Cellular Respiration
Aerobic Respiration: Oxygen is needed Aero = air
What type of organism uses this? Eukaryotes (plants and animals)
Stage 1. Glycolysis
Where it happens: Cytoplasm
What goes in Glucose from food
What comes out ATP, Pyruvate
ATP yield 2
​
Stage 2. Krebs Cycle or Citric acid Cycle
Where it happens: Mitochondria “matrix” are inside inner membrane
What goes in: Pyruvate
What comes out: Carbon Dioxide 2 ATP8 NADH 2FADH 2
ATP yield 2
​
Stage 3. Electron Transport Chain
Where it happens: Inner Membrane of Mitochondria
What goes in: NADH FADH2
What comes out: Atp water
ATP yield: 34

Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions. Cellular respiration takes place in the cells of animals, plants, and fungi, and also in algae and other protists.
Anaerobic Respiration: No oxygen needed
What type of organism uses this? Prokaryotes (Bacteria)
​
stage 1 - glycolysis
This happens in Cytoplasm
What goes in- Glucose from food
What comes out- ATP, Pyruvate
ATP yield- 2
What if no O2 is available?
FERMENTATION:
Does not make ATP itself, allows glycolysis to continue to make ATP
In yeast: Pyruvate🡪 Alcohol and Carbon Dioxide
In muscles: Pyruvate🡪 . Lactic Acid
Runners-glucose was split by glycolysis, but no oxygen available. Allows Glycolysis to continue to make ATP, but lactic acid builds up
