Detailed explanation-1: -Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Detailed explanation-2: -As you can see, cellular respiration begins with one molecule of glucose and some oxygen (the oxygen is in the air that we breathe and is required for cellular respiration), and the end product is energy, with carbon dioxide and water as byproducts.

Detailed explanation-3: -The first product made during cellular respiration is a gas called carbon dioxide. This gas is released from the body when we breathe out.

Detailed explanation-4: -The process of breakdown of food in the cell with the release of energy is called cellular respiration. Cellular respiration takes place in the cells of all organisms. In the cell, the food (glucose) is broken down into carbon dioxide and water using oxygen.

Detailed explanation-5: -Answer and Explanation: The oxygen that is used in cellular respiration primarily comes from the atmosphere. In cellular respiration, oxygen is used as the terminal electron acceptor of the mitochondrial electron transport chain.
