The four stages of cellular respiration for oxidation process of glucose and to identify the cellular location where the general process takes place. Concept introduction: Cellular respiration is the process by which cell is able to break the glucose molecule with the help of enzymes which are biocatalysts. These are biomolecules that help in speeding up a chemical reaction by lowering the activation energy. The process of oxidation of glucose is responsible for generation of energy in humans.

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.

In some tissues, glucose 6-phosphate is oxidized to pentose phosphates by the pentose phosphate pathway. a) Which tissues prefer this pathway and why? Explain in detail. b) Due to the fact that glucose 6-phosphate is also an intermediate for the glycolysis pathway, the regulation of glycolysis and pentose phosphate pathway is very important. NADPH plays a crucial role in partitioning of glucose 6-phosphate between glycolysis and the pentose phosphate pathway. Explain this role of NADPH in detail.

Which reactions of glycolysis can be reversed? Which are irreversible? What is the significance of the metabolically irreversible reactions?
