ECM is the extracellular matrix, or the set of extracellular molecules secreted by cells with the purpose to support surrounding cells. In plants the cell wall is the ECM and in mammals ECM can be in the form of fibrils and may constitute a significant portion of the bulk of the organism and it also referred as connective tissue.
Carbon atoms can form 4 covalent bonds.
So it's going to be obviously oxygen XD ....so that's one
Next, it's going to be carbon dioxide, since it has to exit the cell, because it is a waste product ...so that's two
