NADPH is generated through
photosystem-I
photosystem-II
anaerobic respiration
glycolysis
In photosystem-I the first electron acceptor is
cytochrome
plastocyanin
an iron-sulphur protein
ferredoxin
Dark reactions of photosynthesis occur in
granal thylakoid membranes
stromal lamella membranes
stroma outside photosynthetic lamellae
periplastidial space
Greatest producers of organic matter are
crop plants
forests
plants of the land area
phytoplankton of oceans
The C4-plants are photosynthetically more efficient than C3-plants because
the CO2 compensation point is more
CO2 generated during photorespiration is trapped and recycled through PEP carboxylase
the CO2 efflux is not prevented
they have more chloroplasts
Which pigment system is inactivated in red drop?
PS-I and PS-II
PS-I
PS-II
None of these
Maximum solar energy is trapped by
planting trees
cultivating crops
growing algae in tanks
growing grasses
A photosynthesizing plant is releasing 18O more than the normal. The plant must have been supplied with
O3
H20 with 18O
CO2 with 18O
C6H12O6 with 18O
Which of the following absorb light energy for photosynthesis?
Chlorophyll
Water molecule
O2
RuBP
Cytochrome is
metallo flavo protein
Fe-containing porphyrin pigment
glycoprotein
lipid
