Item CE138001: Proteins needed for growth and repair of the cell are built by the cell itself.

Proteins are complex molecules needed for the growth and repair of cells. What is TRUE about where these proteins in multicellular organisms come from?

  1. These proteins are built by specialized cells for all other cells in the organism to use.
  2. These proteins are built by each cell for its own use.
  3. These proteins are not built by the cells; instead, they are taken in from the cell’s environment.
  4. These proteins are not built by the cell or taken in from the outside; these proteins are already in the cell.
