How a change in glycoproteins affects a cell’s ability to maintain homeostasis
Licemer1 [7]

Explanation:

Most of the cell surface receptors and glycoproteins. These glycoproteins have active sites that recognize specific signals, like hormones, that initiate secondary signaling pathways inside of the cell, in response to the external signal. This is how cells respond to environmental stimuli.

If a change in glycoproteins makes them unable to bind signaling molecules (like hormones) or makes them permanently bind these molecules, there will definitely be a defect in how the cell responds to external stimuli.  The cell will be, for example, be unable to respond to insulin in case of elevated blood sugar levels as is the case with diabetics.
