Transport through Membranes I Flashcards
1
Q
Free energy equation for a charged molecule
A
Delta G = 2.303 RT Log (C2/C1) + The electrical charge of the transported speciesFaraday’s constant Membrane potential
2
Q
What is significant about positive free energy?
A
it means the transport is not favored to happen spontaneously so it will require energy to be completed meaning it will use an active transport mechanism
3
Q
What is the characteristic of a P type ATPase?
A
phosphate from the ATP actually forms a covalent bond with the enzyme
4
Q
What is the equation for calculating the free energy for uncharged molecules?
A
Free energy= 2.303gas constantTemp in kelvins* log (concentration on side 2/Concentration on side 1)
Delta G= 2.303 RT log (C2/C1)
