Difference Between ATPase and ATP Synthase

In simple terms, ATPase and ATP synthase are both enzymes which work for the phosphorylation reaction. Their function is antagonistic in nature. ATPase enzyme is commonly linked with the proton pump. ... On the other hand, ATP synthase is an enzyme used to synthesize ATP from using ADP and inorganic phosphate.

What is the function of ATPase?

Overview. The term ATPase applies to the activity of any enzyme's ability to decompose ATP, including metabolic enzymes involved in anabolic processes that need energy, as well as enzymes promoting transport across membrane.

What is the function of ATP synthase?

The function of ATP synthase is to synthesize ATP from ADP and inorganic phosphate (P_i) in the F₁ sector. This is possible due to energy derived from a gradient of protons which cross the inner mitochondrial membrane from the intermembrane space into the matrix through the F_o portion of the enzyme.

What is another name for ATP synthase?

"F-type ATPase" is just another name for ATP synthase; letter "F" comes from "phosphorylation Factor". F-ATPases are present in bacteria, mitochondria and chloroplasts. Their major function in most cases is ATP synthesis at the expense of the transmembrane electrochemical proton potential difference.

Does ATPase make ATP?

Most ATPases leverage the energy released from hydrolysis to either phosphorylate a molecule or change the conformation of ATPase and transport solutes against the concentration gradient. Reversible ATPases that can use a proton gradient to synthesize ATP or create a proton gradient upon ATP hydrolysis.

What enzyme breaks down ATP?

ATPase is an enzyme which breaks down ATP into ADP and free phosphate group.

How much ATP is used in the sodium potassium pump?

The Na+ K+ pump is an electrogenic transmembrane ATPase first discovered in 1957 and situated in the outer plasma membrane of the cells; on the cytosolic side. [1][2] The Na+ K+ ATPase pumps 3 Na+ out of the cell and 2K+ that into the cell, for every single ATP consumed.

What are the steps of ATP synthesis?

Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate.

What is the process of ATP synthesis?

ATP synthesis involves the transfer of electrons from the intermembrane space, through the inner membrane, back to the matrix. ... The combination of the two components provides sufficient energy for ATP to be made by the multienzyme Complex V of the mitochondrion, more generally known as ATP synthase.

Which structure is responsible for the synthesis of ATP?

The mitochondrion is referred to as the 'power house' of the cell, because it is responsible for the synthesis of the majority of ATP under aerobic conditions. The inner membrane of the mitochondrion contains the components of the electron transport chain.

What ATP does ATP synthase produce?

During electron transport, the participating protein complexes push protons from the matrix out to the intermembrane space. This creates a concentration gradient of protons that another protein complex, called ATP synthase, uses to power synthesis of the energy carrier molecule ATP (Figure 2).

What would happen if ATP synthase stopped?

The cell cannot survive without ATP. ATP is the energy source in cells so if our bodies did not produce ATP then the processes of active transport, cellular respiration and so on would stop working. The cells would start to die and eventually so would the organism itself.

How many ATP does ATP synthase produce?

Function of ATP Synthase

Each ATP synthase can produce about 100 molecules of ATP every second. Eukaryotes, such as plants, animals, and fungi, have organelles called mitochondria that mainly function as ATP producers.
