Question

During aerobic cellular respiration, _____ combines with hydrogen ions and the product is released as water, a by-product of respiration.

Answer 1

During aerobic cellular respiration, (oxygen) combines with hydrogen ions and water is released as a by-product of respiration.

Answer 2

Answer: Oxygen (O2)

Explanation: Oxygen ions combines with hydrogen ions to form water molecules.

Cellular aerobic respiration occurs in the mitochondria. Aerobic respiration requires oxygen and glucose and releases carbon dioxide, water, and energy as by products.

The chemical equation is; C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (ATP).

(glucose + oxygen -> carbon dioxide + water + energy).
