Detailed explanation-1: -Photosynthesis transforms light energy into chemical energy stored in glucose, and cellular respiration releases the energy from glucose to build ATP, which does the work of life.
Detailed explanation-2: -The lungs and respiratory system allow us to breathe. 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: -Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body.
Detailed explanation-4: -Respiration is essential for survival of living organisms. It releases energy from the food. The oxygen we inhale is used to breakdown glucose into carbon dioxide and water. Energy is released in the process.
Detailed explanation-5: -Respiration is the process through which living organisms take in oxygen and give out carbon dioxide to release energy. During respiration, there is a release of carbon-dioxide and water when glucose is broken down in the presence of oxygen. During this reaction, the energy is released.
