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 meaning in biology. 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 occurring inside the cells to convert biochemical energy obtained from the food into a chemical compound called adenosine triphosphate ATP. Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism.

Cellular respiration is a process that all living things use to convert glucose into energy. The stages of cellular respiration include glycolysis pyruvate oxidation the citric acid or Krebs cycle and oxidative phosphorylation. Cellular respiration can be described as the reverse or opposite of photosynthesis.

In this process glucose breaks down without the help of oxygen and the by-products produced are alcohol CO2 and energy or ATP. Other types of organisms such as animals fungi many protozoa and a large. In the cells of any non-photosynthetic eukaryote such as a person bread mold or a paramecium glucose and oxygen are going to come from outside the cell.

Cellular respiration is the process through which cells convert sugars into energy. Organisms that do not depend on oxygen degrade foodstuffs in a process called fermentation. During cellular respiration glucose in the presence of oxygen is converted into carbon dioxide and water.

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. 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. 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.

The process of cell catabolism in which cells turn food into usable energy in the form of ATP. Google Classroom Facebook Twitter. Cellular respiration Cellular respiration n.
