in glycolysis, glucose molecule is converted intopyruvic acid
photorespiration in C3 plants starts starts fromphosphoglycerate
which of the following is the connecting link between glycolysis and krebs cycleacetyl Co A
pyruvate kinase enzyme catalysesthird irreversible step of glycolysis
an enzyme of TCA cycle are located in the mitochonrial matrix except one which is located in inner mitochondrial membrane in eukaryotes and in cytosol in prokaryotes. this enzyme issuccinate dehydrogenase
by which of the follwing complex, proton is pumped to reach ATP synthase to participate in ATP synthesiscytochrome b6f
in alcoholic fermentation, NAD+ is produced during thereduction of acetyldehye to ethanol
the bacterium (clostrium botulinum ) that cause botulism isan obligate anaerobe
net gain of ATP molecules during aerobic respiration is36 molecules
maximum amount of energy/ATP is liberated on oxidation offats
life without air will beanaerobic
phosphoenol pyruvate (PEP) is the primary CO2 acceptor inC4 plants
in which process CO2 is not releasedlactate fermentation
the energy releasing process in which the substrate is oxidised without an external electron acceptor is calledglycolysis
how many ATP molecules could maximally be generated from one molecule of glucose, if the complete oxidation of one mole of glucose to CO2 and H2O yields 686 kcal and the useful chemical energy available in the high energy phosphate bond of one mole of ATP is 12 kcalfifty seven
in alcoholic fermentationtriose phosphate is the electron donor while acetaldehyde is the electron acceptor
in animal cells the first step of glucose breakdown isglycolysis
out of 38 ATP molecules produced per glucose, 32 ATP molecules are formed from NADH/FADH2 inrespiratory chain
when one glucose molecule is completely oxidised, it changes30 ADP molecules into 30 ATP molecules
out of 36 ATP molecules produced per glucose molecule during respiration2 are produced outside mitochondria and 34 inside mitochondria
EMP can produce a total of8 ATP
NADP+ is reduced to NADPH inHMP
during which stage in the complete oxidation of glucose are the greatest number of ATP molecules formed from ADPelectron transport chain
which one of the following concerns photophosphorylationADP+inorganic PO4--(light energy)---->ATP
other name for tricarboxylic acid cyclecitric acid cycle
the mechanism of ATP formation both in chloroplast and mitochondria is explained bychemiosmotic theory of mitchell
in krebs cycle FAD participates as electron acceptor during the conversion ofsuccinic acid to fumaric acid
connecting link between glycolysis and krebs cycle is/ before entering krebs cycle pyruvate is changed intoacetyl co-A
which is essential to convert pyruvic acid into acetyl Co-A?LAA, TPP and NAD
poisons like cyanide inhibit Na+ efflux and K+ influx during cellular transport. this inhibitory effect is reversed by an injection of ATP. this demonstrates thatATP is the carrier protion in the transport system
end product of citric acid/ krebs cycle isCO2 and H2O
oxidative phosphorylation is production ofNADPH in photosynthesis
terminal cytochrome of respiratory chain which donates electrons to oxygen isCyt. a3
in germinating seeds fatty acids are degraded exclusively in theglyoxysomes
respiratory quotient quotient for fatty acids is<1
apparatus to measure rate of respiration and R.Q. isrespirometer
