Question

Total number of atp produced when 1 molecule of g3p participates in aerobic respiration in most of the eukaryotes

Answer 1

32Atp are produced in anaerobic respiration.

Answer 2

Answer:

2 ATP

Explanation:

• Respiration refers to the biological oxidation of organic food molecules i.e. enzymatic breaking of C-C bonds results in the release of energy.

• Aerobic respiration is common to all eukaryotic organisms including plants and animals.

• The general equation for aerobic respiration can be stated as :

                C₆H₁₂O₆   +    6O₂      →      6CO₂    +       6H₂O    +    ATP

• Glycolysis is aerobic respiration which means the splitting of sugar. It represents the set of reactions in which glucose is partially oxidized into two molecules of pyruvates.

• Glycolysis:- Glucose → Glyceraldehyde-3-Phosphate or G3P

• Glycolysis is conveniently considered in two major groups of reactions.

1. The first group of reactions is regarded as the preparatory or investment phase since energy in the form of ATP is consumed during this phase. During this phase, activation of glucose or (fructose) to fructose 1,6-bisphosphate uses 2 molecules of ATP.

2. In the second set of reactions is known as the pay-off or energy-conserving phase, which is characterized by the net gain of energy-rich molecules such as ATP & NADP. i.e. 10 molecules of ATP

So the total net gain of ATP in glycolysis is 10-2 = 8 ATP in glycolysis

• In the pay-off phase, 2 molecules of G3P are produced. So each one gets converted to pyruvate and produces 1 molecule of NADH+ H⁺ + 1 molecule of ATP + 1 mol. of ATP.

Hence the total number of ATP produced when 1 molecule of G3P participates in aerobic respiration in most of the eukaryotes yields 2 ATP.
