This ion influx then travels down the cell membranes via T tubules and, via calcium channel complexes, leads to the release of calcium from the sarcoplasmic reticulum.

Eun Jo ahh.

And they can pull calcium out of the environment, put down a layer of calcium and then carbonate, calcium and carbonate.

Because Eun Jo is alone.

And then plus a hydroxide ion.

Plus a lithium ion.

Let's go, Eun Jo.

Eun Jo, what are you doing?

Ah. Where's Eun Jo?

Calcium is

But they're going to go and form negative ions.

Well the little hydroxide ion is going to pop off.

A cation is an ion with a positive charge.

Not talking about Eun Jo?

It's not different, it's the same stuff calcium carbonate, calcium carbonate.

That's the only calcium.

There, calcium.

And they said, calcium carbonate.

Calcium ion channel.

And this would just be the negative ion of fluorine.

Seung Jo and Eun Jo's lunches.

So you could end up with a hydronium ion.

And when the calcium channels they're voltage gated when it becomes a little more positive, they open calcium floods in and what the calcium does is, it bonds to these proteins that have docked these vesciles.

Chemical indicators Chemical indicators are small molecules that can chelate calcium ions.

Calcium supplements in America?!

Chloride becomes a negative ion and sodium is a positive ion, and they stick to each other really strongly because this guy's positive now, and this guy's negative after he took away his electron.

It's an ion because it has an extra hydrogen.

So people really care about the concentration of hydrogen of your hydrogen ions.

It completely disassociates in water into a hydrogen ion.

So this, right here, this is a negative ion.

So a , anion, means a negative ion.

Aigoo what's wrong? Eun Jo, you're cool too!

H2O, disassociating in itself, really, into a hydrogen ion in an aqueous solution plus a hydroxide anion in an aqueous solution or a negative ion.

So our body leeches calcium, phosphate out of the bones, takes the phosphate to neutralize the acidity, and then we pee out the calcium.

Address by Mr. Mircea Ion Snegur, President of the Republic of Moldova

Calcium is absent from his diet.

Calcite is calcium carbonate or CaCO3.

So maybe you have calcium.

Clacium would have filled out the 4s2 right?

Calcium has a plus 2 charge.

Medullary tissue is the calcium build up, the calcium storage basically, when an animal is pregnant, when a bird is pregnant.

Essentially, what was the calcium will bond and then it'll open up so the calcium can only exit the cell.
