Answer 1

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
