During the electron transport in mitochondria which of the following changes are observed. (1) The pH of the matrix increases. (2) ATP synthase synthesizes one molecule of ATP when a pair of the proton is transferred back to the matrix. (3) N A D + is oxidised.
Options
- Aonly 1
- B1 and 2
- C2 and 3
- D1 , 2 and 3
Correct answer
D. 1 , 2 and 3
Step-by-step solution
pH of matrix increases as protons are transferred to perimitochondrial space. N A D + is oxidized as it gives its hydrogen to complex I of ETS. One molecule of ATP is synthesised by ATPase when a pair of one pair proton moves from its higher concentration in PMS to matrix.
