what is atp's role in photosynthesis?

ATP is an important source of energy for biological processes. Energy is transferred from molecules such as glucose, to an intermediate energy source, ATP. ... In photosynthesis energy is transferred to ATP in the light-dependent stage and the ATP is utilised during synthesis in the light-independent stage.

ATP is the main purpose for cellular respiration, whereas for photosynthesis, ATP is only needed in order to create glucose. ... Photosynthesis produces food whereas cellular respiration breaks down food. Photosynthesis occurs in the chloroplast of plants and cellular respiration occurs in the mitochondria of animal cells.

Photosynthesis occurs in the chloroplasts where the photosynthetic membranes, the so-called thylakoids are located. They are responsible for the light reaction whereby light is captured and its energy converted to chemical energy in the form of ATP and NADPH concomitant with the development of oxygen.

The stages of photosynthesis The light-dependent reactions take place in the thylakoid membrane. They require light, and their net effect is to convert water molecules into oxygen, while producing ATP molecules—from ADP and Pi—and NADPH molecules—via reduction of NADP+.

< Biochemistry. The electron transport chain is a system of molecules through which electrons are transferred to generate ATP. It has an important role in both photosynthesis and cellular respiration.

The light-dependent reactions produce oxygen gas and convert ADP and NADP+ into the carriers ATP and NADPH. ATP and NADPH provide the energy needed to build high-energy sugars from low-energy carbon dioxide.

In photosynthetic eukaryotes, the electron transport chain is found on the thylakoid membrane. Here, light energy drives the reduction of components of the electron transport chain and therefore causes subsequent synthesis of ATP.

Adenosine diphosphate (ADP) and adenosine triphosphate (ATP) both play important roles in providing cellular energy. When the cell needs to perform work, it removes a phosphate from ATP, releasing energy.
678832
In stage 4, the ATP and NADPH generated in stages 2 and 3 provide the energy and the electrons to drive the fixation of CO2 and synthesis of carbohydrates. These reactions occur in the thylakoid stroma and cytosol. Chlorophyll a is the only light-absorbing pigment in reaction centers.

Adenosine Triphosphate (ATP) Function in Cells. ATP is the main source of energy for most cellular processes. The building blocks of ATP are carbon, nitrogen, hydrogen, oxygen, and phosphorus. ... Thus, ATP functions as a reliable energy source for cellular pathways.
899118
Cellular respiration stores ATP, while photosynthesis releases ATP. Cellular respiration produces oxygen, while photosynthesis uses oxygen. ... Carbon dioxide and water released by cellular respiration are used in photosynthesis. Photosynthesis releases the energy that is stored during the process of cellular respiration.

The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.
823984
Fate of products of the light reactions Hydrogen and ATP are both transferred to the second stage of photosynthesis. Some of the oxygen produced can be used by the mitochondria of plant cells for aerobic respiration.

ATP – powering the cell. ATP (adenosine triphosphate) is the energy-carrying molecule used in cells because it can release energy very quickly. Energy is released from ATP when the end phosphate is removed. Once ATP has released energy, it becomes ADP (adenosine diphosphate), which is a low energy molecule.
1213153
ADP is adenosine diphosphate. It helps in formation of the energy currency i.e ATP, through it's attachment to one more phosphate group. The conversion of this ATP back to ADP releases the energy. Thus, helping in the process of photosynthesis.
1197674
Photosynthesis is the process by which green plants capture energy from sunlight and use it to make food molecules like glucose. Cellular respiration is the process used by plants and most animals, to convert the energy stored in food molecules into energy of adenosine triphosphate (ATP).
203456
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. ... While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
