1. The given structure is of Oxysome/ F1 Particle.
2. A: Head (F1 )
B: Pedicel
C: Foot (Base / F0 )
3. Structure of Oxysome:
a. Inner membrane of mitochondria bears numerous particles called as Oxysomes (F1 – F0 / Fernandez – Moran Elementary particles / Mitochondrial particles).
b. Each particle consists of head, stalk (Pedicel) and base.
c. Head (F1 ) / lollipop head faces towards matrix and foot (F0) is embedded in inner membrane.
d. Head acts as an enzyme ATP synthase and foot (base) as proton channel. Oxysomes are involved in proton pumping and ATP synthesis
