Tan_Anson_Block4_MM6(Respiration)
Process of releasing energy for glucose(Chemical Stored Potential Energy)
Aerobic
Reactions controlled by enzymes
Occuring in plants and animals all the time
Uses Oxygen
Releases CO2 as byproduct
Digestion -------> Glucose
Glucose + Oxygen = CO2 +H2O+ Energy
the electron transport chain
Produces 2 ATP per FADH2 and 3 ATP per NADH
through oxidative phosphorylation
Final metabolic pathway
uses enzymes to oxidize nutrients
releases the energy from electrons to form ATP
Receives 10 NADH and 2 FADH2 for 3 other reactions
Produces 34 net ATP
Release energy from the electron to ATP
Occurs in the inner mitochondria matrix
Krebs Cycle
Release energy from the pyruvate(derived from glucose) to electrons
relays the electrons to coenzymes molecules(NADH and FADH2)
NAD+ and FAD each carries 2 electrons to the ETC
Anaerobic
Occurs in the cytoplasm
Glycolysis
releases energy to 2 ATP
breaks down glucose into 2 pyruvate and 2 NADH
Fermentation
evolved in anaerobic bacteria to empty NADH of electron which replenishes the NAD+
Produces ethanol or lactic acid and two NAD+
Required for/Energy is used for
to maintain a constant body temperature
muscle contraction
Build up large molecules to smaller ones
Proteins from amino acids
Reactions that occur in the mitochondria
Ex: Build sugars and nitrates(nutrients) into amino acid
When quick and abundant energy is needed during exercise
Flight or Fight Response with epipherine triggers it rapid breakdown of glycogen
Glycogen is glucose stored from food in the liver
Converted back to glucose for more energy
CO2 needs to removed faster
Demand for oxygen grows
Oxygen Debt
Forms when NAD+ needs to be replenished quickly
causes a buildup of lactic acid
Increases Entrophy
