Cellular Respiration: Aerobic and Anaerobic Processes

Cellular respiration is the process by which cells break down glucose to produce energy in the form of ATP. There are two main types: aerobic (with oxygen) and anaerobic (without oxygen).

Key points:

  • Aerobic respiration produces 38 ATP molecules per glucose molecule
  • Anaerobic respiration (fermentation) produces only 2 ATP molecules
  • Both processes begin with glycolysis in the cytoplasm
  • Aerobic respiration continues in the mitochondria with the Krebs cycle and electron transport chain
  • Anaerobic respiration occurs only in the cytoplasm and results in either lactic acid or ethanol as waste products

Krebs Cycle and Electron Transport Chain

The Krebs cycle, also known as the citric acid cycle, is the second stage of aerobic respiration. It occurs in the mitochondrial matrix and generates NADH and FADH₂, which are used in the electron transport chain.

Key steps of the Krebs cycle:

  1. Acetyl-CoA enters the cycle
  2. Citric acid is formed
  3. CO₂ is released in two steps
  4. NADH and FADH₂ are produced
  5. One ATP is generated through substrate-level phosphorylation

Highlight: The Krebs cycle produces 2 ATP, 6 NADH, and 2 FADH₂ molecules per glucose molecule.

The electron transport chain (ETS) is the final stage of aerobic respiration, occurring in the inner mitochondrial membrane. It uses the NADH and FADH₂ produced in earlier stages to generate a large amount of ATP through oxidative phosphorylation.

Vocabulary: Oksidatif fosforilasyon (Oxidative phosphorylation) is the process of ATP production using the energy from electron transfer in the ETS.

Key points of the electron transport chain:

  • Electrons from NADH and FADH₂ are passed through a series of protein complexes
  • Oxygen is the final electron acceptor, forming water
  • A proton gradient is created across the inner mitochondrial membrane
  • ATP synthase uses the proton gradient to produce ATP

Highlight: The ETS produces approximately 34 ATP molecules, making it the most productive stage of cellular respiration.

Comparison of Aerobic and Anaerobic Respiration

Aerobic respiration and anaerobic respiration are two types of cellular respiration with significant differences in their processes and outcomes.

Key differences:

  1. Oxygen requirement:

    • Aerobic respiration requires oxygen
    • Anaerobic respiration occurs without oxygen

  2. Location in the cell:

    • Aerobic respiration occurs in both cytoplasm and mitochondria
    • Anaerobic respiration occurs only in the cytoplasm

  3. ATP yield:

    • Aerobic respiration produces 38 ATP molecules per glucose
    • Anaerobic respiration produces only 2 ATP molecules per glucose

  4. End products:

    • Aerobic respiration produces CO₂ and H₂O
    • Anaerobic respiration produces either lactic acid or ethanol and CO₂

  5. Efficiency:

    • Aerobic respiration is more efficient in energy production
    • Anaerobic respiration is less efficient but faster

Highlight: The main difference between oksijenli ve oksijensiz solunum (aerobic and anaerobic respiration) is the presence or absence of oxygen and the amount of ATP produced.

Nutrient breakdown in cellular respiration:

  • Carbohydrates are broken down into monosaccharides
  • Proteins are broken down into amino acids
  • Fats are broken down into fatty acids and glycerol

These molecules enter the respiratory pathway at different stages depending on their carbon content:

  • 6C molecules enter at glycolysis
  • 3C molecules enter as pyruvic acid
  • 2C molecules enter as acetyl-CoA

Example: Glycerol (3C) from fat breakdown enters the respiratory pathway as pyruvic acid, while fatty acids (2C units) enter as acetyl-CoA.

In conclusion, understanding the differences between aerobic and anaerobic respiration is crucial for comprehending cellular energy production in various organisms and conditions.

Glycolysis and Types of Cellular Respiration

Glycolysis is the first stage of cellular respiration, occurring in the cytoplasm of all cells. It breaks down glucose into pyruvic acid, producing a small amount of ATP and NADH.

Definition: Glikoliz (Glycolysis) is the process of breaking down glucose into pyruvate, occurring in the cytoplasm and common to both aerobic and anaerobic respiration.

Key points of glycolysis:

  • Occurs in the cytoplasm
  • Does not require oxygen
  • Produces 2 ATP and 2 NADH molecules
  • Ends with pyruvic acid formation

Aerobic respiration continues after glycolysis in the mitochondria, using oxygen to produce a large amount of ATP.

Highlight: The equation for oksijenli solunum (aerobic respiration) is: Glucose + 6O₂ → 6H₂O + 6CO₂ + 38 ATP + Heat

Anaerobic respiration (fermentation) occurs when oxygen is not available and produces either lactic acid or ethanol as waste products.

Example: Lactic acid fermentation: Glucose → 2 Lactic Acid + 2ATP + Heat + NAD⁺

Example: Alcoholic fermentation: Glucose → 2 Ethanol + 2CO₂ + 2ATP + Heat + NAD⁺

Vocabulary: NADH₂ (Nicotinamide Adenine Dinucleotide) is a coenzyme that carries electrons in cellular respiration.
