In Cellular Respiration,electrons Are Moved Along a Series of Membrane

question 24

Multiple Choice

In cellular respiration,electrons are moved along a series of membrane proteins during the electron transport chain.If there was a mutation in the DNA coding for each of the proton pumps of the electron transport chain such that these proteins became non-functional,what would you predict to occur?

• A)Protons would not be moved from the matrix to the intermembrane space and so ATP synthase would not be activated.
• B)Protons would no longer be moved from the intermembrane space to the matrix and so ATP synthase would not be activated.
• C)NADH and FADH₂ would have to donate their electrons directly to ATP synthase in order for ATP synthesis to occur.
• D)All electrons would have to be stripped from water instead of NADH and FADH2 to create the proton gradient needed to power ATP synthase.
