Gastric juice (ph 1.5) is produced by pumping hcl from blood plasma (ph 7.4) into the stomach. calculate the amount of free energy required to concentrate the h+ in 1 l of gastric juice at 37 degrees c. under cellular conditions, how many moles of atp must by hydrolyzed to provide this amount of free energy? the free energy change for atp hydrolysis under cellular conditions is about -58 kj/mol. ignore the effects of the transmembrane electrical potential.

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
