Question

Some desert beetles can survive on " metabolic water", without drinking water which is

• A. Produced as water in the organisms they eat
• B. Absorbed from air along with respiratory oxygen
• C. Breakdown product of pyruvate inside the mitochondria, along with carbon dioxide
• D. Breakdown product from glycolysis in the cytoplasm

Answer 1

The correct option is C Breakdown product of pyruvate inside the mitochondria, along with carbon dioxide

• Metabolic water is created by oxidizing the energy-containing substances in their food during metabolic activity.
• Some organisms, especially xerocoles, animals living in the desert, rely exclusively on metabolic water.
• They absorb this metabolic water from the air along with the respiratory oxygen.

Thus, the correct answer is option C.
