If you did a 10 minute wall sit, what would your muscles start to feel like? Why do they begin

to feel like that?

Purpose of Cellular Respiration

• To break down glucose in our cells to produce energy in the form of ATP

Glycolysis

• Input: Glucose

• Output: Pyruvate

• Location: Cytoplasm• Main Players: Glucose

• Significance: Allows 2 ATPs to be made as well as breaks the glucose molecule down into a more usable form

Kreb’s Cycle

• Input: pyruvate • Output: CO2, NADH, FADH2• Location: Happens in the mitochondria• Main Players: Carbon, NADH, FADH2• Significance: Makes 2 more ATPs and creates

lots of positive and negatives charges for the next step

Electron Transport Chain

• Input: NADH and FADH• Output: H20 and ENERGY!• Location: Happens in the mitochondria

• Major Players: Oxygen, Electrons, ATP synthase

Significance: Creates 32 ATPs, the majority of the energy for the cell!

Lactic Acid Fermentation

• Input: Pyruvate• Outputs: 2 ATPs and lactic acid

• Happens in the mitochondria

• Allows us to make small amounts of energy without oxygen

Alcoholic Fermentation

• Input: Pyruvate• Outputs: 2 ATPs, CO2, and ethanol

• Happens in the mitochondria

• Allows small amounts of energy to be made in yeast and bacteria cells without oxygen

Energy Tally

• 36 ATP for aerobic vs. 2 ATP for anaerobic

– Glycolysis 2 ATP

– Kreb’s 2 ATP

– Electron Transport 32 ATP Total: 36 ATP
