What is the function of proteins and carbohydrates that are embedded in a cell membrane? 1.they control what enters and leaves the cell. 2.they direct the reproduction process for the cell. 3.they act as storage molecules for water.

Answer : The correct answer is -

1.They help control what enters and leaves the cell.

Some molecules can not cross the lipid bilayer membrane (cell membrane) of cells (such as large polar molecules and hydrophilic molecules).

There are special carbohydrate and protein that are embedded in the membrane and act like Transmembrane channels or transporters, which assist in the trasport of such molecules (like amino acids and proteins) on both sides across the cell.

Thus, option 1) is the right answer.

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c
