Inorganic ions are EVERYWHERE. ALL OF THEM EVERYWHERE. They’re up in your cytoplasm and all up in your tissue fluid and some of them are like super high in concentration like sodium and potassium while others are like uber low otherwise u dead. We talkin about hydrogen ions that determine pH which is the acidity or alkalinity of e.g. your blood. This is key to basically all the proteins circulating and all the cell reactions and everything.
Haemoglobin which is a good friend circling oxygen round the bod for max performance and non-dead status has iron ions at its core to actually bind the oxygen. Apparently we have an inch of an iron nail’s worth of iron in our body? BOO YAH IT’S ‘APPENIN.
Next it’s sodium ions which help transport glucose and amino acids into the body, and last we have phosphate ions making up DNA and ATP!
You explain everything so simply!

Hi! I have recently finished my first year doing biology at uni and I subscribed to you back when I was doing AQA A levels (glad I don’t live in Wales after watching this vid lol) and you and your website helped me so much. Just wanted to say it’s so nice to see you

Good topic notes and cool videos. I'll definitely recommend it to my students.
