Detailed explanation-1: -During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.

Detailed explanation-2: -Answer and Explanation: The stage of cellular respiration in which carbon dioxide release takes place is the citric acid cycle. Aerobic cellular respiration has three steps, glycolysis, the citric acid cycle and the electron transport chain.

Detailed explanation-3: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Detailed explanation-4: -Answer and Explanation: Carbon dioxide is released during B) oxidation of pyruvate to acetyl CoA and the citric acid cycle. during cellular respiration. During pyruvate oxidation, one carbon dioxide molecule is released per pyruvate (2 per glucose molecule).
