Cellular Respiration

Term and or QuestionDefinition and or Answer
Glycolysis In and Out In- Glucose, ADP, NAD Out- ATP (2), NADH, Pyruvic Acid
Krebs Cycle In and Out In- Pyruvic Acid, ADP, NAD+ (4), FAD Out- NADH (4), FADH2, ATP (2), CO2 (3)
ETC In and Out In- NADH, FADH2, ADP, O2 Out- NAD+, FAD, ATP (34), H2O
How many carbon atoms are in one molecule of glucose? 6
How many carbon atoms are in one molecule of Pyruvic Acid? 3
The the process of glycolysis, what happens after it crosses the cell membrane into the cytoplasm of the cell? It turns into Pyruvic Acid (2)
How many ATP molecules are produced during glycolysis 2
Hydrogen-carrying molecules are produced during... Glycolysis
Does glycolysis occur inside or outside the mitochondria Outside
What happens to Pyruvic Acid during the Krebs Cycle Turns into CO2 (breaks down into 3)
Where does Pyruvic Acid turn into CO2? Inside mitochondria/floating in mitochondrial matrix
What two hydrogen-carrying molecules are formed during Krebs Cycle NADH & FADH2
What cell structure is the site for the electron transportation chain Mitochondrial matrix
What substance do the carrier proteins transport across the inner mitochondrial membrane e- (energy) & Hydrogen (positive)
What high energy molecules are formed by the electron transport chain ATP
What atom accepts the hydrogen ion at the end of the electron transport chain Oxygen
What molecule is formed as a product of oxygen accepting the hydrogen ion H2O
Why do the events of the electron transport chain constitute an aerobic process rather than an anaerobic process like glycolysis Because it has O2
Compare the ATP available to cells when oxygen is present versus when it is absent. How might this help explain why brain and heart functions are so quickly affected when a person cannot breathe? With so little ATP, the cells would die and not make it to the brain and heart
What substances may be formed in anaerobic respiration Lactic acid, pyruvic acid, oxygen, and alcohol
Recall that two molecules of ATP are formed during glycolysis. Neither fermentation process create any more ATP. What would you predict about the solar energy available to organisms that carry out fermentation The energy will be very low and fermentation can’t be done
What is the relationship between overexertion of muscles in the formation of lactic acid. How does this relate to the burn felt during strenuous activity If I work out, and don’t stretch, the lactic acid burns my muscles
Foods that have fermentation process Alcohol Bread Pickled food Soy sauce
