How much energy is released from the catabolism of one mole of glucose?

How many ATP are produced from 1 mole of glucose?

7 ATP are made per mole of glucose in glycolysis aerobically; but anaerobically, pyruvate is converted to lactate by lactate dehydrogenase at a cost of 2 NADH (5 ATP).

How much energy can a cell release from 1 mole of glucose?

According to the shuttle used to transfer H from cytosol to mitochondria. Free energy of ATP hydrolysis is 7.3 kcal/mol (30.5 kJ/mol); therefore, the total energy captured in the form of ATP per mole of glucose is around 277 kcal (1159 kJ). Combustion of 1 mole of glucose releases 686 kcal (2870 kJ).

How many ATP are produced in the catabolism of glucose?

In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.

How much energy does glucose release?

In total, the complete oxidation of a molecule of glucose to H2O and CO2 is used by the cell to produce about 30 molecules of ATP. In contrast, only 2 molecules of ATP are produced per molecule of glucose by glycolysis alone.

How is 34 ATP produced?

The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria.

Why is ATP 38 or 36?

In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH.

What is the efficiency of glucose metabolism if 1 mole of glucose gives 38 ATP energy?

686 kcal of energy is released. When 1 g of glucose respires aerobically by ETS, Glycolysis and Krebs cycle, around 38 ATP molecules are generated. The terminal group of a mole of ATP has around 10 kcal. Thus, 38 ATP molecules represent a yield of 380 kcal of energy.

How many moles of ATP are produced from 2 mole of glucose?

Anaerobically, each mole of glucose produces 2 moles of ATP. When there is adequate supply of oxygen, NAD reduced during oxidation of glyceraldehyde-3-phosphate transfers reducing equivalents from the cytosol to the respiratory chain by one of the shuttle systems (p. 199).

How many moles of ATP are produced from 1 mole of FADH2?

Every acetyl-CoA yields 3 NADH + 1 FADH2 + 1 GTP (=ATP) during Krebs cycle. Considering an average production of 2.5 ATP/NADH and 1.5 ATP/FADH2 using the respiratory chain, you have 108 ATP molecules.
