Amazing ATP

Before you view this, don’t forget that EVERY step of this

process is facilitated by ENZYMES!

Glucose(Just ONE example of a molecule

ATP can transfer energy to)

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

Molecules.Some

How much ATP is used?

• Every second approximately

10 million ATP molecules are used and regenerated per cell
