Question

The The enzyme ATP synthase consists of two parts - F1 and Fo. Identify the TRUE statements from those given below: (a) F1 and Fo are mobile electron carriers. (b) Fo is integral and F1 is peripheral membrane protein complexes (c) Fo obstructs the movement of proton through it (d) F1 is the site of ATP synthesis

• A. (a), (c) and (d) are true
• B. (b) and (d) are true
• C. (d) alone is true
• D. All are true

Answer 1

Answer:

B. (b) and (d) are true

The enzyme ATP synthase is made up of two parts, F1 and Fo, with Fo being integral and F1 being a peripheral membrane protein complex: F0 A transmembrane channel that allows protons to pass through the mitochondrial membrane. It's embedded in the inner membrane and forms a proton turbine. F1 A peripheral membrane protein complex that protrudes into the mitochondrial matrix. It contains the catalytic sites for ATP synthesis.
