The binding of sodium ions (NA+) to a membrane protein is one of the first steps in initiation of the sodium-potassium pump that moves these ions across the membrane. The picture shows the initial step of this process. How does the protein get the energy needed to continue the process of moving NA+ across the cell membrane?

a)

Mitochondria will attach to the protein and provide the energy to push the NA+ through the proteins.

b)

Energy from ADP is released and a channel in the membrane protein permanently opens, resulting in the passage of the NA+

c)

Energy produced from the difference in solute concentration on both sides of the membrane pulls the NA+ through the protein

d)

ATP attaches to the protein and releases a phosphate, making energy available to change the shape of the protein and allowing the passage of the NA+

130.

How is energy made available to the cell to move large starch molecules across the membrane through the process of endocytosis?

a)

Removing a phosphate from ATP

b)

Combining two glucose molecules

c)

Breaking carbon bonds in fatty acids

d)

Splitting the oxygen and hydrogen in a water molecule

131.

A freshwater plant is placed in a container of saltwater. What will most likely happen to the cells of the plant?

a)

They will swell because water will move into them

b)

They will swell because salt will move into them

c)

They will shrink because water will move out of them

d)

The will shrink because salt will move out of them

132.

If energy is needed to move materials into or out of a cell, what is most likely occurring?
