Why do cancer cells use glutamine?

One reason that cancer cells rely on high levels of exogenous glutamine is because glutamine can be used to fuel the TCA cycle through α-ketoglutarate to allow its further oxidation [13]. It was shown that glutamine depletion reduces the NADH/NAD+ ratio, which inhibits oxygen consumption and ATP production [14].
