Study Notes
Chemistry Concepts for Anatomy and Physiology
- Elements: Four primary elements forming the bulk of body matter are listed
- Atoms: Atoms are the basic unit of matter; subatomic particles (protons, neutrons, electrons) compose atoms. Relative masses and charges, along with atomic positions, are described.
- Atomic Structure: Atomic number, atomic weight, atomic mass, isotopes, and radioisotopes are defined
- Compounds vs. Mixtures: The difference between compounds and mixtures is explained; the concept of a molecule is defined.
- Solutions, Colloids, Suspensions: These are types of mixtures, and their differences are outlined
- Chemical Bonding: Electrons' role in chemical bonding and the octet rule are explained. Types of chemical bonds (ionic, covalent, hydrogen) are contrasted and compared.
- Chemical Reactions: Synthesis, decomposition, and exchange reactions are compared. Irreversible reactions and reaction rate factors are explained.
- Importance of Water and Salts: The significance of water and salts in homeostasis is emphasized. The definition and concept of pH is provided.
- Biological Molecules: Carbohydrates, lipids, proteins, and nucleic acids' structures, functions, building blocks, and relationships to dehydration synthesis and hydrolysis are detailed.
- Proteins: Fibrous and globular proteins' building blocks and contrasts are described.
- Enzymes: Enzyme structure, general mechanism of activity, and control mechanisms are explained.
- Nucleic Acids: DNA and RNA are compared, and their structure is explained.
- ATP: The role of adenosine triphosphate (ATP) in cell metabolism is described.
