Text Chapter 4: Cellular Respiration Flashcards
Glycolysis (inputs and outputs)
Inputs- 2 ATP, 2NAD+
Outputs- 4 ATP, 2NADH
Kreb’s Cycle (inputs and outputs)
Inputs- 2ADP, 6NAD+, 2FAD
Outputs- 2 ATP, 4CO2, 6NADH, 2FADH2
Electron Transport Chain (inputs and outputs)
inputs- 2NADH, 2NADH, 6NADH, 2FADH2, O2
outputs- water, 32 ATP
Structure of Mitochondrion and Regions involved in Cellular Respiration
Inner Membrane: Electron Transport Chain
Matrix: Krebs Cycle, Acetyl-CoA formation
Intermembrane Space: H+ ions accumulate
Crista= folds
Overall Gain of ATP from the Complete Breakdown of Glucose
36 ATP; 2 from glycolysis, 2 from Kreb’s cycle, 32 from the chain
Area where most ATP is Produced
electron transport chain, inner membrane of mitochondria, 32 ATP
Electron Carriers involved in the Breakdown of Glucose
NAD+, FAD
Chemiosmosis in Mitochondria
diffusion of protons through channel in ATP synthase gives energy for ATP synthesis
Fermentation v. Cellular Respiration
fermentation generates NAD+ to allow glycolysis to continue
Where Energy-Rich Molecules Enter the Glucose Pathway
in the cytoplasm under anaerobic conditions (no oxygen needed)
Factors that Influence Metabolic Rate
temperature
Cellular Respiration v. Photosynthesis
Cellular respiration starts with glucose and ends with CO2 and water, occurs in the inner membrane of the mitochondria
Photosynthesis starts with CO2, ends with glucose, occurs in chloroplast
Where can Lactic Acid be Converted back to Pyruvate
liver
When Brain cells use Glucose for Energy
in the presence and absence of carbohydrates
When Brain cells use Proteins for Energy
in the absence of carbohydrates
