Detailed explanation-1: -Inside the cell, the food, present in the form of glucose, is broken down into carbon dioxide and water with the help of oxygen. The process of breakdown of glucose to release energy, which can be utilized by our body to perform daily chores like walking, sitting or even thinking, is known as respiration.

Detailed explanation-2: -Once glucose is digested and transported to your cells, a process called cellular respiration releases the stored energy and converts it to energy that your cells can use. Cellular respiration consists of three metabolic processes: glycolysis, the Krebs cycle, and oxidative phosphorylation.

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. There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.

Detailed explanation-4: -ATP. Specifically, during cellular respiration, the energy stored in glucose is transferred to ATP (Figure below). ATP, or adenosine triphosphate, is chemical energy the cell can use. It is the molecule that provides energy for your cells to perform work, such as moving your muscles as you walk down the street.

Detailed explanation-5: -During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
