Substances cross the cell membrane without the cell expending energy
Homeostasis refers to the necessity of an organism to maintain constant or stable conditions. In order to maintain homeostasis, all organisms have processes.
Cellular Transport Figure 6-12 Both diffusion and facilitated diffusion are forms of passive transport, as neither process requires the cell to expend.
Passive Transport. Healthy Cell 70% water 15% protein 10% fat 4% DNA and other materials 1% carbohydrate.
