What is ATP energy in photosynthesis?

Key Terms

Where does the energy come from in photosynthesis ATP?

During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP.

What happens during photosynthesis with ATP?

Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.

Does photosynthesis use 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. Students should know in detail the chemical process of photosynthesis. ATP synthesis is associated with the electron transfer chain in the membranes of mitochondria.

Does photosynthesis make ATP?

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.

Do plants use ATP?

In addition to mitochondrial ATP synthesis, plants can also make ATP by a similar process during the light reactions of photosynthesis within their chloroplasts. This is an especially vital source of ATP for plants because ATP is also needed for them to synthesize glucose in the first place.

How much ATP is used in photosynthesis?

Three ATP molecules will be made, provided photosystem I recycles one electron in order to contribute two protons to the proton motive force.

How is energy released in ATP?

When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).

How is ADP converted to ATP?

ADP is combined with a phosphate to form ATP in the reaction ADP+Pi+free energy→ATP+H2O. The energy released from the hydrolysis of ATP into ADP is used to perform cellular work, usually by coupling the exergonic reaction of ATP hydrolysis with endergonic reactions.

How many ATP does photosynthesis produce?

Three ATP molecules
Three ATP molecules will be made, provided photosystem I recycles one electron in order to contribute two protons to the proton motive force.

What is the role of ATP in photosynthesis?

Adenosine triphosphate, or ATP, is an organic compound that provides energy for many different metabolic processes. In the chloroplasts, ATP is a product of the first stage of photosynthesis, and it provides energy for the second stage.

Where does the energy from photosynthesis come from?

Photosynthesis is a biochemical process in which plants, algae, some types of bacteria and protistans utilize the sun’s energy to produce sugar/glucose. At this point, they undergo cellular respiration, which converts the glucose into ATP (adenosine triphosphate), which is the fundamental fuel of all living things.

What are the products of photosynthesis in plants?

Photosynthesis is the name given to the set of chemical reactions performed by plants to convert energy from the sun into chemical energy in the form of sugar. Specifically, plants use energy from sunlight to react carbon dioxide and water to produce sugar (glucose) and oxygen.

How are ATP and NADPH produced in the light reactions?

In the light reactions, energy from sunlight drives the synthesis of ATP and NADPH, coupled to the formation of O 2 from H 2O. In the dark reactions, so named because they do not require sunlight, the ATP and NADPH produced by the light reactions drive glucose synthesis.
