What is the role of ATP in maintaining calcium concentration gradients?
Calcium must be actively pumped back into the terminal cisterns of the sarcoplasmic reticulum to terminate the contraction and relax the skeletal muscle. For every Ca2+ transported, one ATP molecule is hydrolyzed.
What is the electrolyte that plays an important role in the generation of nerve impulses?
Sodium, potassium, and calcium are the important electrolytes involved in nerve impulses
What is the function of smooth muscle in the bronchioles?
Cilia play very important role in bronchioles. They push the foreign particles outward.
What ions are important in the formation of membrane potentials?
Potassium and sodium are involved in the action potential present in the neurone. When a stimuli is detected Sodium is pumped into the neurone causing depolarisation this flow of charges causing a voltage known as the action potential. When the stimuli is no longer detected sodium and potassium flow out to cause repolarisation.
What is the parasympathetic ganglion that serves the eye?
the effects are ciliary muscle contraction leading to a constricted pupil and opening of the canal of schlemm to all aqueous humour drainage. Also there is an increase in tear formation. The PNS has a role in accomodation to light.
What is the role of the triad in muscle contraction?
Once a triad has been achieved, Calcium ions get released. Once they're released they bind to troponin, which helps begin muscle contraction.
Does calcium has any role in vasoconstriction?
Yes it does, as a matter of fact calcium plays a huge role in muscle contraction, as so in the smooth vascular muscle.
Role of ionic calcium in muscle contraction?
triggers neurotransmitter secretion, removes contraction inhibitor, and binds with troponin.
What helps muscles contract?
Calcium plays an important role in muscle contraction. Calcium is one of the most common minerals found in the human body.
Enlarged portion of sarcoplasmic reticulum on either side of a transverse tubule?
The enlarged portion of sarcoplasmic reticulum on either side of a transverse tubule is called a terminal cisterna. These terminal cisternae play a vital role in the excitation-contraction coupling of skeletal muscle cells. They store and release calcium ions, which are essential for muscle contraction.
What is the role of the tubules?
What is the function of the transverse tubules, is it the place where actin and myosin interact or the storage of calcium ions, or to transmit muscle impulses into the cell interior?
Are neourotransmiters calcium ions?
No. Calcium plays a role in making neurotransmitters cross a synapse. The neurotransmitters themselves are organic molecules, not ions.
What is the role of myosin APT ase in muscle contraction?
Myosin ATPase hydrolyze ATP into ADP+pi and yielding the energy required for muscle contraction.
What is the role of ATP in maintaining calcium concentration gradients?
Calcium must be actively pumped back into the terminal cisterns of the sarcoplasmic reticulum to terminate the contraction and relax the skeletal muscle. For every Ca2+ transported, one ATP molecule is hydrolyzed.
What is the function role of t tubules?
Enhance cellular communication passage for nervous stimulation during muscle contraction.
Is calcium a fiber?
No. Calcium does have a major role in muscle fibers when your muscles contract, but it is not the actual fiber.
What are calcium ions used for?
Well it has several important role in metabolism. Blood clotting is one of its significant role!
