Cells release Carbon Dioxide. This is due to respiration.
Hemoglobin, a protein in red blood cells, dissociates from oxygen to release oxygen to tissues in the body. This process occurs in the lungs where oxygen is picked up and then released in areas where it is needed.
cells use the oxygen to release chemical energy.

oxygen
As red blood cells travel through capillaries oxygen is released (disassociated) with hemoglobin. The oxygen then diffuses down it's concentration gradient into the tissues.
Oxygen is released as a byproduct during photosynthesis when cells take in carbon dioxide. This oxygen is crucial for supporting respiration in living organisms.

At tissue cells, the dissociation reaction primarily involves the release of oxygen from hemoglobin in red blood cells. This process occurs as oxygen binds reversibly to hemoglobin in the lungs and is then released in tissues where the oxygen concentration is lower and carbon dioxide concentration is higher. The presence of carbon dioxide and protons (H+) in tissues shifts the hemoglobin-oxygen binding curve, promoting oxygen release to meet the metabolic needs of the cells. This is known as the Bohr effect, facilitating efficient oxygen delivery where it is most needed.
With the Bohr effect, more oxygen is released in tissues that are actively metabolizing due to a decrease in pH. This decrease in pH reduces the affinity of hemoglobin for oxygen, allowing it to release more oxygen to the metabolizing cells.
energy, water and oxygen
As overall it does not. Only glucose and oxygen is released.
Plants release oxygen through a process called photosynthesis, which occurs in the chloroplasts of plant cells. During photosynthesis, plants combine carbon dioxide from the air with water to produce glucose (food) and release oxygen as a byproduct.
