Cellular Respiration Quiz Review Flashcards
biochemical pathway
series of reactions in which the products of one pathway become the reactants of another pathway
cellular respiration
a biochemical pathway that allows organisms to break down glucose to provide energy as ATP for the cell
ATP synthase
a protein/enzyme that synthesizes ATP
aerobic
uses oxygen
anaerobic
no oxygen
What three high-energy molecules are released from the Krebs Cycle?
ATP used for immediate energy, NADH goes to ETC, and FADH2 also goes to ETC
What are the products of LA fermentation?
Lactic acid and NAD+
What are the products of Alcoholic fermentation?
Alcohol, Carbon dioxide, and NAD+
What organisms perform LA fermentation?
most bacteria and other microorganisms, plants, animals, and most fungi
What organism performs Alcoholic fermentation?
yeast (a group of fungi)
How much ATP is generated from Alcoholic fermentation?
2
How much ATP does aerobic respiration create?
36
How much ATP does anaerobic respiration create?
2
What does glycolysis produce?
ATP, NADH, and 2 pyruvic acids
What does the Krebs Cycle produce?
CO2, 2 ATP, and the reactants for the ETC which are 8 NADH and 2 FADH2
How much ATP does the ETC produce?
32
Where does the Krebs Cycle happen?
matrix of the mitochondria
What part of aerobic respiration produces water?
ETC
How much ATP is generated from LA fermentation?
2
Where does the ETC take place?
inner membrane of the mitochondria
Where does glycolysis take place?
cytosol/cytoplasm of the cell
What are the two places NADH could come from?
glycolysis or Krebs Cycle
What does NADH do with the electrons it carries?
take them to the ETC to make a lot of ATP
What can NADH do if there is not enough oxygen or ATP is needed quickly?
convert to NAD+ through either kind of fermentation
What produces no ATP?
fermentation
What takes place without oxygen?
glycolysis, krebs cycle, and fermenation
Where is oxygen used directly to remove low energy electrons?
ETC
What pathways does yeast carry out to generate energy and produces alcohol and carbon dioxide as byproducts?
glycolysis and fermentation
