Electron capture rates in the core of a collapsing star are calculated. It is shown that allowed Gamow-Teller transitions are quickly suppressed and that the neutronization rates are dominated by first forbidden transitions. These rates are evaluated using a simple model of the nucleus. In the calculation of the total neutronization rates, the contribution of free protons is also included. Comparison shows that early investigators overestimated the rates by a factor of ~20.
