Cell Respiration (Final Review)

Role of NADH in respiration

Carries electrons to the Electron Transport Chain to help make ATP

Location of glycolysis

Cytoplasm

Location of the Krebs Cycle

Mitochondrial matrix

What happens to pyruvate before Krebs Cycle

Converted into Acetyl CoA

Location of Electron Transport Chain

Inner mitochondrial membrane

Role of Electron Transport Chain

Makes most ATP in aerobic respiration using electrons and H+

What happens to most energy released during respiration

Stored in ATP

Organisms using alcoholic fermentation

Yeasts and microorganisms

Organisms using lactic acid fermentation

Human muscle cells

Aerobic vs Anaerobic ATP production

Aerobic respiration makes more ATP than anaerobic

Lactic acid fermentation (reactants and products)

Pyruvic Acid, NADH → Lactic Acid, NAD+

Alcoholic fermentation (reactants and products)

Pyruvic Acid, NADH → Ethyl Alcohol, NAD+, CO₂

When do human cells use anaerobic respiration?

During intense exercise; can't last long because not enough ATP is made

Cellular respiration equation

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP

Where glucose comes from

Carbohydrates in food and drink

Where oxygen (O₂) comes from

Breathed in from the atmosphere

Where carbon dioxide (CO₂) comes from

Made during Krebs Cycle

Where water (H₂O) comes from

Produced in Electron Transport Chain

Where ATP comes from

Glycolysis, Krebs Cycle, and ETC
