Biochemical Processes in Chapter 17
Chapter 17 delves into the intricate biochemical processes that underpin life. These processes involve the conversion of nutrients into energy and building blocks for cellular components. Understanding these pathways is crucial for comprehending how organisms function and maintain homeostasis.
Metabolic Pathways
Metabolic pathways are interconnected sequences of enzymatic reactions that transform molecules. These pathways include:
- Glycolysis: Breakdown of glucose to produce pyruvate and energy (ATP).
- Krebs cycle (Citric acid cycle): Oxidation of acetyl-CoA to produce CO2, ATP, and reducing equivalents (NADH and FADH2).
- Electron transport chain: Transfer of reducing equivalents from NADH and FADH2 to oxygen, generating a proton gradient used for ATP synthesis.
- Fatty acid oxidation: Breakdown of fatty acids to produce acetyl-CoA, which can enter the Krebs cycle.
- Gluconeogenesis: Synthesis of glucose from non-carbohydrate sources (e.g., amino acids, fatty acids).
Regulation and Control
Metabolic pathways are tightly regulated to ensure efficient energy production and avoid imbalances. Control mechanisms include:
- Allosteric regulation: Enzymes are activated or inhibited by the binding of small molecules.
- Feedback inhibition: End products of a pathway inhibit earlier enzymes in the pathway, preventing overproduction.
- Hormonal regulation: Hormones such as insulin and glucagon regulate metabolism by activating or inhibiting specific enzymes.
