Where does ATP in plants come from?
Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria; in plant cells, the enzyme also is found in chloroplasts.
What is the source of ATP in photosynthesis?
In plants, photosynthetic cells have two major systems for ATP production, photophosphorylation in chloroplasts and oxidative phosphorylation in mitochondria. In chloroplasts, the ATP production is connected to the reduction of NADP+ to NADPH as products of the photosynthetic light reactions.
What is the source of ATP?
Mitochondria are the main site for ATP synthesis in mammals, although some ATP is also synthesized in the cytoplasm. Lipids are broken down into fatty acids, proteins into amino acids, and carbohydrates into glucose.
Where is ATP produced in chloroplast?
chloroplast stroma
All electron-transport processes occur in the thylakoid membrane: to make ATP, H+ is pumped into the thylakoid space, and a backflow of H+ through an ATP synthase then produces the ATP in the chloroplast stroma.
What is ATP in plants?
Adenosine 5′-triphosphate, or ATP, is the principal molecule for storing and transferring energy in cells. Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules. …
What are three sources of ATP?
ATP is supplied via three separate sources: creatine phosphate, the glycolysis-lactic acid system, and aerobic metabolism or oxidative phosphorylation. THE HIGH-ENERGY PHOSPHATE SYSTEM; The amount of ATP present in muscle cells at any given moment is small.
Why is ATP a suitable source of energy?
ATP is an excellent energy storage molecule to use as “currency” due to the phosphate groups that link through phosphodiester bonds. These bonds are high energy because of the associated electronegative charges exerting a repelling force between the phosphate groups.
Does photosynthesis produce ATP?
The ATP is produced during the light reaction of photosynthesis by photophosphorylation. ATPs are produced towards the stromal side of the thylakoid membrane. In the formation of one glucose molecule, 18 ATP and 12 NADPH molecules are utilised in the six turns of the Calvin cycle. …
Do plant cells have ATP?
Most cells use ATP as their main form of energy. Most eukaryotic cells, including plant cells, get their ATP from the process of cellular respiration.
