The absorption spectrum in the given diagram will be of:
  

1.	Chlorophyll a	2.	Chlorophyll b
3.	Carotenoids	4.	Retinol

The reactions of the Calvin Cycle occur in:
1. stroma of the chloroplast
2. thylakoid membrane
3. lumen of the thylakoids
4. space between outer and inner membrane of the chloroplast

The wavelengths of light most useful in photosynthesis are:

The correct chronological sequence of protein complexes in the thylakoid membrane involved in light reactions is:
1. Photosystem II (PS II), Cytochrome b6f complex, Photosystem I (PS I), and ATP synthase.
2. Photosystem I (PS I), Cytochrome b6f complex, Photosystem II (PS II), and ATP synthase.
3. Photosystem II (PS II), Photosystem I (PS I), Cytochrome b6f complex, and ATP synthase.
4. Photosystem I (PS I), Photosystem II (PS II), Cytochrome b6f complex, and ATP synthase.

The enzymes for synthesis of organic molecules, in autotrophic bacteria, are located:
1. on chloroplast membranes
2. in the cytosol
3. in the nucleoid region
4. along the inner surface of the plasma membrane

Oxygen, during oxygenic photosynthesis, is produced during:
1. cyclic photophosphorylation
2. the light-dependent reactions involving photosystems I and II
3. Calvin cycle
4. the Krebs cycle

The ions comprising the Oxygen Evolving Complex associated with PS II are:

In oxygenic photosynthesis, the release of oxygen is a byproduct of:
1. chemiosmosis
2. reducing ${\mathrm{NADP}}^{+}$ by FNR
3. splitting the water molecules
4. cyclic photophosphorylation

The greatest problem with photorespiration is faced by:

The net reaction of all light-dependent reactions in oxygenic photosynthesis is:
1. 2H₂O + 2NAD⁺ + 3ADP + 3Pi \(\rightarrow\) O₂ + 2NADH + 3ATP
2.  2H₂O + 3NAD⁺ + 2ADP + 3Pi \(\rightarrow\) O₂ + 3NADH + 2ATP
3.  2H₂O + 2NADP⁺ + 3ADP + 3Pi \(\rightarrow\) O₂ + 2NADH + 3ATP
4.  2H₂O + 3NADP⁺ + 2ADP + 3Pi \(\rightarrow\) O₂ + 3NADH + 3ATP
