ATP is the energy currency of life that provide energy to the biological reactions. Kinases that phosphorylate their substrates require ATP. Membrane channel proteins that conduct active transport needs ATP. These proteins utilize the energy found in ATP, by breaking them in to ADP plus inorganic phosphate.
What else can I help you with?
What does motor proteins require to function in the movement of chromosomes toward the poles of the mitotic spindle?
Motor proteins require ATP (adenosine triphosphate) to function in the movement of chromosomes toward the poles of the mitotic spindle. ATP provides the energy necessary for motor proteins to move along microtubules and exert force on the chromosomes to move them to their desired location.
How much ATP does this cost the cell if it uses transport proteins?
The cost of ATP for a cell using transport proteins depends on the type of transport mechanism employed. For active transport, which moves substances against their concentration gradient, the process typically requires the hydrolysis of one ATP molecule per transport cycle. In contrast, facilitated diffusion through transport proteins does not require ATP, as it occurs along the concentration gradient. Therefore, if active transport is utilized, it costs the cell one ATP per transport event.
Does relaxation require ATP?
No, relaxation does not require ATP. ATP is primarily used for muscle contraction. Relaxation occurs when calcium ions are actively pumped out of the muscle cell, which does not require ATP.
What proteins require ATP to function?
Proteins that carry out active transport such as Na/K ion channels requires ATP. Also metabolic enzymes such as kinases which can phosphorylate its substrate also need ATP; For example hexokinase convert the glucose to glucose 6 phosphate in the first glycolysis step with the expense of an ATP molecule.The muscle protein myosin can use ATP to flex its head, pulling on the muscle protein actin, causing the actin filament to slide past the myosin filament producing contraction of the muscle. Sometimes myosin does this with just ion transfers without requiring ATP, but the reaction using ATP is more dependable.
What do mitocondrial and thylakiod membranes have in common?
They both use ATP synthase proteins in ATP production
Does transporting aquaporins proteins require ATP?
No, transporting aquaporin proteins does not require ATP. Aquaporins facilitate the movement of water across cell membranes through passive transport processes, such as osmosis or simple diffusion according to the concentration gradient. ATP is typically not needed for passive transport.
How do proteins in your cells access the energy stores in ATP?
Proteins in your cells access the energy stored in ATP by breaking down glucose. ATP will release energy any time the cells need to carry out functions that require energy.
What process changes the shape of transport proteins when a particle binds with it?
The process that changes the shape of transport proteins when a particle binds to it is called conformational change. This change in shape allows the protein to either open a channel for the particle to pass through or undergo a rotational movement to transfer the particle across the membrane.
What does motor proteins require to function in the movement of chromosomes toward the poles of the mitotic spindle?
Motor proteins require ATP (adenosine triphosphate) to function in the movement of chromosomes toward the poles of the mitotic spindle. ATP provides the energy necessary for motor proteins to move along microtubules and exert force on the chromosomes to move them to their desired location.
What do mitochondiral and thylakoid membranes have in common?
They both use ATP synthase proteins in ATP production
Does active transport require transport proteins?
Yes, active transport does require transport proteins. These proteins use energy to move molecules against their concentration gradient, typically from an area of low concentration to high concentration. This process is essential for maintaining cellular homeostasis.
Does relaxation require ATP?
No, relaxation does not require ATP. ATP is primarily used for muscle contraction. Relaxation occurs when calcium ions are actively pumped out of the muscle cell, which does not require ATP.
Do enzymes require ATP for their catalytic activity?
No, enzymes do not require ATP for their catalytic activity.
Does muscle relaxation does not require ATP?
Both muscle relaxation and muscle contraction require ATP.
Does the Calvin cycle require ATP for its functioning?
Yes, the Calvin cycle does require ATP for its functioning.
Does the process of endocytosis require the use of ATP?
Yes, the process of endocytosis does require the use of ATP.
Can glucose fats and proteins be respired to yield ATP?
Yes, glucose, fats, and proteins can be respired to yield ATP through cellular respiration. Glucose is the primary source of ATP, while fats and proteins can also be broken down and converted into ATP through different metabolic pathways such as beta-oxidation for fats and gluconeogenesis for proteins.
