Cellular Respiration Meaning In Biology

In this process glucose is broken down in the presence of molecular oxygen into six molecules of carbon dioxide and much of the energy released is preserved by turning ADP and free phosphate into ATP.

Cellular respiration meaning in biology. During cellular respiration glucose in the presence of oxygen is converted into carbon dioxide and water. Cellular respiration is a biological process in which cells convert sugar amino acids and fatty acids into energy utilized by the cell. Autotrophs like plants produce glucose during photosynthesis.

The process takes place in the cytoplasm of a cell. Cellular respiration Energy from nutrients is converted into ATP. A series of metabolic processes that take place within a cell in which the biochemical energy is harvested from an organic substance eg.

Related Biology Terms. In contrast to simple combustion cellular respiration involves the step-wise release of energy in a tightly regulated fashion. The process plays an essential role in maintaining the biological functions of all living cells.

Based on the oxygen demand cellular respiration is divided into- Aerobic respiration and Anaerobic respiration. Cellular respiration Cellular respiration n. Cellular respiration is a set of metabolic reactions occurring inside the cells to convert biochemical energy obtained from the food into a chemical compound called adenosine triphosphate ATP.

Anaerobic respiration is another type of cellular respiration that takes place in the absence of oxygen and produces energy. ATP for use in energy-requiring activities of the cell. Some organisms such as plants can trap the energy in sunlight through photosynthesis see Chapter 5 and store it in the chemical bonds of carbohydrate molecules.

Cellular respiration refers to both aerobic and anaerobic respiration but is often synonymous with aerobic respiration. Cellular respiration can be described as the reverse or opposite of photosynthesis. The cellular context In the diagram at left 1 represents the cell exterior.
