Document Summary
Physiology: physiology is the science of how the body functions, mechanical, physical, and biochemical properties of living organisms, functionality of the processes of life, inter-relationship of form and function, anatomy is the what , physiology is the how . Physiology is integrative across levels of biological organization. Molecules to chemicals: basic structure of which all substances are composed, atoms, molecules, and macromolecules. Perform functions within the cell and form organelles. Four major classes of macromolecules: proteins, lipids, carbohydrates, nucleic acids. Nucleic acids: dna, rna, functions, genes that code for proteins, sites that regulate gene expression. Proteins: most abundant macromolecule in the body, created by translating dna into amino acids which are assembled into polypeptides, one or more polypeptides come together to form proteins, functions, many diverse functions! The structure and function of proteins is determined by a combination of chemical and physical forces.
