ATP synthase is a key enzyme in energy transformation of a living cell. The enzyme makes adenosine triphosphate (ATP) from adenosine diiphosphate (ADP) and inorganic phosphate (Pi).
ADP + Pi <=> ATP ATP is a universal "energy currency" of a living cell and is essential for DNA synthesis, muscle contraction, ion and nutrients transport, signal transduction, etc.
The amazing feature of ATP synthase is rotary catalysis: a complex of subunits rotates relative to the rest of the enzyme and the mechanical energy of rotation is driving ATP synthesis reaction.
In turn, the rotation is powered by transport of protons trough the membrane segment of ATP synthase. The driving force for this transport is the electrochemical potential difference of proton across the membrane.
ATP synthase is therefore the smallest mechano-electro-chemical energy transducer that works as a nanoturbine.

∙ 13y agoATP synthase is an enzyme that can synthesize ADP and phosphate to create ATP.
It is located in the mitochondrial membrane for the process of cellular respiration and the thylakoid membrane for the process of photosynthesis.
For both processes, when there is an imbalance of H+ concentration on either side of the membrane, a gradient is created.
In the mitochondria, there becomes more H+ concentration in the intermembrane space. In the thylakoid, there becomes more H+ concentration in the thylakoid space. In the mitochondria, this gradient causes H+ to move back to the matrix through ATP synthase.
In the thylakoid, this gradient causes H+ to move back to the stroma also through ATP synthase. As the H+ passes through ATP synthase for both processes, ATP is produced.

∙ 8y agoThe way ATP synthase works is that the 2 high energy electrons used in most of photosynthesis procedures with NADPH are converted into two separate molecules and carried between the chloroplast inner membrane. The ATP synthase controlls the course of those two molecules and carries them to different sections in the inner membrane thylakoids.

What is the role synthase in photosynthesis?
to produce ATP for the calvin cycle
Role of ATP synthase?
ATP synthase is a protein that synthesizes adenosine diphosphate (ADP) and an extra phosphate together into adenosine triphosphate (ATP). ATP is a very crucial molecule in body chemistry, and its primary function is to serve as an energy source for the vast majority of cellular functions. Therefore, the role of ATP synthase is to provide the energy that keeps cells functioning.
What spins to provide energy for adding a phosphate group to ADP?
The rotor part of the ATP synthase enzyme.
Where in the process of cellular respiration does ATP synthase make ATP?
ATP synthase is involved in making ATP + P at the membrane in the mitochondria. This occurs at the beginning of the Krebs cycle.
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.

When ATP synthase in activated it adds a phosphate group to what molecule?
ATP synthase catalyzes the addition of a phosphate group to an ADP molecule. ADP + ATP synthase + P --> ATP + ATP synthase (ATP synthase on both sides of the equation indicates that, as an enzyme, it is not used up in the reaction.)
What spins to provide energy for adding a phosphate group to ADP?
The rotor part of the ATP synthase enzyme.

Which protein complex allows hydrogen ions to rush out of the thylacoid providing energy that can be used to make a molecule?
ATP synthase allows H+ ions to pass through the thylakoid membrane.
What is the difference between ATPase and ATP synthase?
They both are enzymes related to ATP. The difference lies in that ATPase breaks down ATP while ATP synthase synthesizes ATP.
Where are the catalytic knobs of ATP synthase located?
The catalytic knobs of ATP synthase would be located on the stromal side of the membrane. Protons travel through ATP synthase from the thylakoid space to the stroma.
Where in the process of cellular respiration does ATP synthase make ATP?
ATP synthase is involved in making ATP + P at the membrane in the mitochondria. This occurs at the beginning of the Krebs cycle.
Which of these phosphorylates ADP to make ATP?
ATP synthase
What are enzymes that creates ATP called?
ATP Synthase
