In Hatch and Slack pathway, the primary CO2 acceptor is -
1. Oxaloacetic acid
2. Phosphoglyceric acid
3. Phosphoenol pyruvate
4. Rubisco
One scientist cultured Cladophora in a suspension of Azotobacter and illuminated the culture by splitting light through a prism. He observed that bacteria accumulated mainly in the region of:
1. Violet and green light
2. Indigo and green light
3. Orange and yellow light
4. Blue and red light
1. | high energy bonds are formed in mitochondrial proteins |
2. | ADP is pumped out of the matrix into the inter-membrane space |
3. | a proton gradient forms across the inner membrane |
4. | there is a change in the permeability of the inner mitochondrial membrane toward Adenosine Diphosphate (ADP) |
In the leaves of C4 plants, malic acid formation during CO2 fixation occurs in the cells of:
1. mesophyll
2. bundle sheath
3. phloem
4. epidermis
Cyclic -photophosphorylation results in the formation of:

2. ATP and NADPH
3. ATP, NADPH, and O2
4. ATP
In photosynthesis, the light-independent reactions take place at?

2. photosystem I
3. photosystem II
4. Stromal matrix
Emerson’s enhancement effect and red drop have been instrumental in the discovery of?
