Why is ATP needed to provide energy for cells?
What will be an ideal response?
ATP is the energy source cells use to fuel metabolic reactions. Cells only have 3—5 seconds' worth of ATP; thus, ATP must be regenerated from ADP and phosphate (which can be donated by creatine phosphate) or produced during anaerobic metabolism, which can fuel the
body for no more than 1.5 minutes, or aerobic metabolism, which can continue indefinitely.
