the process by which sugars and starches are slowly oxidized in plants to release energy

The process within plants where sugars and starches are converted into energy.

the conveyance of oxygen to cells and tissues as carbon dioxide and water are given off. In cells, the conversion of food (e.g., glucose) into energy. In most organisms, respiration releases the energy that drives metabolism.

In this process, plants absorb oxygen from the air to turn the sugars formed during photosynthesis into energy for growth, carbon dioxide being given off as a waste product.

biology - the process by which an organism obtains oxygen needed to process food into energy

the process or processes that cells use to generate energy (usually as ATP) from the oxidation of foodstuffs. May be aerobic (using oxygen) or anaerobic (in the absence of oxygen).

Respiration (or just breathing) is defined as the transport of oxygen from the outside air to the cells within tissues, and the transport of carbon dioxide in the opposite direction.

The chemical process of releasing energy from organic compounds. It is a series of enzyme-controlled reactions in which energy is transferred to produce ATP from ADP and inorganic phosphate (Pi).

process by which living things take in oxygen and use it to produce energy. respiratory system

A chemical process in which organisms make energy available for their life processes. One form of respiration (aerobic respiration) combines food and oxygen and gives off carbon dioxide and water.

Respiration is a chemical reaction that takes place in all living cells. It is not the same as breathing or ventilation. When oxygen is conveyed to our tissues and cells, the oxidation products of carbon dioxide and water are given off. In the process, energy released from glucose and provided to our cells to keep them functioning.

The act of breathing (19thc)

A biochemical process by which living organisms take up oxygen from the environment and consume organic matter, releasing both carbon dioxide and heat. In plants, the organic matter in photosynthate produced during daylight hours.

General term for any cellular process involving the uptake of O2 coupled to production of CO2.

The release into the atmosphere of carbon dioxide formed in a plant or animal where ener is released from stored foods: in plants the reverse of photosynthesis.

The process in which an organism uses oxygen for its life processes and gives off carbon dioxide.

A process by which organic matter is converted to energy, carbon dioxide, water, and other things by organisms such as plants, animals, and bacteria.
