It is a light independent process in which the products of the light reaction (i.e., ATPs) are used to form carbon-carbon covalent bonds of carbohydrates. During this process ATP formed during light reaction are utilized. Hence the ATP energy is converted into carbohydrates, which are considered the energy-rich food.

What is the ATP used for in photosynthesis?
ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP. Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules.

What is the role of ATP in photosynthesis quizlet?
What is the role of ATP in photosynthesis? In light independent stage the energy carrier for the reaction that take place in the light dependent stage. ATP is also passed from light dependent stage to the dark stage to be used as energy in that process as well.

What is the role of ATP and ADP in photosynthesis?
When the cell has extra energy (gained from breaking down food that has been consumed or, in the case of plants, made via photosynthesis), it stores that energy by reattaching a free phosphate molecule to ADP, turning it back into ATP. The ATP molecule is just like a rechargeable battery.

What is ATP in photosynthesis short answer?
In photosynthesis, the role of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine diphosphate) is to carry the energy of the Calvin cycle that occurs in the absence of light. They are also called light-independent reactions.

What is ATP in photosynthesis for kids?
ATP is an energy storage molecule. NADPH is an electron carrier/donor molecule. Both ATP and NADPH will be used in the next stage of photosynthesis.

How is ATP energy used in photosynthesis?
Photosynthesis takes place in two distinct stages. In the light reactions, energy from sunlight drives the synthesis of ATP and NADPH, coupled to the formation of O2 from H2O. In the dark reactions, so named because they do not require sunlight, the ATP and NADPH produced by the light reactions drive glucose synthesis.

Where is ATP in photosynthesis?
In photosynthesis, ATP is synthesized from the thylakoid membrane (sites of the photochemical reactions of photosynthesis) of chloroplast cells of plants. The photon particles from the sunlight excite the chloroplast thylakoid membrane, which in turn converts this excitation into ATP’s chemical energy.

Where are ATP molecules used in photosynthesis?
The Calvin cycle takes place in the stroma and uses the ATP and NADPH from the light-dependent reactions to fix carbon dioxide, producing three-carbon sugars—glyceraldehyde-3-phosphate, or G3P, molecules. The Calvin cycle converts ATP to ADP and Pi, and it converts NADPH to NADP+.

How is ATP used in photosynthesis and respiration?
Cellular respiration uses glucose and oxygen to make carbon dioxide, water, and ATP. The molecule ATP is used for energy to run cellular processes. Carbon dioxide is released to the atmosphere where it is used in photosynthesis by plants. The process of photosynthesis uses ATP for energy to build glucose.

What is needed for ATP in photosynthesis?
Accumulation of protons occurs in the lumen of thylakoids protons return through the ATP synthase complex and catalyze the formation of ATP. This process is called photophosphorylation. The light energy absorbed by chlorophyll in the form of photons is used to generate high-energy electrons.

What is the role of ATP quizlet?
ATP provides energy to the cells to be used for: energy absorbing reactions (carb and protein synthesis). conduct nerve impulses across the nerve cells. It carries energy between Endergonic(energy-requiring) reactions and exergonic(energy-releasing) reactions.

What is the role of ATP in Stage 2 of photosynthesis?
Stage two: carbon fixation This stage also requires energy, which is supplied by the ATP made by the light reactions. The ATP is broken down to release energy which is used to combine hydrogen (from the light reactions) with carbon dioxide to produce sugar.

What is the role of ADP in photosynthesis?
ADP can be converted, or powered back to ATP through the process of releasing the chemical energy available in food; in humans, this is constantly performed via aerobic respiration in the mitochondria. Plants use photosynthetic pathways to convert and store energy from sunlight, also conversion of ADP to ATP.

What is the role of ATP and ADP?
ATP and ADP work together to provide cellular energy. ATP, as we mentioned, is like cash that can be used by a cell to perform work. To get energy, one of the phosphate groups is broken off from the ATP molecule, releasing energy. This leaves one free phosphate molecule and one ADP molecule left over.

How is ATP and ADP related to photosynthesis?
When a phosphate breaks off, through chemical reactions in a cell, energy is released which the plant uses for cellular processes. The lower energy Adenosine DiPhosphate (ADP) is then re-energized during photosynthesis as the phosphate group is re-attached, thus completing the cycle of ATP to ADP to ATP…

Does photosynthesis produce ATP or ADP?
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+.
