Which of the following statements about the citric acid cycle is false?
A) The process occurs in the mitochondria.

Citric Acid Cycle
A series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats, and proteins into carbon dioxide.
Mitochondria
Cellular organelles often referred to as the powerhouses of the cell, where respiration and energy production occur.
Lactate
A byproduct of anaerobic metabolism in tissues, often associated with strenuous exercise or metabolic dysregulation.

Final Answer :
B
Explanation :
The major end product of the citric acid cycle is not lactate; it is actually carbon dioxide and high-energy molecules like NADH and FADH2. Lactate is a product of anaerobic glycolysis, not the citric acid cycle.
