Q. No.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:
| 1. | green and orange | 2. | red and blue |
| 3. | infrared and yellow | 4. | red and green |
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:
| 1. | Manganese and Magnesium | 2. | Manganese and Calcium |
| 3. | Calcium and Iron | 4. | Magnesium and Iron |
In oxygenic photosynthesis, the release of oxygen is a byproduct of:
1. chemiosmosis
2. reducing by FNR
3. splitting the water molecules
4. cyclic photophosphorylation
The greatest problem with photorespiration is faced by:
| 1. | C4 plants | 2. | C3 plants |
| 3. | CAM plants | 4. | purple sulfur bacteria |
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 |
The higher the energy in photons,
| 1. | the longer their wavelengths |
| 2. | the shorter their wavelengths |
| 3. | the lesser will be the rate of photosynthesis |
| 4. | the larger will be the photorespiratory loss |
