Answer:
In a cell, nutrients and proteins are distributed to all parts of the cytoplasm through cytoplasmic streaming, carried out (it has been suggested) by motor proteins.
Step-by-step explanation:
In a cell, the cytoplasm consists of all the parts (organelles, enzymes, nutrients, salts, etc) that are located outside of the nucleus, which are also protected by the cell membrane.
In an eukaryotic cell, the cytoplasm is composed of three parts: cytosol, organelles, and cytoplasmic inclusions. The last ones include proteins (including enzymes), glycogen, lipids, and acids.
Cytoplasmic streaming refers to the movement of cytoplasm within the cell that allows molecules (nutrients and oxygen) to reach all parts of a cell which, as mentioned above, it has been suggested to be carried out with the help of motor proteins that, powered by ATP, can move all nutrients and molecules across the cytoplasm.
