An enzyme that follows the MWC (also known as the concerted model) model for allostery has a T/R ratio of 300 in the absence of substrate. Suppose that a mutation were to reverse that ratio(T/R= 1/300= 3.3 x 10^-3). How would this mutation affect the relation between the rate of […]

1. A sea urchin egg is used in a voltage clamp experiment; that is, the value of the transmembrane voltage is set by the experimenter, not by the properties of the membrane.The transmembrane voltage is held at +10 mV for one minute. At the end of that timeA. the voltage-gated calcium […]
