Q 10 - Energy Generation part 2 Flashcards
ATP synthase enzyme produces ATP. If the entire 4-step aerobic respiration system is perfectly efficient, how much ATP is produced from one glucose molecule?
38
ATP synthase Phosphorylation (step 4) is powered by…
the pool of H+ concentrated in the intermembrane space
The end of the ETC in complex 4 means electrons are acted upon by _________, accepted by _______ and forms __________
copper, O2, H20
T/F In addition to moving electrons Complexes 1,3,4 also pump H+ into the intermembrane space
True
Cytochrome C transports an electron between Complex ________ & ________
3 & 4
When ubiquinone is converted to ubiquinol, what takes place next?
ubiquinol transports electrons via hydrogen to complex 3
What is the function of Fe-S clusters in complexes 1, 2, 3?
they transport electrons
Why is the concentration gradient between the matrix and inter-membrane space so useful?
it allows a huge potential energy difference measured as PH between the two spaces
The intermembrane space is a storehouse for what in particular?
H+ ions
T/F Ubiquinol in complex 3 is quickly broken down & deficiencies of ubiquinone can form very quickly
False
Complexes 1 & 2 contribute what to the ETC?
electrons
The ETC’s basic function is to…
transport electrons through membrane proteins which then produce H+
When a hydrogen atom, written as H+, is indicated in biochemistry this is an _______________ & a _______________
electron and a proton
The ETC is located in the mitochondrion’s ________/ _____________- __________
cristae/ inner-membrane
T/F The 4 steps of molecule replication takes plce in the cell membrane
False
