cellular respiration

• what is cellular respiration

  process by which organisms garner energy from food in a usable form -> breakdown of glucose into CO2
• what is the basic reaction for cellular respiration

  C6H12O6 + O2 → CO2 + H2O
• what is the inputs, outputs, location and purpose of glycolysis

  PURPOSE: break glucose into 2 3-carbon pyruvate molecules

  LOCATION: cytosol

  glucose → 2 pyruvate

  2 ADP + Pi → 2 ATP

  2 NAD+ → 2 NADH
• what is the inputs, outputs, location and purpose of the link reaction

  PURPOSE: convert pyruvate to Aceytl-CoA

  LOCATION: cytosol

  2 pyruvate → 2 Acetyl-CoA, 2 CO2

  2 NAD+ → 2 NADH
• what is the inputs, outputs, location and purpose of the kreb's cycle

  PURPOSE: break down Acetyl-CoA to CO2 + aim to produce NADH + FADH2

  LOCATION: mitochondrial matrix

  2 Acetyl-CoA → 4 CO2

  2 ADP + Pi → 2 ATP

  6 NAD+ → 6 NADH

  2 FAD + 4 H+ → 2 FADH2
• what is the inputs, outputs, location and purpose of the electron transport chain

  PURPOSE: produce most ATP 

  LOCATION: cristae

  O2 → H2O

  26/26 ADP + Pi → 26/28 ATP

  10 NADH → 10 NAD+

  2 FADH2 → 2 FAD
• what are the inputs, outputs, location and purpose for anaerobic fermentation in yeast (alcohol)

  PURPOSE: produce ethanol from glucose

  LOCATION: cytosol

  
  

  2 pyruvate → 2 ethanol, 2 CO2

  2 NADH → 2 NAD+
• what is the process of anaerobic fermentation in animals (lactic acid)

  glucose → 2 lactic acid + 2 ATP

  1. glycolysis →  2 net ATP glucose → 2 pyruvate
  2. lactic acid fermentation →regenerate NAD+

  2 pyruvate → 2 lactic acid 

  2 NADH → 2 NAD + 
• what is the process of anaerobic fermentation in yeast (alcohol)

  glucose → 2 ethanol + 2 CO2 + 2 ATP

  1. glycolysis →  2 net ATP glucose → 2 pyruvate
  2. alcohol fermentation →  regenerate NAD+

  2 pyruvate → 2 ethanol + 2CO2 

  2 NADH → 2 NAD + 
• what are the factors that affect cellular respiration

  • temperature

  A) pH

  B) temperature

  C) glucose availability

  D) oxygen concentration
