Study Notes
- A diagram of the mitochondria should be able to be labeled with the following parts:
- Inner Membrane
- Outer Membrane
- Matrix
- DNA
- Cristae
Cellular Respiration Equation
- Chemical Formula: 6O2 + C6H12O6 —---> 6CO2+ 6H2O +32 ATP
- Word Equation: Oxygen + Glucose —--> Carbon Dioxide + water + ATP
Relationship to Photosynthesis:
- The inputs (reactants) of Photosynthesis are the outputs (products) of cellular respiration.
Aerobic vs. Anaerobic Respiration
- Aerobic respiration requires oxygen.
- Anaerobic respiration doesn’t use oxygen.
- Aerobic respiration produces more ATP than anaerobic respiration.
Organisms and Necessity
- Most eukaryotic organisms perform cellular respiration.
- Cells need to perform cellular respiration to produce energy in the form of ATP.
- ATP is used to do cellular work.
Aerobic Respiration Sequence of Events
- Glycolysis
- Krebs Cycle
- Electron Transport Chain
Aerobic vs. Anaerobic Advantage
- Aerobic respiration makes much more ATP than anaerobic respiration.
Glycolysis
- Location: Cytoplasm
- Inputs: 2 ATP, Glucose, 2NAD
- Outputs: 2 ATP, Pyruvate, 2 NADH
Krebs Cycle
- Location: Mitochondria (Matrix)
- Inputs: Pyruvate, NAD, ADP
- Outputs: 2 ATP, 6 CO2, 8 NADH
Electron Transport Chain
- Location: Mitochondria (Cristae)
- Inputs: NADH, Oxygen
- Outputs: H2O, 32 ATP, NAD
- Function of oxygen: Combines with an electron from the ETC and hydrogen to form water.
Factors Affecting Aerobic Respiration Rate:
- Light intensity
- Color of light
- Temperature
- Carbon dioxide concentration
Anaerobic Respiration - Fermentation
- Purpose: To make ATP when oxygen is not available.
Fermentation Usage:
- Alcoholic fermentation makes alcoholic beverages.
- Lactic Acid fermentation makes yogurt, cheese, and other food products.
- Two types: Lactic Acid vs. Alcoholic
- Inputs: pyruvate
Outputs:
- Alcoholic fermentation produces CO2 and ethanol (alcohol).
- Lactic Acid fermentation produces lactic acid.
Organisms that use Fermentation:
- Alcoholic fermentation is used by yeast.
- Lactic acid fermentation is used by human muscle cells and some bacteria.
