What are cytochromes?
Q: What are cytochromes?
A: Cytochromes are haemoproteins or proteins containing haem groups.
Q: What do cytochromes do?
A: They make ATP by electron transport.
Q: How are cytochromes found?
A: They are found either as single (monomeric) proteins or as part of bigger enzyme complexes which catalyze redox reactions.
Q: What does the haem group do in cytochromes?
A: The haem group does the redox reactions.
Q: What is the nature of redox reactions?
A: Redox reactions involve the transfer of electrons.
Q: Can you name an example of a single cytochrome protein?
A: Yes, cytochrome c is an example of a single cytochrome protein.
Q: What type of chemical reactions do redox reactions involve?
A: Redox reactions involve all chemical reactions in which atoms have their oxidation state changed.
