Question

Å - Question 4 Researchers set up an experiment to find the free-energy change (AG) of transporting an unchanged solute molecule. The that AG of transporting this specie to the cell at 25°C is -17 Imol. Interpret this finding This free-energy change comes from the calculation of the membrane potential This transport process requires an input of free energy Th e se passive transport This type of transport requires an ATP-driven pump Question 5 The net result of the actie transport of ABC transporters and P type ATPases is the same; the transporters are bound with ATP in any conformations that allow the drugs to be transported before affecting cells coupled by the ATP hydrolysis reaction to conformational changes converted from one conformation that binds a substrate from one side of the membrane to another conformation that releases the subs to the other side re t to dues due to the other membrane s ing domain to release the nut out of the cell without coupling with ATP Question 6 What is the CORRECT function of the SERCA domin? tab | тү

Answer 1

Ans-4- since the solute is uncharged free energy doesn't depends upon membrane potential. Value if delta G is negative means reaction is exergonic and occurs spontaneously as in case of passive diffusion. ATP is not required for exergonic reaction.

So option C (this species uses passive transport is correct)

Ans-5- ABC transporter and P type ATPase both requires ATP hydrolysis and are example of active transporter. ABC transporter can transport drug out of the cells but the transport is mostly unidirectional while the transport of P type is mostly symport. Hydrolysis of ATP allow the change on conformation that helps to deliver the target molecule.

So option B is correct
