Week 6: Respiration and Fermentation Flashcards
(20 cards)
Atp definition
The common energy carrier of cells
Cellular Respiration
breaks down carbohydrates and other metabolites with the concomitant buildup of ATP
Cellular Respiration Stages
Glycolysis, The Krebs Cycle, The Electron Transport Chain
Glycolysis occurs in
the cytoplasm of cell
Glucose is
broken down into 2 molecules of Pyruvic Acid
Glycolysis :
NADH is
produced and carries the high energy electrons to the ETC(last step).
Krebs cycle location
matrix of mitochondria
NADH and FADH2 carry
high energy electrons
Electron Transport Chain location
cristae (inner membranes) of the mitochondria
The electron carries
NADH and FADH2
H+ions move through
ATP synthase channel to generate the ATP
Fermentation
an aerobic process
Disadvantage of fermentation
End products: toxic to cells
Disadvantage of fermentation reason 2
blood can’t remove all lactate—>muscle fatigue
Disadvantage of fermentation reason 3
O2 is needed to restore ATP levels and rid the body of lactate—> oxygen debt
Disadvantage of fermentation reason 4
efficiency: far less efficient than the complete breakdown of glucose
Advantages of fermentation
Provides a quick burst of ATP energy for muscular activity
Advantages of fermentation reason 2
Helps produce numerous food products
Advantages of fermentation reason 3
Yeast fermentation
Advantages of fermentation reason 4
Bacterial fermentation
