Study Notes
- Cell respiration has three steps. It is important to know the amount of ATP and NADP generated in each step.
Glycolysis
- Produces (2 ATP, 2 NADH).
Krebs Cycle
- Produces (2 ATP, 6 NADH, 2 FADH2).
Electron Transport Chain
- Produces (28-34 ATP, 0 NADH).
- Glycolysis products are part of cell respiration and fermentation.
- Glycolysis breaks down glucose into 2 pyruvate molecules, resulting in 2 ATP and 2 NADH.
- It partakes in cell respiration (with oxygen) or fermentation (without oxygen).
- Cellular respiration is an exergonic reaction
- Food’s purpose is for biosynthesis and energy for cells.
- Pyruvic acid comes from glucose.
- Glycolysis quickly makes ATP
Oxidation
- Loss of electrons.
Reduction
- Gain of electrons.
- Cellular respiration occurs in the mitochondria.
- Energy from glucose transfers to the electrons.
- The equation for cellular respiration = (C6H12O6 +6 О2 —---> 6CO2 +6H2O +ATP)
- Carbon dioxide and water + light make sugars (glucose) in photosynthesis.
Citric Acid Cycle
- The Krebs Cycle produces:
- 2 ATP
- 6 NADPH
- 2 FADH2
Electron Transport Chain
- Produces
- 28-34 ATP
- No NADPH or FADH2
- Chemiosmosis involves ATP synthase
- It generates ATP from H+ protons moving from the intermembrane space into the mitochondrial matrix.
Cell Respiration
- Reactants:
- Glucose
- Oxygen
- Products:
- Carbon Dioxide
- ATP
- Water
- Oxygen is the final electron acceptor and forms water.
Krebs Cycle
- Products of Krebs cycle:
- 6 NADH
- 2 FADH
- 2 ATP
- Products of the electron transport chain are water and ATP.
- Fermentation involves glycolysis and the conversion of NADH back (oxidizes) to NA.
Fermentation
- Two types
- Alcoholic- ethanol
- Lactic- fungi
- Products of cellular respiration are carbon dioxide and water.
- Acetyl COA delivers two carbon acetyl groups to the Krebs or Citric Acid Cycle
- This forms citrate that will eventually form ATP.
- A total of 32-36 ATPs are generated in cellular respiration.
