The size of chlorophyll molecule is
head 15 x 15Å, tail 25Å
head 20 x 20Å, tail 25Å
head 15 x 15Å, tail 20Å
head 10 x 12Å, tail 25Å
In C3-plants, the first stable product of photosynthesis during the dark reaction is
malic acid
oxaloacetic acid
3-phosphoglyceric acid
phosphoglyceraldehyde
In sugarcane plant14Co2 is fixed in malic acid, in which the enzyme that fixes CO2 is
fructose phosphatase
ribulose biphosphate carboxylase
phosphoenol pyruvic acid carboxylase
ribulose phosphate kinase
Dark reactions of photosynthesis occur in
granal thylakoid membranes
stromal lamella membranes
stroma outside photosynthetic lamellae
periplastidial space
The first step of photosynthesis is
excitation of electron of chlorophyll by a photon of light
formation of ATP
attachment of CO2 to 5 carbon sugar
ionisation of water
Photosystem-II occurs in
stroma
cytochrome
grana
mitochondrial surface
