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.

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.
