Cellular Respiration Meaning In Biology

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.

Cellular respiration meaning in biology. Anaerobic respiration is another type of cellular respiration that takes place in the absence of oxygen and produces energy. Cellular respiration stores chemical energy in the form of phosphorylated nucleotides primarily ATP by means of oxidative reactions and makes it available to other reactions. Metabolism refers to a set of chemical reactions carried out for maintaining the living state of the cells in an organism.

Cellular respiration Cellular respiration n. Both aerobic and anaerobic respiration involve chemical reactions which take place in the cell to produce energy which is needed for active processes. The stages of cellular respiration include glycolysis pyruvate oxidation the citric acid or Krebs cycle and oxidative phosphorylation.

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 can be described as the reverse or opposite of photosynthesis. But cellular respiration is slightly more complicated than just converting the energy from glucose into ATP.

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. To create ATP and other forms of energy to power cellular reactions cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form. Cellular respiration is a biological process in which cells convert sugar amino acids and fatty acids into energy utilized by the cell.

The respiration occurring at the cellular level wherein the cells produce energy by combining oxygen with food molecules is called cellular respiration. Signal transduction The transmission of signals from a cells outside to its inside. The principal carbohydrate formed through photosynthesis is glucose.

Other types of organisms such as animals fungi many protozoa and a large. The cellular context In the diagram at left 1 represents the cell exterior. Based on the oxygen demand cellular respiration is divided into- Aerobic respiration and Anaerobic respiration.
