    Study Notes

    Cancer

    • Cancer is a cellular disorder caused by the body's inability to control cell division.
    • Different types of cancer affect different parts of the body: melanoma (skin), leukemia (bone marrow white blood cells), carcinoma (internal organs or skin lining), sarcoma (bone or connective tissue), and lymphoma (immune system cells).
    • Cancer begins when a group of cells ignore their genetic programming, lose their specialization, and divide uncontrollably.
    • Cancer can impact the functioning of the body's organ systems.

    Physiology

    • Physiology is the normal function of cells, organs, or organ systems.

    Nervous System

    • The nervous system coordinates and regulates the functions of other body systems, responding rapidly to both internal and external stimuli.

    Endocrine System

    • Endocrine glands produce hormones that regulate and coordinate different systems, working more slowly than the nervous system.

    Respiratory System

    • This system provides tissues with oxygen and removes carbon dioxide from the blood, as well as regulates the blood's pH.

    Cardiovascular System

    • This system transports nutrients and oxygen to tissues, and removes waste products, along with hormones secreted by the endocrine system.

    Digestive System

    • The digestive system supplies nutrients and water to tissues and removes undigested waste material.

    Urinary System

    • This system eliminates waste products and regulates the water and electrolyte balance of the blood.

    Lymphatic System

    • The lymphatic system maintains blood volume, collects excess fluid, defends against disease.

    Muscular System

    • The muscular system maintains body temperature, supports and protects organs, and facilitates movement.

    Cells

    • Cells are the fundamental units of life, and have the ability to acquire materials and energy, respond to their environment, reproduce, maintain an internal environment, and adapt to changes.
    • Prokaryotic cells are found in bacteria
    • Eukaryotic cells are found in animals, plants, and fungi.

    Organelles

    • Organelles within cells are specialized membrane-bound compartments that carry out specific functions.
    • Organelles allow compartments to specify and regulate chemical reactions.
    • Nucleus - Contains genetic information.
    • Ribosomes - Sites of protein synthesis.
    • Mitochondria - Produce energy.

    Nucleic Acids - DNA

    • DNA is a nucleic acid composed of nucleotides.
    • A nucleotide contains a 5-carbon sugar, a phosphate group, and a nitrogenous base.
    • The nitrogenous bases in DNA are adenine, guanine, cytosine, and thymine.
    • DNA exists as a double helix formed by complementary base-pairing between strands.
    • Genome - the complete set of genetic information in a cell.

    Gene Expression

    • Gene expression is the process where cells use information in DNA to produce proteins.
    • DNA holds instructions for making proteins.
    • Protein production happens outside of the nucleus, in the cytoplasm of cells.

    Transcription

    • Transcription converts DNA information into mRNA.
    • RNA polymerase unwinds DNA and creates a complementary mRNA strand.

    Translation

    • Translation converts mRNA into protein.
    • Ribosomes read the mRNA codons and link amino acids together into chains to create a protein. .

    Protein Structure

    • Protein structure involves the arrangement of amino acids.
    • Primary structure - linear sequence of amino acids.
    • Secondary structure - amino acid interactions (alpha-helices and beta-sheets).
    • Tertiary structure - three-dimensional structure of the folded protein.
    • Quaternary structure - interaction of multiple protein chains.

    Enzymes

    • Enzymes are proteins that catalyze chemical reactions in the body.
