Which of the following steps during glycolysis is associated with util...

In the initial phase (energy spendling phase) of glycolysis, the hexoses (i.e., glucose and fructose) ar phosphorylated in a reaction that uses ATP at two steps : First in the conversion of glucose into glucose-6-phosphate and second in the conversion of fructose-6-phophaste to fructose-1,6-biphosphate.
These reactions are catalysed by the hexokinase and phospho-fructokinase respectively

Which of the following conversions involve ATP synthesis during glycolysis?

View answer

Read the passage given below and answer the following questions:Adenosine triphosphate (ATP) is the energy carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes. ATP is a nucleotide that consists of three main structures: the nitrogenous base, adenine; the sugar, ribose; and a chain of three phosphate groups bound to ribose. The phosphate tail of ATP is the actual power source which the cell taps. Available energy is contained in the bonds between the phosphates and is released when they are broken, which occurs through the addition of a water molecule (a process called hydrolysis). Usually only the outer phosphate is removed from ATP to yield energy; when this occurs ATP is converted to adenosine diphosphate (ADP), the form of the nucleotide having only two phosphates.The importance of ATP (adenosine triphosphat e) as the main source of chemical energy in living matter and its involvement in cellular processes has long been recognized. The primary mechanism whereby higher organisms, including humans, generate ATP is through mitochondrial oxidative phosphorylation. For the majority of organs, the main metabolic fuel is glucose, which in the presence of oxygen undergoes complete combustion to CO2 and H2O: C6H12O6 + 6O2 → 6O2 + 6H2O + energyThe free energy (ΔG) liberated in this exergonic (ΔG is negative) reaction is partially trapped as ATP in two consecutive processes: glycolysis (cytosol) and oxidative phosphorylation (mitochondri
