Cellular respiration is the process of oxidizing biological fuels using an inorganic electron acceptor, such as oxygen, to drive production of adenosine triphosphate (ATP), which contains energy. Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical ...
The energy stored in the chemical bonds of glucose is released by the cell in the citric acid cycle, producing carbon dioxide and the energetic electron donors NADH and FADH. Oxidative phosphorylation uses these molecules and O 2 to produce ATP, which is used throughout the cell whenever energy
When animals and fungi consume plants, they use cellular respiration to break down these stored carbohydrates to make energy available to cells. [2] Both animals and plants temporarily store the released energy in the form of high-energy molecules, such as adenosine triphosphate (ATP), for use in various cellular processes.
Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the diffusion and transport of metabolites between the organism and the external environment.
ATP can be produced by a number of distinct cellular processes; the three main pathways in eukaryotes are (1) glycolysis, (2) the citric acid cycle/oxidative phosphorylation, and (3) beta-oxidation. The overall process of oxidizing glucose to carbon dioxide , the combination of pathways 1 and 2, known as cellular respiration , produces about 30 ...
Maintenance respiration, the amount of cellular respiration required for an organism to maintain itself in a constant state; Respiration (physiology), transporting oxygen and carbon dioxide between cells and the external environment Respiratory system, the anatomical system of an organism used for respiration; Breathing, passing air in and out ...
Cellular waste products are formed as a by-product of cellular respiration, a series of processes and reactions that generate energy for the cell, in the form of ATP. One example of cellular respiration creating cellular waste products are aerobic respiration and anaerobic respiration .
The flavoprotein family contains a diverse range of enzymes, including: Adrenodoxin reductase that is involved in steroid hormone synthesis in vertebrate species, and has a ubiquitous distribution in metazoa and prokaryotes [1]
