Question
1.Why does photosynthesis require two photosystems to produce NADPH?
It provides for a greater variety of wavelengths to be absorbed
It allows for ATP to be converted to NAD+
It's an evolutionary artifact
It allows photosynthesis to work twice as fast
Because the energy of one photon is less than the energy of converting NADP to NADPH
It allows photosynthesis to make twice as much ATP
It allows NADPH to be made that has more energy than the ordinary NADPH molecules
2.
DAPI is a cellular stain that....
Question 2 options:
Turns proteins blue
Turns nucleic acids green
Makes nucleic acids fluoresce in blue
Makes chloroplasts fluorescent
Binds to cell walls and turns them green

Explanation / Answer
1. IIt allows for ATP to be converted to NAD+
2. Makes nucleic acids fluoresce in blue
3. NADPH- Nicotinamide adenine dinucleotide phosphate
4. 2 x 2 = 4 different combinations.
