What else can I help you with?
What chemical binds to the muscle cell memebrane causing a temporary rush of what into the muscle cell?
Acetylcholine binds to the muscle cell membrane, causing a temporary rush of calcium ions into the muscle cell. This influx of calcium triggers muscle contraction.
How do halogen hobs work?
Halogen hobs use halogen lamps to create heat, which is then transferred to the cookware through radiation. When you turn on the hob, the halogen lamps heat up quickly, allowing for immediate cooking. They are known for their fast heating and precise temperature control.
What chemical does calcium oxide form when added to water?
When calcium oxide is added to water, it forms calcium hydroxide, also known as slaked lime, through a process called hydration. This reaction is exothermic, releasing heat as the calcium oxide binds with water molecules to form calcium hydroxide.
What does calcium chloride and hydrochloric acid form?
When calcium chloride and hydrochloric acid react, they form calcium chloride solution and release hydrogen gas as a byproduct. This is an exothermic reaction that occurs quickly.
Why does calcium react quickly with acid?
Calcium reacts quickly with acids because it is a highly reactive metal. When calcium comes into contact with an acid, such as hydrochloric acid, it undergoes a chemical reaction that produces calcium chloride, water, and hydrogen gas. This reaction releases energy and is typically accompanied by effervescence.
Is calcium in the halogen group?
No, calcium is not in the halogen group. The halogen group is made up of fluorine, chlorine, bromine, iodine, and astatine.
A protein that binds the calcium in smooth muscle?
Calmodulin is a protein that binds calcium ions in smooth muscle cells. When calcium binds to calmodulin, it triggers a series of intracellular signaling events that lead to smooth muscle contraction.
What happens when calcium binds troponin?
tropomyosin moves out of the groove between the actin molecules.
Is calcium a halogen?
No, calcium is an alkaline earth metal. The halogens are in the second column from the right on the periodic table.
Which is a hallogen poatssium or calcium?
Neither Potassium nor Calcium is a halogen since both are metals.
Does CaCl2 contain an alkali metal and a halogen?
Calcium chloride contains an alkali earth metal (calcium, a group 2 element) and a halogen (chlorine). There is no alkali metal. Alkali metals are group 1 elements.
How does fluoride protect your teeth?
it sticks to calcium and binds teeth together
What binds calcium ions in a smooth muscle causing contraction?
Contractions are initiated by the calcium-activated phosphorylation of myosin rather than calcium binding to troponin.
The binding of calcium to which molecule causes the myosin binding sites to be exposed?
Troponin binds to the Calcium ions to expose the actin to the myosin heads.
What binds with edta to prevent the blood from clotting?
calcium bind with the EDTA to prevent the blood from clotting
What is the next step in muscle contraction after the calcium ions binds to actin?
Actin changes shape.
What chemical binds to the muscle cell memebrane causing a temporary rush of what into the muscle cell?
Acetylcholine binds to the muscle cell membrane, causing a temporary rush of calcium ions into the muscle cell. This influx of calcium triggers muscle contraction.
