The reason for the need of pentose phosphate pathway by an organism that uses glycolysis and Krebs cycle. Introduction: Glucose is oxidized by many organisms to acquire energy for their metabolic reactions. Glucose is catabolized by either cellular respiration or by fermentation which results into formation of organic waste products. Cellular respiration leads to formation of CO 2 and water as waste products, apart from energy.

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

Why is the formation of fructose-1,6-bisphosphate the committed step in glycolysis?

Why must glucose be “primed” with a high-energy phosphate bond before it can be degraded in the glycolytic pathway?

Which statement best describes the reason why some of the reactions of glycolysis cannot be run in reverse in gluconeogenesis? 1) The last reactions occur in mitochondria and reactions there can never be reversed. 2) Glycolysis includes isomerization reactions and these can never be reversed. 3) There are some allaşteric enzymes and allosteric enzymes can never be reversed. 4) Some reactions have such large negative free energy changes that they can never be reversed under cellular conditions.
