The Mighty Mitochondria

Created By: Khadija


Where am i found
Where Am I Found?

  • I have my own DNA (mDNA).

  • I am thought to have derived from a bacteria-like cell, which incorporated into eukaryotic cells.

    • Eukaryotic cells are cells with membrane bound organelles (cell parts) that have a formal nucleus.

  • I am found in eukaryotic cells, like plant and animal cells.

I am the powerhouse of the cell
I Am the “Powerhouse” of the Cell

  • I supply energy to the cell through the process of cellular respiration.

  • This occurs in my cristae (inner membrane).

  • The energy I produce is in the form of ATP (adenosine triphosphate).


How s the energy formed
How’s the Energy Formed?

  • ATP is formed in electron transport chain.

  • The ETC transfers protons (H+) from the inner compartment to the outer.

  • As the protons flow back to the inner compartment, the energy of their movement is used to add phosphate to ADP (adenosine diphosphate), forming ATP.

Without the mitochondria
Without the Mitochondria…

  • Cells wouldn’t have enough energy to survive.

Cardiac Cells


When your cells die
When Your Cells Die…

  • Tissues die.

Cardiac Tissue


When tissues die
When Tissues Die…

  • Organs fail.

Example: The Heart stops beating.


Without your organs functioning
Without Your Organs Functioning…

  • You’ll keel over and die.

If only I had enough energy to stay on the wall!


So why am i important
So Why Am I Important?

  • It’s all connected.

  • If one level fails, all levels fail.

  • You’re made of organ systems that are made of organs that are made of tissues that are made of cells that are made of organelles like me, the “Mighty Mitochondria.” If I fail, you fail, or should I say, die!
