Cellular respiration 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 organisms can perform cellular respiration?
Where in a cell does cellular respiration occur? What organelle makes energy? Mitochondria!
Mitochondria Mitochondria provide eukaryotic cells with energy Mitochondria contain small pieces of DNA! what organelle contains the full set of DNA?
Structures Outer membrane: phospholipid bilayer, regulates what enters and exits the cell (semi-permeable) Inner membrane: freely permeable only to oxygen, carbon dioxide and water
Structures 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
Mitochondria All structures working together… Glucose is broken down and yields adenosine triphosphate, ATP!
How much ATP is yielded in aerobic respiration? 36 ATP
