Mitochondrion
The Powerhouse of the Cell
Mitochondrion
Tubular shaped organelle that is found in all
types of eukaryotic cells. Located in the
cytoplasm.
Bound by two membranes:
Smooth outer membrane
Inner folded membrane
Parts of Mitochondrion
Inner Membrane
Outer Membrane
Crista/Cristae- Folds of inner membrane
Matrix-Includes enzymes, Ribosomes, and DNA
Functions
To generate large quantities of energy in the form of
adenosine triphosphate (ATP)
Store calcium for cell signaling
Generate heat
Mediate cell growth and death
Similar function of a digestive system
~Takes in nutrients
~Breaks down those nutrients
~Creates energy for the cell
~This process is known as cellular respiration
Cellular Respiration
Allows organisms to use energy stored in the
chemical bonds of glucose (C6H12O6). The
energy in glucose is used to produce ATP. Cells
use ATP to supply their energy needs.
Mitochondrial Dysfunction
Parkinson's Disease- Dopamine
Epilepsy
Alzheimer’s
Muscular Dystrophy
Lou Gehrig’s
Cerebral Palsy
Autism
Diabetes
Mitochondrial Dysfunction
Energy production problem
Power plants in cell don’t work properly
Body has a power outage
Dysfunction can look different and is categorized
by many diseases
