Document Summary
Cells use atp, which is the major energy source of the cell. Glucose and oxygen is used in a number of steps to give rise to atp. Dna replication is high-fidelity (giving rise to something similar to original) to have perfect copies which requires a lot of energy. Separation of dna for replication also requires energy as copies are separated to cells during mitosis. Protein production requires energy as the cell need proteins in order for proper function. This tells other cells what proteins to make. Biochemical factors (proteins) all work together in the cell to produce an effect. All cells will utilize the same subset of molecules to derive all of their needs and carry out specific programmed functions. Rotary protein on membrane that hydrolyzes atp and it pumps h+ ions out of the cell. Many subunits of the protein complex work together to make it functional. This pump is found in lysosomes, stomach and etc.
