A.T.P.synthase transports protons "(H')" :-

According to chemiosmotic hypothesis, ATP synthetase form ADP when protons (H^+) ,

The energy from electron transport is utilized in transporting proton (H^+) from

Number of H+ that must be transported through ATP synthase or coupling factor ( CF_(0) -CF1) to form one ATP is

Which is a stronger base towards a proton overset (Ө) P H _2 or overset (Ө) NH_2 ?

The current through a wire connected to a condenser varies with time as i=(2t+1)A the charge transport to the condenser from t=0 to t=5s is

ADP to ATP reaction occurs when two protons (H^(+)) are passed from

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) NAD^(+) is oxidised.

Following steps in random order are given below for photophsophorylation through chemiosmosis I ATP synthase produces ATP due to flow of H^(+) form thylakoid lumen to stroma II NADP reductase located on stroma side of membrane obtains e^(-) froms PSI and protons from stroma to form NADPH_(2) IIICyotchrome system (B&F) transport electrons and pumps H^(+) form stroma to thylakoid space IV PSII oxidises water V Reaction centre of PSII gets photoecited having released electrons

An electron (mass m_(e ) )falls through a distance d in a uniform electric field of magnitude E. , The direction of the field is reversed keeping its magnitudes unchanged, and a proton(mass m_(p) ) falls through the same distance. If the times taken by the electrons and the protons to fall the distance d is t_("electron") and t_("proton") respectively, then the ratio t_("electron")//t_("proton") .

Assertion: The reduced ubiquinone (ubiquinol) is oxidised with the transfer of electron to cytochrome c. Reason: During electron transport, proton accumulates within inner membrane of mitochondria.
