Answer:

The correct answer is integral membrane proteins.

Explanation:

The plasma membrane is the outer membrane of the cell which is selectively permeable. The small polar molecules and hydrophobic molecules can go through the lipid bilayer, but ions and large polar molecules cannot go through. There are some Integral membrane proteins present in the plasma membrane that enable ions to pass through the plasma membrane by active or passive transport.

Thus, the correct answer is integral membrane proteins. Ions generate electrochemical gradient so they are generally used in secondary transport systems.

Thus, the correct answer is integral membrane proteins.

If a double foul occurs during a down in which time expires, the period is ended
Zina [86]
This statement is false.

Double fouls are when two players on opposing teams commit a foul, which makes the fouls of the players "cancel out" and ball possession does not change. However, personal fouls are still charged on both of the offending players.
