A runner is brought to the emergency room after vomiting on

A runner is brought to the emergency room after vomiting on the side of the road during a high intensity run. Laboratory tests reveal that the patient has low blood pH. The most likely reason for the low blood pH is: Insufficient oxygen intake leading to gluconeogenesis Insufficient glucose intake leading to fermentation Insufficient oxygen intake leading to fermentation Insufficient glucose intake leading to gluconeogenesis

Solution

Answer is Insufficient glucose intake leading to gluconeogenesis.

When glucose levels are depleted, the muscle starts to utilise reserve fats to produce glucose. This produces acidic byproducts which reduce the blood pH
