If energy is needed to remove a phosphate group from a chain in atp, you can conclude that the energy needed for production must be found outside the cell to maintain balance within proportional to the amount of food taken in by the cell equal to the amount of energy produced less than the amount of energy produced

Pls me i need this ! each cell has genes activated depending on it's job and what kind of cell it is. it is the presence of that causes the repressor protein to fall off and unblock the gene on the lac operon. if a gene is turned on then it is being an additional circular chromosome found in some bacteria that is used in genetic engineering.
