Cellular Respiration Energy is released by breaking the bonds
of food molecules (such as glucose) to make ATP from ADP
ADP = adenosine diphosphate ADP + Pi ATP 2 types
aerobic respiration anaerobic respiration

Aerobic Respiration respiration that
requires oxygen starts in the cytoplasm
glycolysis moves to the
mitochondria Krebs Cycle Electron Transport
Chain

Aerobic Respiration C6H12O6 + 6O2 6CO2 + 6H2O
38 ATP are produced per molecule of glucose
2 ATP are used, so net ATP is 36 Some energy is lost to the environment
as heat exergonic reaction – energy is released

Cellular Respiration and ATP Glycolysis requires 2 ATP to begin and produces 4 ATP
as a result-net 2 ATP produced- Glucose is split into 2 Pyruvic Acid molecules
Krebs begins with the pyruvic acid molecules from glycolysis, breaks them down producing CO2 and high energy electrons netting 2 ATP in the process.
The electrons released during the Krebs cycle are brought to the Electron Transport Chain by electron carrying molecules NADH and FADH. The ETC nets 32 ATP per molecule of Glucose that starts off Cellular Respiration
The total production of ATP in Aerobic Respiration is 38 ATP, 2 are used up so 36 net.

Anaerobic Respiration takes place in the absence of oxygen Fewer ATP are produced – net ATP is 2 2 types
Lactic acid fermentation Alcoholic fermentation

Lactic Acid Fermentation Enzymes break down a glucose molecule
into two lactic acid molecules, transferring energy to ATP
C6H12O6 + 4ADP + 4Pi lactic acid + 4ATP
This process causesa burning sensation in muscle fatigue

Alcoholic Fermentation Enzymes break down a glucose molecule into
two molecules of ethanol and two molecules of CO2, transferring energy to ATP
C6H12O6 + 4ADP + 4Pi 2 ethanol + 2 CO2 + 4ATP This process is used…
to produce alcohol in gasoline additives baking
