LIFE SCIENCE

Detailed explanation-1: -CO2 is released during respiration and forms the product of respiration. Whereas in photosynthesis, the carbon dioxide molecule is fixed to form glucose.

Detailed explanation-2: -They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

Detailed explanation-3: -It leads to the formation of carbon dioxide, water, and energy. When the food is broken down in the absence of oxygen, it is known as anaerobic respiration. It leads to the formation of alcohol, carbon dioxide, and energy. Hence, the end products of respiration are alcohol, carbon dioxide, water and energy.
