Document Summary
Carbohydrates: carbon, hydrogen, and oxygen cn(h2o)n, provide cells with energy through chemical reactions, role in cell-cell communication, 1% of bw. Proteins: composed of carbon, hydrogen, nitrogen, and oxygen, 17% of bw. Important role in: structure and function of enzymes, transporters, certain hormones, amino acids are building blocks of proteins. Amino acids: amino acids are connected by peptide bonds to form polypeptide chains, protein synthesis, transcription, translation, posttranslational modification. Nucleic acids: deoxyribonucleic acid, ribonucleic acid, 2% of bw, storage, expression and transmission of genetic information. Membrane proteins: hydrophobic regions in the pm, facilitate the movement of ions across pm. Cell structure and function: cytoplasm, semifluid part between cell membrane and nuclear membrane, cytosol, clear fluid portion of the cytoplasm, nucleus. In most cells: double membrane, contains, chromatin, nucleolus; site of rrna production. Endoplasmic reticulum: smooth er, steroid hormone production and inactivation, site for ca storage in muscles, rough er, ribosomes site for protein synthesis and excretion.
