B Cytochromes were initially described in 1884 by Macmunn as respiratory pigments. They are found in the cristae of mitochondria, cytochrome are a group of proteins involved in redox reaction. They contain $\mathrm{Fe}$ containing the heme group at its core. They are involved in the electron transport chain present in the Inner mitochondrial membrane or cristae. The electron transport chain contains two cytochrome complexes consisting of cytochrome A, B, C and D.

The size of chlorophyll molecule is
1 head $15 \times 15 \AA^{\circ}$, tail $25 \AA^{\circ}$
2 head $20 \times 20 \stackrel{\circ}{\mathrm{A}}$, tail $25 \AA^{\circ}$
3 head $15 \times 15 \stackrel{\circ}{\AA}$, tail $20 \stackrel{\circ}{\AA}$
4 head $10 \times 12 \stackrel{\circ}{\mathrm{A}}$, tail $25 \AA^{\circ}$
Explanation:
C Term 'chlorophyll' is used by Caventoy consists of a flat or squire head $15 \times 15 \AA$ hydrophilic in nature made up of porphyrine ring of tetrapyrol, in which Mg lies in the center and a long tail about $20 \AA$ in length, hydrophilic in nature or lipophilic made up of phytol $\left(\mathrm{C}_{20} \mathrm{H}_{39} \mathrm{OH}\right)$. Chlorophyll insoluble in water, green in colour absorb blue and red light of wavelength and reflected or transmit green light.
