cellular respiration Flashcards
(21 cards)
anerobic cellular respiration is what?
Glycolysis (produces 2 ATP)
aerobic cellular respiration uses?
oxygen and produces 36 ATP
the process of converting stored chemical energy to usable energy in the form of?
ATP
ATP can be broken down to release energy when?
a phosphate is released
what is the cellular respiration formula?
glucose + oxygen —> carbon dioxide + water + energy
C6 H12 O6 + 6O2 —> 6CO2 + 6H2O + ATP
how many carbon molecules are in a single pyruvate
3
after glycolysis if O2 is not present what happens to the produced pyruvates and what happens in them?
they go to fermentation where it can be lactic acid fermentations and turned into lactic acid/lactate or alcoholic fermentation where it turns to ethanol+CO2
what is the net gain from glycolysis?
4 ATP gained 2 ATP lost 2 total gained
2NADH
2Pyruvates
What is the net gain from the Krebs Cycle?
2 ATP
2 FADH2
8 NADH
how many H+ are pumped into the intermembrane space from a FADH2 during the electron transport chain
2
How many H+ are pumped into the intermembrane space from NADH during the electron transport chain?
3
where does ETC/oxidative phosphorlation occur?
inner membrane of the mitochondria
where does glycolysis occur?
cytoplasm
where does the krebs cycle occur?
matrix of mitochondria
how much ATP does anaerobic respiration create?
2
how much ATP does aerobic respiration create?
34-36
during an energy change what percent of energy is lost in what form of heat each time there is a change in energy?
60% energy lost as heat energy
per glucose what is the net gain from the pre krebs reaction?
2 NADH
what is the name of the enzyme that creates ATP?
ATP synthase
what is the name of the molecule that creates NADH in the Krebs reaction
acetyl CoA which is a 2 carbon compound
