Document Summary

3 main function of active transport in cell and organelles are: uptake of essential nutrients from the fluid surrounding cells even when their concentrations are lower than in the cells, removal of secretory or waste materials from cells or organelles even when the concentration of those materials is higher outside the cells or organelles, maintenance of essentially constant intracellular concentration of h+, na+, k+ and ca2+. Most fundamental of these are the following: cells made of lipid molecules brought together forming a bilayer, a genetic system based on dna, a system of information transfer dna to rna to protein, a system of protein assembly from a pool of amino acids by translation using messenger rna (mrna) and transfer rna (trna) using ribosomes, reliance on proteins as major structural and catalytic molecule, use of atp as the molecule of chemical energy, the breakdown of glucose by the metabolic pathway of glycolysis to generate.
