How does nutrients travel though a cell?

How does a cell eat, and how does that food travel through it? Like first the food goes through the membrane, then it gets sent to the E.R, then that sends it to whatever, and that thing will do this, etc. Thanks!How does nutrients travel though a cell?Okay, so the food is already digested and it diffuses through the membrane. Then the glucose molecules are put through cell respiration to provide ATP for the cell and power its functions. The amino acids are the base units to build together proteins. The nucleic acids are the base units to build up DNA and RNA. And the lipids are used in steroid hormones as well as the cell membrane and put in fat cells.



So it really depends on what food you're talking about!How does nutrients travel though a cell?A cell can "eat", or ingest nutrients through a variety of ways. As far as eating there is phagocytosis (literally means cell eating) and pinocytosis (cell drinking) as a way to ingest nutrients in membrane bound vacuoles. In this case, molecules are generally taken to the ER but what happens then depends on the cell and the ingested molecules.



Other way for extracellular nutrients to get through the cell membrane for use by the cell are: active transport, passive transport, ion channels and osmosis.
