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?

The Chemistry of Water 2

If I had to pick a single molecule that was the most important on earth, I would probably choose the water molecule. Last week I created the first video on the bipolar aspect of water. Its ability to readily form Continue reading The Chemistry of Water 2

Chemical Properties of Water

This week’s science learning video is about the emergent chemical properties of water. I’ll be getting into these properties in more detail in a future video, but today I’m going to cover the main chemical factor that enables many of Continue reading Chemical Properties of Water

Science Tutor Video on Chemical Bonds

This week’s science tutor video is a foundation for understanding the chemistry of inorganic matter, along with its implications for biology. I cover three types of chemical bonds, but I also get into the Van der Waals interaction because it Continue reading Science Tutor Video on Chemical Bonds
