Detailed explanation-1: -Carbon dioxide, made by the cells as they do their work, moves out of the cells into the capillaries, where most of it dissolves in the plasma of the blood.
Detailed explanation-2: -During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates.
Detailed explanation-3: -During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
Detailed explanation-4: -As cells do their work, they make carbon dioxide. The carbon dioxide moves out of the cells into the capillaries and bloodstream. Blood rich in carbon dioxide travels to the heart, which pumps it to the lungs. Carbon dioxide goes from the capillaries around the alveoli into the alveoli.
