Document Summary
Form most of structural aspects of cell + body: structural protein form cytoskeleton, collagen. Protein is broken apart by enzymes (regulators of biological activity, makes things happen quicker) to be absorbed by the body. Transport proteins: facilitates movement of things like sugar to cells. Neurotransmitter, hormone, drugs all connect to receptors. Antibodies: made up of 4 diff chains. Tertiary structure: most functional properties of proteins occur, will interact w/ hormones, neurotransmitters, drugs, surface confirmation that occurs in this structure that gives proteins their purpose. Structures: different levels, levels affect what the proteins do. Nucleus inside of a nuclear envelope: 46 chromosomes, 60,000 genes. Transcription: helicase (enzyme) reads dna and produces mrna with a complimentary strand of letters (atcg, can leave nucleus to go to cytoplasm. Translation: nucleic acid is translated to a protein, associates the chain of letters (amino acids) with a certain protein. Dna -> transcription -> rna -> translation -> protein.
