amino acid of the water trap in ATP synthase that bonds to the oxygen atom

lysine

The asymmetric shaft of the merry-go-round that produces the various states of the stationary, trimeric enzyme complex is called the ________.

gamma subunit

The a subunit's ________ attracts a negatively charged amino acid on the preceding c subunit and protonates and neutralizes that amino acid for progression into the phospholipid environment as the merry-go-round spins.

arginine

When the ATP synthase enzyme is in the ______, it withdraws H₂O from a trigonal bipyramid transition state to form ATP.

T state

When the ATP synthase enzyme is in the ______ it reforms a beta sheet and accepts ADP + Pi.

L state

The stationary protein that contains a half-channel for protons to the ATP synthase merry-go-round from the intermembrane space and a half-channel for protons going from the merry-go-round to the matrix is the _______.

a subunit

amino acid of the merry-go-round that donates protons to the matrix

glutamatic acid

negatively charged amino acid of the merry-go-round that is attracted forward to receive a proton channeled from the intermembrane space

glutamate

When the ATP synthase enzyme is in the ______, the asymmetric shaft disrupts a beta sheet to eject ATP.

O state

The merry-go round of ATP synthase in mammalian mitochondria is composed of 8 identical _______s.

c subunits
