Cellular Respiration Meaning In Biology

Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism.

Cellular respiration meaning in biology. The respiration occurring at the cellular level wherein the cells produce energy by combining oxygen with food molecules is called cellular respiration. In this process glucose breaks down without the help of oxygen and the by-products produced are alcohol CO2 and energy or ATP. Cellular respiration can be described as the reverse or opposite of photosynthesis.

Both aerobic and anaerobic respiration involve chemical reactions which take place in the cell to produce energy which is needed for active processes. Based on the oxygen demand cellular respiration is divided into- Aerobic respiration and Anaerobic respiration. A series of metabolic processes that take place within a cell in which the biochemical energy is harvested from an organic substance eg.

Refer to the image below for a quick overview of the process taking place during this respiration. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate ATP and then release waste products. Cellular respiration is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate and then release waste products.

Glucose and then stored in energy-carrying biomolecule eg. Autotrophs like plants produce glucose during photosynthesis. Anaerobic respiration is another type of cellular respiration that takes place in the absence of oxygen and produces energy.

Cellular respiration the process by which organisms combine oxygen with foodstuff molecules diverting the chemical energy in these substances into life-sustaining activities and discarding as waste products carbon dioxide and water. ATP for use in energy-requiring activities of the cell. Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP.
