What are the cathode and anode in a fuel cell made from?
The cathode in a fuel cell is typically made from a material like platinum, which serves as a catalyst for the oxygen reduction reaction. The anode is usually made from a material like nickel, which helps facilitate the oxidation of the fuel.
What term describes the difference in the concentrations of a substance across a cell's membrane?
The term that describes the difference in concentrations of a substance across a cell's membrane is called the concentration gradient. This gradient drives the movement of substances such as ions or molecules across the membrane through processes like diffusion or active transport to achieve equilibrium.
The statement below refers to a structure of the sale oxygen diffuses to destruction by a sodium ion me need to active transport what structure in the statement most likely referred to?
The structure most likely referred to in the statement is the cell membrane. Active transport mechanisms in cells, like the sodium-potassium pump, are responsible for transporting ions such as sodium against their concentration gradient to maintain proper cellular function. Oxygen diffusing into the cell would typically occur through passive transport mechanisms like simple diffusion across the cell membrane.
