The phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase.
B - They both use protein channels (I think so at least) they differ because active transports use a pump to leave the cell and it uses atp (cell energy).
Carbon is both a waste product and an energy source in cellular respiration occurring with glucose molecules and forms the base element in the cellular respiratory cycles of glycolysis and the subsequent Kreb's cycle in which glucose is transformed into energy.
