5 Written Questions

1. Absorb solar energy and convert it to chemical energy stored in ATP and NADPH
2. oxygen, ATP, NADPH
3. Energy from light, water, ADP + P, NADP+
4. Two chemical reactions consume energy from six molecules of ATP and oxidize six molecules of NADPH. Six molecules of 3-PGA are reduced, producing six molecules of G3P
5. Sugar, NADP+, ADP + P

4. 1st step of the Calvin cycle
5. Stomata

1. a Tiny pores where carbon enters and oxygen exits
2. b Carbon fixation
3. c A series of chemical reactions uses energy from ATP to rearrage the atoms in the five G3P molecules (15 carbons total), forming three RuBP molecules (15 carbons). These can start another turn of the cycle
4. d Consists of a number of light-harvesting complexes surrounding a reaction center complex
5. e A light-absorbing pigment in the chloroplasts that plays a central role in the chloroplasts
