catabolism

Examples of catabolism in the following topics:

• Catabolic-Anabolic Steady State

  • Catabolic reactions that break complex molecules provide the energy needed by anabolic reactions to produce complex molecules.
  • Anabolism is the opposite of catabolism.
  • Catabolism is a "downhill" process where energy is released as the organism uses up energy.
  • Anabolism and catabolism must be regulated to avoid the two processes occurring simultaneously.
  • Catabolic hormones include adrenaline, cortisol and glucagon.

• Absorptive State

  • When the gastrointestinal tract is full, anabolism exceeds catabolism; this is the absorptive state.
  • Absorptive state is the period in which the gastrointestinal tract is full and the anabolic processes exceed catabolism.

• Mechanisms of Chemical Digestion

  • Digestion is a form of catabolism: a breakdown of large food molecules (i.e., polysaccharides, proteins, fats, nucleic acids) to smaller ones (i.e., monosaccharides, amino acids, fatty acids, nucleotides) .
  • A simplified outline of the catabolism of proteins, carbohydrates and fats

• The Resistance Reaction

  • Resistance is the second stage and increased secretion of glucocorticoids play a major role, intensifying the systemic response—they have lypolytic, catabolic and antianabolic effects: increased glucose, fat and amino acid/protein concentration in blood.

• Anabolic Steroids and Muscles

  • The effect of anabolic steroids on muscle mass is caused in at least two ways: first, they increase the production of proteins; second, they reduce recovery time by blocking the effects of the stress hormone cortisol on muscle tissue, so that catabolism of muscle is greatly reduced.

• Digestion in the Mouth, Pharynx, and Esophagus

  • It is a form of catabolism: a breakdown of large food molecules into smaller ones.

• Acidosis

  • Renal acidosis is associated with an accumulation of urea and creatinine as well as metabolic acid residues of protein catabolism.
