cellular respiration Flashcards
both cellular respiration with oxygen and fermentation without oxygen begin with…
glycolysis
to begin the reaction of both cellular respiration with O2 and fermentation, how many molecules of ATP are used to provide activation energy?
4
just know that 2 ATP molecules are produced, making the “net amount of ATP produced 4 molecules” (like addition or sumn shit)
yessir
catabolism
breaking down
most CO2 from catabolism is released during the what…
the Krebs cycle
aerobic respiration means with…
oxygen
the sequence of events of aerobic respiration begins with… (in which a molecule of glucose of broken into two molecules of pyruvate in the cytosol)
glycolysis
the second process of aerobic respiration is…
the Krebs cycle (in which carbons are liberated and join with O2 to form CO2 (the remaining hydrogens separate into H+ and e-)
the e- move from protein to protein in the what…?
ETC or electron transport chain (releases energy to be used for the active transport of H+ into the inner membrane space of the mitochondria)
H+ flow back into the matrix fluid through ATP Synthase in a process called…
chemiosmosis
at the end of the ETC, what is the final electron acceptor in aerobic oxidative phosphorylation?
oxygen
without [blank] the ETC would stop and ATP could not be made
oxygen
the e- of FADH2 are transferred through how many complexes of the ETC?
3
complexes of the ETC and NADH e- are transferred through how may complexes of the ETC?
4
which produces more ATP: FADH2 (3) or NADH (4)?
NADH
chemiosmosis in the mitochondria inner membrane PRODUCES…
heat goddamn it
the ability to complete cellular respiration with molecules other than glucose is considered…
fitness shit
instead of glucose, amino groups can be removed or what’s the other word??
deaminate and enter the Krebs cycle
“aerobic prokaryotes do not have mitochondria, but can move H+ across plasma membranes. INCREASED surface area provides more space for reactions to occur”
makes sense bc an increased surface area = more space = more reaction, duh
“when inadequate oxygen is supplied to muscle tissue, [blank] results in a buildup of [blank] in the muscles”(double whammy w this one)
results in a buildup of FERMENTATION and results in LACTIC ACID, as it goes hand-in-hand
for instance, as contracting a virus results in the INCREASE of lactic acid production in the cells, ATP production will DECREASE
the person will feel tired bc fermentation in the CYTOSOL produces LESS ATP compared to aerobic cellular respiration in the MITOCHONDRIA
yeast population GROWING = rapid rate of mass loss
this was a diagram n shit but “the day 11 onwards, the substrate runs out and the ETHANOL kills the remaining yeast”
