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.
What are the role of ATP and NADPH in photosynthesis?
ATP and NADPH are energy storage and electron carrier/donor molecule. Both ATP and NADPH are used in the next stage of photosynthesis. The chlorophyll molecule regains the lost electron from a water molecule through a process called photolysis, which releases dioxygen (O2) molecule.
What is the purpose of ATP in both cellular respiration and photosynthesis?
Both are processes within the cell which make chemical energy available for life. Photosynthesis transforms light energy into chemical energy stored in glucose, and cellular respiration releases the energy from glucose to build ATP, which does the work of life.
What are the roles 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. … When it’s run down, it’s ADP.
How does ATP form in photosynthesis?
In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. … The energy generated by the hydrogen ion stream allows ATP synthase to attach a third phosphate to ADP, which forms a molecule of ATP in a process called photophosphorylation.
What is the role of ATP?
Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. … ATP is commonly referred to as the “energy currency” of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups.
What is the role of ATP in Calvin cycle?
ATP and NADPH produced by the light reactions are used in the Calvin cycle to reduce carbon dioxide to sugar. ATP is the energy source, while NADPH is the reducing agent that adds high-energy electrons to form sugar. …
What are the roles of ATP and NADPH in photosynthesis quizlet?
What are the roles of ATP and NADPH in photosynthesis? Both of these molecules carry energy
