Answer:
Chromatin
Explanation:
The unwound, filamented mass of DNA and associated proteins in a cell that is not dividing id termed as 'chromatin'. The major function of the chromatin is to pack the DNA into the compacted dense shape so that any type of tangling is avoided in the DNA strands. The chromatin is known to be present in every eukaryotic cell. It is due to chromatin that the chromosomes are properly segregated during the anaphase. The nucleus is the site where chromatin is present.
Bulk flow systems move substances faster than simple diffusion.
Answer:
Carrier proteins are known to be glycoproteins, while channel proteins are lipoproteins.
Explanation:
The carrier proteins and channel proteins are both classes of membrane transport protein. The channel proteins are considered as the class of proteins that give the cell membrane in allowing the flow of molecules to and fro along the concentration gradients, while the carrier proteins, only open to a type of membrane at a particular time.
It should be noted also that, the movement or transportation of substances through membrane is done passively by the channel proteins, while transportation of substances is done both passively by secondary active transport or facilitated diffusion by the carrier proteins.
