Detailed explanation-1: -(i) during inhalation, ribs move inward and diaphragm is raised. (ii) the gaseous exchange takes place in the alveoli. (iii) haemoglobin has greater affinity for carbon dioxide than oxygen. (iv) alveoli increase surface area for the exchange of gases.
Detailed explanation-2: -Aerobic respiration is a series of enzyme-controlled reactions that release the energy stored up in carbohydrates and lipids during photosynthesis and make it available to living organisms. There are four stages: glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation.
Detailed explanation-3: -Expert-Verified Answer. The statement which is true about energy released during cellular respiration is It is used to fuel all other activities in the cell. What is ATP? ATP is the energy driving molecule for all cells to function.
Detailed explanation-4: -Respiration is an energy releasing and enzymatically controlled catabolic process which involves a step-wise oxidative breakdown of organic substances inside living cells.
