Document Summary
Protein synthesis: transcription dna template makes messenger rna (mrna, mrna carries code to ribosome (protein factories , translation mrna specifies sequence of amino acids to transfer rna (trna) Deficit in hemoglobin sequencing glutamic acid of 2 proteins replaced with valine. Changes shape and function of red blood cell cresent-shaped. Symptoms: dehydration, hemolytic anemia (blood vessels burst), fever, joint & abdominal pain. Expressed = cell converts genetic code into rna and protein. Cells can regulate expression to make amounts and types of protein needed. Polyunsaturated fats have a roll in influencing gene expression for lipid enzymes. Growth and maintenance: building blocks for most body structures. Collagen = cell glue (connective tissue: replacement of dead or damaged cells. Enzymes: break down (catabolic), build up (anabolic), & transform substances, catalysts speed up reactions. Hormones: messenger molecules, some are proteins (not all estrogen & testosterone, transported in blood to target tissues.
