d) Urease
VIEW THEORY
Solution
The answer is b) Cytochrome c oxidase.
Explanation for each option:
a) Catalase: This enzyme is involved in breaking down hydrogen peroxide into water and oxygen. It is not part of the electron transport chain.
b) Cytochrome c oxidase: This enzyme is a component of the electron transport chain. It is involved in the final step of electron transfer, where it facilitates the transfer of electrons to oxygen, forming water. This is a key step in aerobic respiration.
c) Coagulase: This enzyme is involved in the coagulation of blood and is not part of the electron transport chain.
d) Urease: This enzyme catalyzes the hydrolysis of urea into carbon dioxide and ammonia. It is not involved in the electron transport chain.
Summary: Cytochrome c oxidase is the enzyme that is part of the electron transport chain in many aerobic bacteria.
