how many molecules of atp are used in photosynthesis?
476591
It is a complex cycle of mostly phosphorylation (adding or removing phosphate) and oxidative (electron removal) chemical reactions whereby 6 molecules of CO2 are converted into one molecule of glucose. It requires the energy-releasing cleavage of high energy bonds of 18 ATPs and 12 NADPHs .

Answer: The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

When viewed as a whole, the photosynthetic process utilizes 12 water molecules, six carbon dioxide molecules and light energy to produce one glucose molecule, six water molecules and six oxygen molecules.

Adenosine 5'-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups. The word adenosine refers to the adenine plus the ribose sugar.

This accounts for about two ATP molecules. A total of 32 ATP molecules are generated in electron transport and oxidative phosphorylation.

ATP and NADPH produced by the light reactions are used in the Calvin cycle to reduce carbon dioxide to sugar. ... Carbon enters the Calvin cycle as CO2 and leaves as sugar. • ATP is the energy source, while NADPH is the reducing agent that adds high-energy electrons to form sugar.

How many oxygen atoms go into photosynthesis? Short answer: 24 oxygen atoms — in compounds — go into the photon energy driven synthesis of one glucose molecule.

The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.

ATP and NADPH produced by the light-dependent reactions of the photosystems are used by the Calvin cycle in the stroma of the chloroplast. Molecules of CO2 gas are fixed into molecules of 3-phosphoglycerate in a reaction catalyzed by the enzyme Rubisco.

Overall equation for photosynthesis 6 molecules of carbon dioxide are required, one for each carbon atom in glucose. 6 molecules of oxygen are produced as a by product of water oxidation. Sunlight provides the free energy needed to make the endergonic pathway proceed.

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. ... Without oxygen, much less ATP would be produced. Cellular respiration and photosynthesis are important parts of the carbon cycle.
332165
Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. ... Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).

We can now write a balanced equation for the net reaction of the Calvin cycle. Thus, three molecules of ATP and two molecules of NADPH are consumed in incorporating a single CO2 molecule into a hexose such as glucose or fructose.

Two of the most important energy-carrying molecules are glucose and ATP (adenosine triphosphate). These are nearly universal fuels throughout the living world and both are also key players in photosynthesis.

ATP Yield. 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.
