Where Will Atpase Be Found In The Mitochondrion?
Human mitochondrial (mt) ATP synthase or complex V consists of two functional domains: F1 situated in the mitochondrial matrix and Fo located in the inner mitochondrial membrane.
consists of two functional domains: F1 situated in the mitochondrial matrix and Fo located in the inner mitochondrial membrane.
Where in the mitochondria is ATPase found?
Where do you find ATPase?
The ATPase site is about 5 nm from the tip of the myosin head and is about 4 nm away from the actin-binding site of myosin.
What is mitochondrial ATPase?
Where is ATP synthase located in the chloroplast?
Which part of the mitochondrion contains a complex mixture of soluble enzymes that catalyzes the respiration of pyruvic acid and other small organic molecules?
What type of enzyme is ATPase?
ATPases are a group of enzymes that catalyze the hydrolysis of a phosphate bond in adenosine triphosphate (ATP) to form adenosine diphosphate (ADP). They harness the energy released from the breakdown of the phosphate bond and utilize it to perform other cellular reactions.
Is myosin an ATPase?
Is kinesin an ATPase?
In the steady state kinesin has a low ATPase activity that is limited by the rate of ADP release (< 0.01 s-1) in the absence of microtubules and is activated 2000-fold by the addition of microtubules to achieve a maximum rate of approximately 20 s-1. … ADP. P) from the microtubule following ATP hydrolysis.
Where is Phosphofructokinase found in the cell?
At least three-fourths of the phosphofructokinase activity in homogenates of Tetrahymena pyriformis is localized on the mitochondria. The mitochondrial phosphofructokinase activity is stabilized by ATP and by fructose 6-phosphate and is inhibited by ATP and by citrate.
Where is carbon dioxide produced in the mitochondrion?
Within the central compartment of the inner mitochondrial membrane are the Krebs cycle enzymes that in a cyclical series of chemical reactions break down the two-carbon fragments to carbon dioxide. As part of these breakdown reactions high energy electrons are produced.
Where does ATP synthesis takes place in mitochondria?
Where does etc occur?
The ETC reactions take place on and across the inner membrane of the mitochondria. Another cell respiration process the citric acid cycle takes place inside the mitochondria and delivers some of the chemicals needed by the ETC reactions.
How ATP is formed in chloroplast?
In an intact chloroplast with thylakoid membranes ATP is generated by an electron flow along the cytochrome transport system. Since the electrons are being transported to other “carrier” molecules their energy is used to generate ATP and no reddish glow is emitted.
What drives ATP synthesis in chloroplast?
In chloroplasts photosynthetic electron transport generates a proton gradient across the thylakoid membrane which then drives ATP synthesis via ATP synthase.
Where is NADP reductase enzyme located in the chloroplast?
NADP reductase enzyme is located on the outer side of lamella or thylakoid of the chloroplast. This enzyme causes breakdown of proton gradient to release energy i.e. NADPH.
Which part of the mitochondrion shown is its matrix?
Which of the following is the most acidic location in a mitochondrion?
The most acidic area of a mitochondria is the inner membrane space while the most acidic area of a chloroplast is the thylakoid membrane space.
How do protein complexes in the inner membrane of mitochondrion play important role in cellular respiration?
What is ATPase responsible for?
The Vacuolar ATPase (V-ATPase) is a proton pump responsible for controlling the intracellular and extracellular pH of cells. The structure of V-ATPase has been highly conserved among all eukaryotic cells and is involved in diverse functions across species.
What part of ATPase rotates?
What is the role of ATPase in photosynthesis and cellular respiration?
Plants produce carbohydrates and oxygen from carbon dioxide and water through the photosynthetic process. … Plasma membrane H+-ATPase a crucial enzyme for plant life acts as a primary transporter in fungi and plants. It actively transports H+ to extracellular spaces using the energy provided by ATP hydrolysis.
Which part of myosin has ATPase?
Which has ATPase activity?
Myosins are molecular motors possessing ATPase activity. There are many types of myosins differentially expressed in development and specific tissue type. Myosin II (conventional myosin) is the main myosin responsible for contractility of muscles and non-muscle cells.
What is myosin ATPase quizlet?
myosin ATPase enzyme in myosin head hydrolyzes an ATP molecule. energy released activates the head “cocking” it into an extended position. this is an endergonic process by changing the shape of the myosin head.
How was kinesin discovered?
Kinesin was discovered in 1985 – 25 years ago – based on its motility in cytoplasm extruded from the giant axon of the squid (Allen et al. 1982 Brady et al. 1982 Vale et al. 1985). … A large number of kinesin-related proteins were identified in rapid succession by sequence homology to Drosophila KHC.
What cargo does kinesin transport?
Kinesin transports cargo along microtubules The kinesin superfamily of proteins represents a large class of motor proteins that carry cargo along microtubules. The kinesin family comprises at least 45 isoforms in humans alone.
Where is the motor domain of kinesin?
Where is pyruvate kinase found?
Where does the synthesis of Phosphofructokinase occur?
In the liver the concentration of fructose 6-phosphate rises when blood-glucose concentration is high and the abundance of fructose 6-phosphate accelerates the synthesis of F-2 6-BP. Hence an abundance of fructose 6-phosphate leads to a higher concentration of F-2 6-BP which in turn stimulates phosphofructokinase.
Where is Phosphofructokinase synthesized?
What does the mitochondrion produce?

Where is carbon dioxide produced in the cell?
