The bulk of a cell's ATP must be produced in the mitochondria.

The Electron Transport Chain then produces 34 ATP molecules and H2O from the carrier molecules.

Experiments to show the uncoupling of ETC to ATP synthesis.

For each electron flowing from water to NADP+ (a net change in1.14 volts), two quanta of light are absorbed, one by eachPhotosystem. Each molecule of oxygen released involves the flowof four electrons from two water molecules to two NADP+s andrequires four quanta of sunlight absorbed by each Photosystem toprovide the energy to do this. These are the "Light PhaseReactions" of photosynthesis, which produce two high energychemical products, namely NADPH and ATP.

The conversion of ATP (top) to ADP (bottom) provides energy for the cells of the body.

RE: What is the equation for hydrolysis and dehydration synthesis?

Both the LHC and the reaction centers are membrane bound structures but there are no chloroplasts in the purple photosynthetic bacteria. The electron transfer processes occur within the cell membrane and the overall process is a cyclic one (i.e., there is no net oxidation-reduction). Protons are transferred across the membrane, from the cytoplasmic side to the outside, establishing a proton gradient whose dissipation drives ATP synthesis. A similar situation holds for the cyanobacteria and plants, but in these organisms, the process occurs in chloroplasts and the overall reaction is not a cyclic one.

How many ATP are produced in the electron transport chain located in the Mitochondria?

Hydrolysis Reactions (those that tear apart molecules) release energy from the molecules.

The overall equation for ATP hydrolysis is usually written: ATP + H 2 O = ADP + inorganic phosphate (Pi) DG o ' = -7.3 kcal.

5. What is ATP? Why is it an important product of cellular respiration?

taking water.CHEM 2423 Cyclohexene Synthesis Reaction Equation 2.

Oxygen is not consumed unless ADP and a phosphatemolecule are available, and these do not become available untilATP is hydrolyzed by some energy-consuming process.

When the ATP converts to ADP, the ATPis said to be .

Now what are the "Dark Phase Reactions" (aka CalvinCycle)? This is the cycle that converts CO2 into glucose. Sinceit utilizes the chemical energy in the ATP and NADPH, it does notrequire sunlight (hence the name). It is a complex cycle ofmostly phosphorylation (adding or removing phosphate) andoxidative (electron removal) chemical reactions whereby 6molecules of CO2 are converted into one molecule of glucose. Itrequires the energy-releasing cleavage of high energy bonds of 18ATPs and 12 NADPHs . The resulting 18 ADPs and 12 NADP+s are thenrestored by the Light Phase process to their high energy forms(ATP and NADPH).

Charging ADP to form ATP in the mitochondria is called .

Actually, the high energy content is not the result of simplythe phosphate bond but the total interaction of all the atomswithin the ATP molecule.

ATP-synthase converts ADP into ATP, a process called charging.

The Z Scheme diagram shows the pathway of an electron fromwater (lower right) to NADP+ (upper left). It also shows theenergy relationships which are measured as voltage potentialshown on the scaleon the right. To raise the energy of theelectrons derived from water (+0.82 volts) to the level necessaryto reduce NADP+ to NADPH (-0.32 volts), each electron must beboosted twice (vertical red arrows) by light energy absorbed inPhotosystems I and II. After each boosting , the energizedelectrons flow "downhill" (diagonal black lines) and inthe process transfer some of their energy to a series ofreactions which ultimately adds a phosporus to ADP to producehigh energy ATP and reduces NADP+ to NADPH. There is analternative shunt whereby the electron flow turns back tocytochrome b563 (green line)and this is called and it occurs when there is no need for NADPH, so onlyATP is produced.

They cannot add new phosphatesto an AMP molecule to form ATP.

We'll look at a simpler example of photosynthesis first, and use it as an introduction to photosynthesis in plants and cyanobacteria (blue-green algae). Although the primary reactions of photosynthesis take place at "photosynthetic reaction centers," the first level of interaction of light with an organism that carries out photosynthesis is at an assembly of chlorophyll molecules that "harvest" light (the "light-harvesting complex"). Such an assembly results in a greater chance that photons will be captured and, because of the strategic arrangement of the individual chlorophyll and other accessory light-absorbing molecules, the transfer of energy to the photosynthetic reaction center is very fast (-10 s) and very efficient (>90%).
