Cells need to bring in molecules to carry out cellular processes. Often, this requires molecules moving across the cell membrane with the concentration gradient. How do these molecules get into the cell?

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you

This is the most closely resembles the model.
