A pancreatectomy can be performed as a treatment for pancreatic cancer, pancreatic tumors (pre-malignant), chronic pancreatitis, or when the pancreas has been severely damaged by injury. Removing part of or the entire pancreas may cause a loss of pancreatic digestive enzyme production, leading to EPI.
Question: When a nerve fiber is polarized, the concentration... When a nerve fiber is polarized, the concentrationof: A. sodium and potassiumions is higher on the inside of its membrane. B. sodium ions is higher on the inside of its membrane and potassium ions are higher on the outside.
When a nerve impulse is triggered, sodium and potassium pass through the cell membrane along the concentration gradient. To return the concentration gradient to its initial state, the membrane protein must continually pump sodium out of the cell and bring potassium into the cell. This requires energy from the cell.ransport that is âactiveâ is different in that it requires the energy of certain membrane proteins to get across the concentration gradient and either into or out of the cell.
