Question

ATP synthase consists of

• A. $C{F}_1$ and $C{F}_2$
• B. $C{F}_2$ and $F_0$
• C. $C{F}_0$ and $C{F}_1$
• D. $CF$ and $C{F}_1$

Answer 1

The correct option is C $C{F}_0$ and $C{F}_1$

ATP synthase is an enzyme located in the chloroplast and helps in the synthesis of ATP. The chloroplast ATP synthase has two parts: $C{F}_0$ located in the thylakoid membrane and $C{F}_1$ that protrudes on the outer surface of the thylakoid membrane facing the stroma. The $C{F}_0$ forms a transmembrane channel for the movement of protons due to which energy is released and that causes conformational changes in the $C{F}_1$ of the enzyme. Utilising this energy, ATP is synthesised from ADP by the enzyme ATP synthase.
