# Question: When one mole of glucose is burned 2800 kJ of energy are released?

Contents

When one mole of glucose is burned, 2800 kJ of energy are released. However, when one mole of glucose is respired aerobically, only 40% of the energy released is incorporated into ATP. Each mole of glucose respired aerobically produces 38 moles of ATP.

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

No chemical reaction is 100% efficient – but how efficient is cellular respiration. The energy available in 1 mole of glucose is 686 kcal. Cellular respiration is able to produce 30 moles ATP from 1 mole glucose, and ATP contains 7.3 kcal per mole.

## What is the release of energy from glucose?

The source of the energy required to regenerate ATP is the chemical energy stored in food (e.g. glucose). The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration .

## How many molecules of ATP are produced from the metabolism of 1 molecule of glucose?

How Many Molecules of ATP Are Produced from 1 Molecule of Glucose? Theoretically, 38 ATP molecules are produced by complete oxidation of one molecule of glucose in aerobic respiration.

## How many kcal of heat is released when 1 mole of glucose is oxidized?

For each mole of glucose oxidized, about 686 kcal of energy is released.

## What is the efficiency of glucose metabolism if 1 mole of glucose gives 38atp energy ?( Given the enthalpy of combustion of glucose is 686 kcal 1atp 7.3 kcal?

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 much energy does one mole of carbohydrates release?

In aerobic respiration the net ATP produced is 38. One ATP yields approximately 10 kilocalories of energy. Thus, the energy liberated during the metabolism of one mole of glucose is 380 kilocalories.

## Where is the energy released in the glucose molecule?

Energy contained in the bonds of glucose is released in small bursts, and some of it is captured in the form of adenosine triphosphate (ATP), a small molecule that powers reactions in the cell. Much of the energy from glucose is dissipated as heat, but enough is captured to keep the metabolism of the cell running.

## What part of the cell releases energy from glucose?

Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.

## How is energy released in a cell?

In cells use oxygen to release energy stored in sugars such as glucose. In fact, most of the energy used by the cells in your body is provided by cellular respiration. Just as photosynthesis occurs in organelles called chloroplasts, cellular respiration takes place in organelles called mitochondria.

## How many ATP are produced from one glucose molecule during fermentation quizlet?

Cellular respiration results in 32 ATP made from a molecule of glucose. Fermentation makes no ATP itself, but allows glycolysis to continue, which has a net gain of two ATP. The Krebs cycle makes one ATP each time it cycles, which is twice for each original molecule of glucose, so it makes two ATPs.

## How many ATP does glucose produce in glycolysis?

During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi –> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O).

## How much energy is released by breakdown of glucose aerobically?

In aerobic conditions, the process converts one molecule of glucose into two molecules of pyruvate (pyruvic acid), generating energy in the form of two net molecules of ATP. Four molecules of ATP per glucose are actually produced, but two are consumed as part of the preparatory phase.

## How much energy is available when 1 mole of glucose is fully oxidized?

In respiration, 38 ATP molecules (or approximately 380,000 cal/mole) can be generated as biologically useful energy from the complete oxidation of 1 molecule of glucose (assuming 1 NAD(P)H = 3 ATP and 1 ATP → ADP + Pi = 10,000 cal/mole).
