Post your biology questions and biology answers here. That’s what this site is for. Someone asked me how it is possible specifically for enzymes to lower the activation energy of a chemical reaction. It came up with digestive enzymes that Continue reading Biology Answers: How do enzymes work?
This week I made a video tutorial on acids and bases. This is part 3 of the chemistry of water. In addition to a tutorial on acids and bases, I’ve also added in a bit about ocean acidification. Here’s the Continue reading Tutorial on acids and bases
This week’s science tutorial is about the periodic table of the elements. I assume you already know what the atomic number means, and you understand a little bit about orbitals and electron shells. (If not, go to this video science tutorial). Continue reading Science Tutorial on the Periodic Table
On Saturday I was making cinnamon rolls for my family. And it occurred to me how many chemical reactions take place in everyday processes. When I make a batch of cinnamon rolls, a lot of chemical reactions are taking place. Continue reading Chemical Reactions: A basic tutorial
I’m finally branching out, and adding a little bit of chemistry to my science tutor video series. This short (6-minute) science tutor video covers the established definitions of acids and bases. I’ve also put in a quick tutorial on the Continue reading Science tutor video: acids and bases
