A Diabetic,who Does Not Utilize Insulin Properly,will Metabolize Fats Instead

A diabetic,who does not utilize insulin properly,will metabolize fats instead of glucose.A condition called diabetic ketoacidosis is a common result of excessive fat metabolism,causing blood pH values of 7.1 or less (normal range = 7.35-7.45) .What has happened to the blood pH and why?

A) The pH is below normal (acidic) because the buffering capacity was exceeded.
B) The pH is above normal (basic) because the ketones are too basic.
C) The pH is not affected because the blood buffers can absorb the excess H+.
D) The pH is below normal because buffers can donate OH+.
