Question

The chemiosmotic model requires that mitochondrial ATP synthesis and electron flow through the respiratory chain be obligately coupled. O requires an intact outer mitochondrial membrane. o is supported by the observation that isolated mitochondria that are actively respiring cause is supported by the observation that, when isolated mitochondria have an artificial spontaneously flow through the respiratory chain. O electrochemical gradient (higher pH in the matrix) imposed on them, electrons The Bsubunits of ATP synthase O have three distinct isozymes. O are each associated with a o subunit. O have three distinct conformations. will act as an ATPase if protons flow through the Fo domain into the mitochondrion.

Explanation / Answer

1)-option d is correct because in it action of ATP synthase coupled with the proton gradient and an artificial established pH gradient in inner membrane should be able to drive ATP synthesis.

2)-option c is correct because beta subunit undergo conformational change leading to formation of ATP from ADP.
