What does it do?What does it do?

Uses glucose to create ATP

•How do plants get glucose?•make it themselves (autotroph)

•How do animals get glucose?•consume it (heterotroph)

What organelle

makes energy?

Mitochondria!

MitochondriaMitochondria

Mitochondria provide eukaryotic cells with energy

Mitochondria contain small pieces of DNA!

what organelle contains the full set of DNA?

Mitochondrial structures:Mitochondrial structures:

•Inner membrane

•Outer membrane

•Intermembrane space

•Cristae

•Matrix

StructuresStructures

Outer membrane: phospholipid bilayer, regulates what enters and exits the cell (semi-permeable)

Outer membrane: phospholipid bilayer, regulates what enters and exits the cell (semi-permeable)

•Inner membrane: freely permeable only to oxygen, carbon dioxide and water

StructuresStructures

•Intermembrane space: region between the inner and outer membranes, important for oxidative phosphorylation

•Cristae: folds of inner membrane, increases surface area between matrix and membrane

•Matrix: contains enzymes that are responsible for a multitude of reactions
