How does ATP couple exergonic and endergonic reactions?
Energy is usually released from the ATP molecule to do work in the cell by a reaction that removes one of the phosphate- oxygen groups, leaving adenosine disphosphate (ADP). When the ATP converts to ADP, the ATP is said to be spent. Then the ADP is usually immediately recycled in mitochondria where it is recharged and comes out again as ATP.
What is one product of the light-dependent reaction?
The light dependent reaction produces two useful substances for the plant: ATP and NADPH. In addition it produces a waste product, oxygen gas. The ATP and the NADPH are then used in the light independent reaction. The oxygen is released into the atmosphere.
What is the name of the enzyme used in the ATP ADP cycle?
"If you remove just one of these phosphate groups from the end, so that there are just two phosphate groups, the molecule is much happier. This conversion from ATP to ADP is an extremely crucial reaction for the supplying of energy for life processes."
What is the role of atp sythase in photosynthesis?
The hydrogen ions pumped across the innermembrane into the thylacoid space fall down the electrochemical gradient through the ATP synthase where ADP is phosphorylated into ATP which is then used in the Calvin cycle rearrangements of carbon fixed intermediates to produce the gyceraldehyde-3-phosphate sugar the plants need. Simplified explanation.
Cellular respiration uses one molecule of glucose to produce?
Cellular respiration uses one molecule of glucose to produce what?
What reaction provides energy to power muscles?
The reaction that provides energy to power muscles is ATP. ATP loses one phosphate group and converts to ADP.
When ADP is created from ATP what type of reaction occurs?
break down of ATP into adp occurs when the one peptide bond of ATP is broken down.

What is a classic coupled reaction?
A classic coupled reaction is the hydrolysis of ATP, where energy released from the break down of ATP is used to drive an endergonic reaction. This coupling of reactions is common in many cellular processes, where the energy released from one reaction is utilized to power another reaction.
What is the role of ATP synthetase in the light dependent reaction?
In the presence of ATP synthetase enzyme ADP is converted in to ATP by uniting one more phosphate bond, storing chemical energy.
What is one product of the light-dependent reaction?
The light dependent reaction produces two useful substances for the plant: ATP and NADPH. In addition it produces a waste product, oxygen gas. The ATP and the NADPH are then used in the light independent reaction. The oxygen is released into the atmosphere.
What molecule acts as the energy currency for cell?
ATP
What is produced by reactions that take place in the thylakoids and are consumed by reactions in the stroma?
ATP and NADPH are produced by reactions in the thylakoids and are consumed by reactions in the stroma. The reason is because the reaction that takes place in the thylakoid is the light reaction and the one that takes place in the stroma is the light-independent reaction.
Does the nervous system release ATP into contracting muscle tissues?
ATP is required and used in may process by cells and it one action is indeed nervous system related. Activity-dependent release of ATP from synapses, axons and glia activates purinergic membrane receptors in muscles it is used as a signalling molecule. However, note that ATP is required for the shortening of actin and myosin filament crossbridges required for muscle contraction. This latter process is one of the main energy requirements of animals and is essential for locomotion and respiration. The source of this ATP is not from the nervous system.
What is the name of the enzyme used in the ATP ADP cycle?
"If you remove just one of these phosphate groups from the end, so that there are just two phosphate groups, the molecule is much happier. This conversion from ATP to ADP is an extremely crucial reaction for the supplying of energy for life processes."
Location of the storage of ATP?
ATP is made by the cells and is used for a variety of processess including various enzymatic reactions throughout the cell. ATP is mainly produced by the mitochondria and after production, it is dissipated within the cell for use by various reaction. However, mitochondria is one of the main storage organelle for ATP.
