Desc: |
A series of processes that forms an integrated mechanism by which a cell or an organism detects the depletion of primary sugar sources, usually glucose, and then activates genes to scavenge the last traces of the primary sugar source and to transport and metabolize alternate sugar sources. The utilization process begins when the cell or organism detects sugar levels, includes the activation of genes whose products detect, transport or metabolize sugars, and ends when the sugar is incorporated into the cell or organism's metabolism. |
