Question

imagine the [H+] inside a lysosome was measured to be is 6.9*10^-5. what is the ph and is it normal?

6.9, yes it's normal
4.1, yes it's normal
1.0, no it's not normal
0.9, no it's not normal

when is equilibrium the reaction: GTP <-> GDP + Pi has a Kc= 3.7*10^-5. which of the following is the best estimate of the free energy change associated with this reaction at equilibrium?

Qc=2.3*10^10
Kc=5.3*10^-12
deltaG=0
deltaG=positive

under the study State conditions found in a living cell which of the following is most likely Qc of the reaction shown below is... ATP<-> ADP+Pi

3*10^7
3*10^-7
3*10^2
3*10^-2

Answer 1

imagine the [H+] inside a lysosome was measured to be is 6.9*10^-5. what is the ph and is it normal?

6.9, yes it's normal
4.1, yes it's normal
1.0, no it's not normal
0.9, no it's not normal

pH is –log conc of H+ion pH=-log [H+]= 4.16 and yes it is normal vescicle have acidic pH

when is equilibrium the reaction: GTP <-> GDP + Pi has a Kc= 3.7*10^-5. which of the following is the best estimate of the free energy change associated with this reaction at equilibrium?

At equilibrium free energy del G is zero always

Qc=2.3*10^10
Kc=5.3*10^-12
deltaG=0
deltaG=positive

under the study State conditions found in a living cell which of the following is most likely Qc of the reaction shown below is... ATP<-> ADP+Pi

3*10^7
3*10^-7
3*10^2
3*10^-2

Please describe what is Qc in comments then only I may be able to give response for this (through comments)
