the process by which mitochondria release energy by breaking glucose and other food molecules in the presense of oxygen
cellular respiration equation
C6H12O2 + 6O2 --> 6CO2 + 6H2O + ATP
glycolysis
converts glucose (6 oxygens) to pyruvic acid (3 oxygens)
creates 2 ATP
wastes: CO2
high energy electrond are carried by NADH (Nicotinamide adenine dinucleotide) to the ETC and chemiosmosis
Krebs cycle
in aerobic respiration
costs 2 ATP, creates 4 ATP, net gain of 2 ATP
gives off CO2
NADH and FADH2 (Flavin adenine dinucleotide) carry electrons to the ETC and chemiosmosis
ETC and Chemiosmosis
makes about 34 ATP
TOTAL ATP CREATED: 36 ATP
why does aerobic respiration produce more energy than anaerobic respiration?
anaerobic resporation completely breaks down the molecules to obtain the maximum amount of energy, anaerobic respiration does not fully break down the molecules
what are the differences between aerobic and anaerobic respiration?
aerobic respiration requires oxygen, anaerobic respiration does not
aerobic respiration produces 36 ATP, anaerobic respiration produces 2 ATP
lactic acid fermentation (anaerobic respiration)
1. glycolysis (2 ADP + 2 P --> ATP) (2 NAD+ --> 2NADH) created 2 pyruvic acid
