To determine the number of moles of ATP available for cellular use if 3 moles of NADH and 4 moles of FADH 2 are oxidized within a mitochondrion. Concept introduction: Electron transport chain ( ETC ) is a sequence of biochemical reactions in which electrons and hydrogen atoms from the citric acid cycle are transferred to various intermediate carriers and finally reacts with molecular oxygen to form a water molecule. The reaction of the formation of the water is: O 2 + 4 e − + 4 H + → 2 H 2 O FADH 2 is the reduced form of flavin adenine dinucleotide. The main function of flavin adenine dinucleotide is to act as an oxidizing agent and used by the cell in oxidation reactions like oxidation of fatty acid. NADH is the reduced form of nicotinamide adenine dinucleotide. It is employed as an oxidizing agent in various reactions like oxidation of secondary alcohol into a ketone . Its structure consists of three subunits: nicotinamide, ribose, and ADP.

Question

The average adult consumes approximately 11,700 kJ per day. Assuming that the metabolic pathways leading to ATP synthesis operate at 50% thermodynamic efficiency, about 5850 kJ ends up in the form of synthesized ATP.

Interpretation Introduction

Interpretation: To determine the number of moles of ATP available for cellular use if 3 moles of NADH and 4 moles of FADH₂ are oxidized within a mitochondrion.

Concept introduction: Electron transport chain (ETC) is a sequence of biochemical reactions in which electrons and hydrogen atoms from the citric acid cycle are transferred to various intermediate carriers and finally reacts with molecular oxygen to form a water molecule. The reaction of the formation of the water is:

O2+4e−+4H+→2H2O

FADH₂ is the reduced form of flavin adenine dinucleotide. The main function of flavin adenine dinucleotide is to act as an oxidizing agent and used by the cell in oxidation reactions like oxidation of fatty acid.

NADH is the reduced form of nicotinamide adenine dinucleotide. It is employed as an oxidizing agent in various reactions like oxidation of secondary alcohol into a ketone. Its structure consists of three subunits: nicotinamide, ribose, and ADP.
