Frage 1
Frage
Tenet 1- The membrane should be permeable to protons
Frage 2
Frage
Tenet 2 - An electron transport chain powers the pumping of protons across a cell membrane
Frage 3
Frage
Tenet 3- Energy transducing membranes must have special systems allowing ions and metabolites to pass (to maintain osmotic pressure in the case of a high membrane potential)
Frage 4
Frage
Tenet 4- The ATP synthase should NOT also act as an ATP translocator
Frage 5
Frage
Why does disrupting the inner mitochondrial membrane increase alkylisation of the medium?
Antworten
-
The inner membrane becomes more permeable and protons enter the mitochondria down the concentration gradient
-
The inner membrane becomes more permeable and protons leave the mitochondria down the concentration gradient
Frage 6
Frage
Why does O2 injection acidify the membrane and prove chemiosmotic theory?
Antworten
-
The O2 allows protons to be pumped out of the inner membrane into the solution, acidifying it
-
The O2 allows protons to be pumped out of the solution into the mitochondria acidifying it
-
The medium then alkylises as they flow back in
Frage 7
Frage
The number of protons pumped is substrate dependent
Frage 8
Frage
What is this the symbol for in the protonmotive force equation?
Frage 9
Frage
Put the Protonmotive force equation in order; Change in PMF = _ - (_ x _)
A = Farraday constant
B = Change in pH
C= Change in electrical potential
Frage 10
Frage
Short circuiting the protonmotive force generation system causes the energy to be released as heat
Frage 11
Frage
The number of protons pumped in a full cycle is cell dependent
