Question

Some desert beetles can survive on “metabolic water” without ever drinking liquid water. This metabolic water is

• A. is produced as water in the organisms they eat
• B. is absorbed from the air along with respiratory oxygen
• C. is a breakdown product of pyruvate inside the mitochondria along with $C{O}_2$
• D. is a breakdown product from glycolysis in the cytoplasm

Answer 1

The correct option is C

is a breakdown product of pyruvate inside the mitochondria along with $C{O}_2$

Metabolic water is a break down product of pyruvate inside the mitochondria along with $C{O}_2$, so some desert beetles can survive without ever drinking. Oxidative phosphorylation is release of energy from electrons removed during substrate oxidation by ATP formation.
