Aquaporins are proteins that control the passage of water molecules across a cell membrane. The protein forms a pore, or opening
timofeeve [1]

The two different molecules of aquaporin will have different sequences of amino acids

Explanation:

Aquaporins are an integral type of membrane proteins. They act as water channels and their function is to transport water and other solute materials across cells membranes and thereby control and regulate the water content of the cells.

They are formed by clustering of four water channel monomers forming a tetramer.

Each aquaporin is made up of a specific linear sequence of amino acids and variations in the sequence leads to formation of different aquaporins.

There are more than 10 types of aquaporins are known. The sizes of the aquaporins differ according to their pore diameter of each type and this difference leads to the selective permeability of water across cell membranes.

Plant cells contain both chloroplasts and mitochondria; animal cells have only mitochondria. What can be inferred from this stat
Svetlanka [38]

Answer: D. Plants do not eat, so both chloroplasts and mitochondria are needed to make enough energy for plants to grow.  

Explanation: Option A is invalid since plant cells do use ATP. Option B is invalid since animal cells don't make their energy with chloroplasts. Option D is the most realistic one since chloroplasts in the plant are the ones that make the food for the plants, plant doesn't have a "mouth" so they depend on chloroplast to make food.

Describe the function of sodium and potassium in the generation of an action<br> potential.
larisa [96]

Answer:

The inward flow of sodium ions increases the concentration of positively charged cations in the cell and causes depolarization, where the potential of the cell is higher than the cell's resting potential. The sodium channels close at the peak of the action potential, while potassium continues to leave the cell.
