Amazing ATP
Before you view this, don’t forget that EVERY step of this
process is facilitated by ENZYMES!

An Energized Phosphate Group

Glucose(Just ONE example of a molecule
ATP can transfer energy to)
P
P
Phosphate Group Phosphorylates
(Transfers Energy to)
GlucoseP
An intermediate molecule (Glucose
in this example) is activated.
P
Glucose has energy to “do
work” BUT Phosphate does
not
P
“Work”-Glucose now has energy to join a growing
chain of glycogen
P
WORK = New bond formed
P
Phosphate drifts away in the cell cytoplasm
A more complex molecule is formed
Phosphates Must Regain Energy From
Chemical Energy
Stored in Organic
Molecules.Some
examples?

Hello. I am…
An Organic Molecule.
Organic Molecules are Broken Down Through
Cell Respiration Releasing…

How much ATP is used?
• Every second approximately
10 million ATP molecules are used and regenerated per cell
