OBJ: describe the structure and function of ATP/ADP
OBJ: state and explain the reactants, products, and energy yield
(ATP of aerobic respiration)
 Cell Respiration is the process of breaking the
chemical bonds of GLUCOSE (a simple carbohydrate)
to release ENERGY for life.
 Breaking chemical bonds releases electrons.
 C6H12O6 + 6O2  6CO2 + 6H2O + ENERGY
Glucose + Oxygen  Carbon Dioxide + Water + Energy
 Energy = ATP: Adenosine
Triphosphate
 ATP is our bodies USABLE
source of energy.
 Energy = ATP: Adenosine
Triphosphate
 ATP is our bodies USABLE
source of energy.
 Energy is stored in the bonds
between the phosphates.
 Energy = ATP: Adenosine
Triphosphate
 ATP is our bodies USABLE
source of energy.
 Energy is stored in the bonds
between the phosphates.
 When a phosphate is broken
off ATP, it releases energy
and become ADP (adenosine
Diphosphate)
 Aerobic cellular Respiration uses OXYGEN.
 Anaerobic cellular respiration does NOT use oxygen.
OBJ: describe the process for aerobic cellular respiration,
location of processes within the cell and energy yield
(glycolysis, Kreb's cycle, Electron Transport Chain)
 Step 1 Glycolysis
 Occurs in the CYTOPLASM of the Cell.
 Breaks GLUCOSE into 2 PYRUVATE molecules so that
they can fit through the membrane of the
MITOCHONDRIA.
 Releases enough energy to make 2 ATP.
GLUCOSE
2 PYRUVATE
 Step 2: Krebs Cycle (citric acid cycle)
 Occurs in the MATRIX.
 Releases enough energy to make 2 ATP and makes 6
CO2.
 Electron Carriers:
 6 NADH
 2 FADH2
 Step 3: Electron Transport Chain
 Occurs on the inner membrane of the
MITOCHONDRIA.
 All the electrons from glucose travel to the inner
membrane of the mitochondria.
 Step 3: Electron Transport Chain continued…
 Each time an electron is passed from one electron
carrier to the next, enough ENERGY is released to make
1 ATP.
 This happen 32 times to make 32 ATP.
 The last electron carrier to receive the electron is
OXYGEN which quickly combings with 2 hydrogens to
make H2O.
 Step 3: Electron Transport Chain continued…
 The last electron carrier to receive the electron is
OXYGEN which quickly combings with 2 hydrogen’s to
make H2O.

respiration.
OBJ: compare and contrast lactic acid and alcohol fermentation
 Contains only 2 steps and takes place in: BACTERIA,
YEAST, or MUSCLE CELLS when OXYGEN is lacking.
 Glycolysis
 Fermentation

 Fermentation:
 Alcohol Fermentation
 Occurs in BACTERIA and YEAST
 Occurs in the CYTOPLASM of the cell.
 Makes 0 ATP and produces 2CO2 and 2 ETHANOL
 Contains only 2 steps and takes place in: BACTERIA,
YEAST, or MUSCLE CELLS when OXYGEN is lacking.
 Glycolysis
 Fermentation:
 Alcohol Fermentation
 Occurs in BACTERIA and YEAST
 Occurs in the CYTOPLASM of the cell.
 Makes 0 ATP and produces 2CO2 and 2 ETHANOL
 Lactic Acid Fermentation
 Occurs in MUSCLE cells when OXYGEN levels are low.
 Occurs in the CYTOPLASM of the cell.
 Makes 0 ATP and 2 LACTIC ACID.
OBJ: compare and contrast aerobic and anaerobic respiration
 Total ATP:
 Aerobic cell respiration: 36
 Anaerobic cell respiration: 2
