Isocitrate Dehydrogenase transforms isocitrate into alpha-ketoglutarate and is an important step in the citric acid cycle. This enzyme utilises NAD+ as a co-enzyme, NAD+ also acts as an allosteric inhibitor increasing the enzymes affinity for substrates. High ADP, High turn over of this enzyme meaning more citric acid cyle. Which in turn results in the high energy carriers that are donate electrons to the electron transport chain involved in pumping protons in the mitochondria.
Also Pyruvate dehydrogenase (pyruvate --> acety CoA) is an irreversible step which links glycolosis to the citric acid cycle, this too has its activity increased by ADP
What else can I help you with?
What is the specific name of the protein channel that makes ATP?
The specific name of the protein channel that makes ATP is ATP synthase. This enzyme is located in the inner mitochondrial membrane and is responsible for catalyzing the synthesis of ATP from ADP and inorganic phosphate during cellular respiration.
Does ATP syntaste produce ATP during cellular respiration?
No, ATP synthase is an enzyme that helps produce ATP from ADP and inorganic phosphate during cellular respiration by utilizing the proton gradient across the inner mitochondrial membrane. It does not directly produce ATP.
How is ATP made during the third stage of cellular respiration?
During the third stage of cellular respiration, known as oxidative phosphorylation, ATP is produced through a process called chemiosmosis. Electrons are transferred through the electron transport chain, creating a proton gradient across the inner mitochondrial membrane. As protons flow back into the mitochondrial matrix through ATP synthase, this enzyme harnesses the energy from the proton gradient to convert ADP and inorganic phosphate into ATP. This stage is the primary source of ATP, generating the majority of the ATP produced during cellular respiration.
What are pumped across the membrane of the mitochindria to drive ATP synthase?
Protons (H⁺ ions) are pumped across the inner mitochondrial membrane to create a proton gradient during cellular respiration. This gradient generates a difference in proton concentration and electrical charge, known as the proton motive force. As protons flow back into the mitochondrial matrix through ATP synthase, this energy is harnessed to synthesize ATP from ADP and inorganic phosphate.
Where in the mitochondria does ADP join with P to make ATP?
ADP and inorganic phosphate combine to form ATP in the mitochondrial matrix. This process occurs in the presence of enzymes involved in the electron transport chain and oxidative phosphorylation.
Is ADP a product of cellular respiration?
No, ATP is a product. ADP assists in the creation of ATP in cellular respiration.
Which step of cellular respiration uses high energy electrons to convert ADP to ATP?
The step of cellular respiration that uses high energy electrons to covert ADP to ATP is in the Krebs Cycle. The Krebs Cycle takes place in the mitochondria.
What is ATP converted to in respiration?
ADP + Pi
What is the enzyme that restore adp back to ATP?
The enzyme that converts adenosine diphosphate back into adenosine triphosphate is called 'ATP synthase'.
What is role is ATP and ADP play in cells?
ATP and ADP are used in cellular respiration to produce sugars. (ATP= energy)
What word is used to describe organisms which use oxygen in their cellular respiration pathways?
Oxidative phosphorylation. In this process ATP is synthesized from ADP that is coupled to the operation of the mitochondrial electron transport system.
What is the specific name of the protein channel that makes ATP?
The specific name of the protein channel that makes ATP is ATP synthase. This enzyme is located in the inner mitochondrial membrane and is responsible for catalyzing the synthesis of ATP from ADP and inorganic phosphate during cellular respiration.
Synthesis of ATP by the chemiosmotic mechanism occurs during?
The synthesis of ATP by the chemiosmotic mechanism occurs during cellular respiration, specifically in the inner mitochondrial membrane. This process involves the pumping of protons across the membrane, creating an electrochemical gradient that drives ATP synthase to produce ATP from ADP and inorganic phosphate.
Does ATP syntaste produce ATP during cellular respiration?
No, ATP synthase is an enzyme that helps produce ATP from ADP and inorganic phosphate during cellular respiration by utilizing the proton gradient across the inner mitochondrial membrane. It does not directly produce ATP.
The formation of ATP from ADP OS what kind of reaction?
Chemical, in respiration.
What two cellular processes energize ADP to ATP?
Photosynthesis and respiration
Which is a correct association of mitochondrion structure and respiration?
The mitochondrion has a double membrane structure, with an inner membrane involved in creating a proton gradient for ATP synthesis during aerobic respiration. The electron transport chain, a key process in cellular respiration, is located on the inner mitochondrial membrane.
