ADP, ATP and Cellular Respiration
Energy used by all Cells
Organic molecule containing high-energy Phosphate bonds
Chemical Structure of ATP
It supplies YOU with ENERGY!
How Do We Get Energy From ATP?
By breaking the high- energy bonds between the last two phosphates in ATP
What is the Process Called?
HYDROLYSIS (Adding H2O)
How Does That Happen?
How is ATP Re-Made?
The reverse of the previous process occurs.
Another Enzyme is used!
When is ATP Made in the Body?
During a Process called Cellular Respiration that takes place in both Plants & Animals
Includes pathways that require oxygen
Glucose is oxidized and O2 is reduced
Glucose breakdown is therefore an oxidation-reduction reaction
Breakdown of one glucose results in 36 to 38 ATP molecules
Overall Equation for Cellular Respiration
6CO2 + 6H20 + e- + 36-38ATPís
C6H12O6 + 6O2
What Type of Process is Cellular Respiration?
An Oxidation-Reduction Process or REDOX Reaction
Oxidation of GLUCOSE --> CO2 + H2O (e- removed from C6H12O6)
Reduction O2 to H2O (e- passed to O2)
What Carries the Electrons?
NAD+ (nicotinadenine dinucleotide) acts as the energy carrier
NAD+ is a coenzyme
Itís Reduced to NADH when it picks up two electrons and one hydrogen ion
