The K value in the equation for the oxygen binding curve of myoglobin represents the oxygen partial pressure at which half of the oxygen binding sites are occupied, indicating the affinity of myoglobin for oxygen. If Y > K, it means that more than 50% of the myoglobin is saturated with oxygen, not less, making statement D incorrect.
