Purpose of Celluar respiration
Break down glucose into carbon dioxide and water to produce ATP
What are the major steps of cellular respiration
- Glycolysis
- Pyruvate Oxiudation
- Citric Acid cycle
- Oxidative phosphorylation
What are the electron carriers in cellular respiration
NAD+ and FAD
What do NAD+ and FAD become and when
NAD+ turns to NADH
FAD turns to FADH2
When they gain electrons
NAD⁺ + 2e⁻ + 2H⁺ → NADH + H⁺
Celluar respiration reaction
FAD + 2e⁻ + 2H⁺ → FADH₂
Celluar respiration reaction
Location of glycolysis
Cytoplasm
What’s the process of glycolysis
- Glucose (6-carbon) → 2 Pyruvate (3-carbon each)
- ATP produced
- NAD⁺ converted to NADH
What’s the oxygen requirement for Glycolysis
Can occur WITHOUT oxygen (Anaerobic)
Location of Pyruvate Oxidation
Mitochondrial Matrix
Process of pyruvate oxidation
- Pyruvate → Acetyl CoA (2-carbon molecule)
- CO₂ released
- NADH generated
Pyruvate oxidation oxygen requirement
Requires oxygen Indirectly.
Citric Acid cycle location
Mitochrondial matrix
Process of Citric acid cycle
Acetyl CoA combines with a 4-carbon molecule
- Cycle regenerates the 4-carbon molecule
- Produces ATP, NADH, and FADH₂
- CO₂ released
Oxygen requirement for Citric Acid cycle
Require oxygen indirectly
Location for Oxidative Phosphirylation
Innner mitochondrial membrane
Process of Oxidative Phosphorylation
NADH and FADH₂ deposit electrons into the electron transport chain (ETC)
- Electrons move through ETC, releasing energy to pump protons (H⁺) out of the mitochondrial matrix
- Creates a proton gradient
- Protons flow back into the matrix via ATP synthase, producing ATP
- Oxygen accepts electrons and protons to form water (H₂O)
Location for oxidative phosphorylation
Requires oxygen DIRECTLY
Location for fermentation
Cytoplasm
Process of Fermenation
Glycolysis can occur without oxygen by using fermentation.
The conversion of co enzymes of electron transport chain is where
across the membrane of the Krista
