Question

1. The terms “equilibrium” and “homeostasis” refer to different things. Equilibrium plays an important role in the human body. Which of the following processes are likely to depend upon a system trying to reach equilibrium?

   1. The maintenance of high levels of sodium outside the cell and low levels inside the cell (this is our “resting” state)

   2. Allowing sodium to cross the cell membrane so that sodium concentration inside the cell attempts to equal the sodium concentration outside the cell (this is the electrical signal that causes muscles to contract)

   3. The maintenance of high levels of ATP within cells

   4. Water crossing cell membranes so that the water concentration outside a cell equals the water concentration inside the cell.

   5. The maintenance of blood pressure

Answer 1

Equilibrium plays an important role in the human body the following processes are likely to depend upon system try to reach equilibrium are

1)Allowing sodium to cross the cell membrane so that sodium concentration inside the cell attempts to equal the sodium concentration outside the cell

2)Water crossing cell membrane so that water concentration outside cell equals the water concentration inside the cell
