Why do cells need energy?

Cells need energy to: move, grow,

make molecules, reproduce, etc

What does the cell use for energy?

ATP: molecule that cells use as a form of

usable energy

What does the cell use for energy?

ATP: molecule that cells use as a form of

usable energy

Analogy at RKMS:

ATP is like the electricity that our school uses

as usable energy

Where do we get ATP?

Our body breaks down food to make ATP

Glucose (sugar) ATP

Food Glucose ATP (energy

molecule)

Machine only takes quarters, not bills

Cells only take ATP, not glucose

Why do cells need ATP? Why not

just use glucose or food directly?

glucose ATP

Where does this happen?

Mitochondria: where glucose ATP

Where does this happen?

Mitochondria: where glucose ATP

RKMS analogy: The mitochondria is where

energy gets made like the electric box
