31 - for every NADH that passes its electrons on to the electron transport chain , approximately how many ATP are produced from the ADP and phosphate ?
answer is 3.
----------------------------------------------------------------------------------------------------------
32 - isocitrate lyase cleaves isocitrate to succinate and __________ in the glyoxylate pathway ?
answer is glyoxylate .
------------------------------------------------------------------------------------------------------------
33 - in a net reaction of the citric acid cycle , what are the reactants ?
answer is ---------- 3 NAD + plus FAD plus GDP plus PHOSPHATE plus acetyl co A .
-----------------------------------------------------------------------------------------------------------
34 - which segment of the citric acid cycle is used in the glyoxylate pathway ?
answer is succinate to oxaloacetate .
----------------------------------------------------------------------------------------------
35 - gluconeogenesis takes place in the cytosol and the oxaloacetate must be converted for transport out of the mitochondrion .
the above statement is true .
----------------------------------------------------------------------------------------------------------
36 - which substrate in the citric acid cycle is coupled to the reduction of FAD to FADH2 ?
a- citrate
b- isocitrate
c- succinate
d- fumarate
answer is c .
-----------------------------------------------------------------------------------------------------------
37 - which enzyme complex of e coli is a particle of about 4600 kD , with a diameter of 300 .
answer is pyruvate dehydrogenase .
----------------------------------------------------------------------------------------
38 - when glucose is converted to lactate or ethanol , a relatively reduced product leaves the cell.
the above statement is true .
---------------------------------------------------------------------------------------------
39 - albert szent - gyorgyi found that cellular respiration is dramatically decreased by small amounts of succinate , fumarate , malate or oxaloacetate .
the above statement is false . the cellular respiration actually increases after adding these compounds .
------------------------------------------------------------------------------------------------------------------------
40 - the biosynthesis of which compounds uses the alpha ketoglutarate and oxaloacetate as starting materials ?
answer is amino acid biosynthesis .
