubisco and their need to reserve water and heat.
