Typical visible<br />
absorption spectra of<br />
cytochromes. (a)<br />
Cytochrome c, reduced<br />
spectrum; (b)<br />
cytochrome c, oxidized<br />
spectrum; (c) the<br />
difference spectrum: (a)<br />
minus (b); (d) beef heart<br />
mitochondrial particles:<br />
room temperature<br />
difference (reduced<br />
minus oxidized)<br />
spectrum; (e) beef heart<br />
submitochondrial<br />
particles: same as (d)<br />
but at 77 K. α- <strong>and</strong> β-<br />
b<strong>and</strong>s are labeled, <strong>and</strong><br />
in (d) <strong>and</strong> (e) the b<strong>and</strong>s<br />
for cytochromes a, b <strong>and</strong><br />
c are indicated.<br />
