Define the process of aerobic respiration
energy rich molecules are degraded chemically with the generation of phosphate bond
energy in ATP molecules; electrons from the energy-rich initial reactant end up
combined with oxygen to form water
List the reactant and products for the over-all process of aerobic respiration
C6H12O6 Glucose(energy rich) + 6O2 Oxygen(energy poor) + 36 ADP(energy poor) =
6CO2 Carbon Dioxide(energy poor) + 6H2O Water(energy poor) + 36 ATP(energy rich)
List three stages of aerobic respiration
Glycolysis
Krebs Cycle
Electron Transfer Phosphorylation
List and describe the reactants and products of glycolysis
Pyruvate- a three carbon carbohydrate product of glycolysis whose continued
degradation generates two-carbon fragments that serve as reactants in the Krebs cycle
NADH- (nicotinamide adenine dinucleotide) a biomolecule that accepts electrons from
reactants in glycolysis and the Krebs cycle and transports them in solution to an
electron transfer system.
List and describe the reactants and products of the Krebs Cycle
Acetyl-CoA- a two carbon fragment resulting from degradation of pyruvate; the fragment
is attached to a large cofactor molecule that transfers the acetyl fragment onto a
reactant in the Krebs cycle
FADH2 (flavin adenine dinucleotide)- a biomolecule that accepts electrons from
reactants in the Krebs cycle and transports them in solution to an electron transfer
system. The system accepts all electrons and uses them to generate ATP for the cell
List and describe the reactants and products of electron transfer
ATP synthase- a protein within the mitochondrial membrane; it relieves a proton
gradient by allowing protons to flow back across the membrane. It uses the resulting
energy production to phosphorylate ADP making energy-rich ATP molecules
Calorie- the amount of energy required to raise the temperature of 1 gram of water by 1
degree Celcius
Explain the value of each of the three major parts of aerobic respiration to the
overall process
Explain the importance of fermentation in the living world
Describe the process of fermentation and the role ethanol plays therein
Define the role that autotrophs play in the living world
Define the process of photosynthesis and explain its role in energy flow in the
living world
