According to a different definition of equilibrium, "every part of a rigid body must be in balance" for the body to be in equilibrium. e-active transport. If carrier proteins can not 'pump' molecules from a lower concentration to a higher concentration, and carrier proteins are slower than channel proteins at transporting molecules, what is the purpose of the carrier protein? 1 Some of these transport mechanisms require the input of energy and use of a transmembrane The specific location within an enzyme molecule where the substrate binds is called the active site. ANSWER: Hint 3. In cells, some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion.

The sodium-potassium pump maintains a state in which the concentration of sodium is low inside the cell relative to the outside and the concentration of potassium is high inside the cell relative to the outside; thus, three sodium ions are pumped out of the cell and two potassium ions are pumped into the cell against the electrochemical gradient. The shape change only occurs due to the binding of the carrier protein's target molecule, in accordance with a concentration gradient. What will happen when the balloon is submerged in the beaker?
