Biological and Biochemical Foundations of Living Systems

Foundational Concepts

  • Processes unique to living organisms include growth, reproduction, homeostasis, energy acquisition, sensitivity to environmental changes, and adaptation.

Foundational Concept 1: Biomolecules

  1. Proteins and Amino Acids

    • Proteins composed of amino acids, with unique structures determining their function.

    • Amino Acid Structure: Contains amino group, carboxyl group, hydrogen, and a distinctive R group (side chain).

    • Stereochemistry: All amino acids in proteins are L-amino acids except for cysteine (which is R).

    • Classifications:

      • Acidic: Aspartic acid, Glutamic acid.

      • Basic: Histidine, Lysine, Arginine.

  2. Protein Structure:

    • Primary Structure: Sequence of amino acids.

    • Secondary Structure: α-helix and β-sheets held together by hydrogen bonds.

    • Tertiary Structure: 3D shape due to interactions among side chains (R groups).

    • Quaternary Structure: Assembly of multiple polypeptide chains.

  3. Chemical Reactions and Bonding

    • Peptide bonds between amino acids, disulfide bonds in cysteine.

    • Hydrolysis and dehydration reactions.

Cellular Mechanism and Energy Changes

  • Metabolism involves endothermic and exothermic reactions, ATP as primary energy currency.

  • Glycolysis and cellular respiration for energy extraction from nutrients.

Enzyme Functionality

  • Enzymes as catalysts, enhancing reaction rates without being consumed. Different types of inhibitors and their effects on enzyme activity.

Genetics and Molecular Biology

  • Nucleic Acids: DNA and RNA structures, processes of transcription and translation, and the concept of the central dogma.

  • Gene Regulation: Operon model in prokaryotes, transcription factors in eukaryotes.

Additional Concepts

Ecology and Evolutionary Biology

  • Understand natural selection and ecological interactions.

  • Concepts of speciation and evolutionary mechanisms.

Anatomy and Physiology
