Calculate the standard potential of the cell consisting of the Zn/Zn21 half-cell and the SHE. What will the emf of the cell be if [Zn21] 5 0.45 M, PH2 5 2.0 atm, and [H1] 5 1.8 M?
12/5/16 Physical and Chemical Processes, and the Cellular Environment Factors that influence a cell’s: metabolsim, behavior, etc. All living things consist of 1 or more cells A cell/organism may be considered a system. o “Such wholes that have emergent properties from interactions of the parts we call systems.” - H.T. Odum Life Emerges at the System of the Cell Systems: depending on how/if they interact with their surroundings. o Open: water flows into the system, and flows out. Because this system has inflows and outflows it is an open system. Exchanges materials or energy with their surroundings. o Closed: system has no inflows or outflows. In nature, closed systems are rare and temporary. All processes are occurring within boundaries o Cells interact and exchange materials with their environment. o Earth may appear as a closed system in photos, however earth is an open system because energy flows into the system, from the sun. Are cells open systems Yes Cells take in materials (oxygen, carbon dioxide, light, water, etc.) and materials leave the cell (proteins, hormones, waste products, etc.) Physiological and Chemical processes/ characteristics o Diffusion: Movement of a subs
