Science Learning: Enzyme tutorial in 4 minutes

Enzymes are the catalysts of living cells. If science learning requires an understanding of basic concepts, the function of enzymes in a chemical reaction is surely one of these important concepts. Here’s a short video to show you what enzymes Continue reading Science Learning: Enzyme tutorial in 4 minutes

Learning science: ATP hydrolysis

Learning science always comes back to learning basic concepts. ATP is a fundamental part of many critical processes of life. This week’s video covers ATP hydrolysis, the process by which ATP becomes ADP. Many important chemical reactions are powered by Continue reading Learning science: ATP hydrolysis

Science Learning: The flow of free energy in biochemistry

Science learning doesn’t have to be too complicated. One of the main keys to understanding biochemistry is to think about the flow of energy. The second law of thermodynamics is a core concept for science learning. This video covers the Continue reading Science Learning: The flow of free energy in biochemistry

Photosynthesis tutorial: The Calvin cycle in less than six minutes

The Calvin cycle is the companion to the light-dependent reactions in photosynthesis. The chemical reactions that make up the Calvin cycle are often called “the light-independent reactions” because they don’t involve light and chlorophyll. But this title is a little Continue reading Photosynthesis tutorial: The Calvin cycle in less than six minutes

Photosynthesis: Light-dependent reactions

Photosynthesis is a complicated subject! I’m in the process of making half a dozen videos to address it. If you want to see a simple overview of photosynthesis, check out this video: http://sciencetutoronline.com/blog/2012/08/14/a-simple-biology-tutorial-on-photosynthesis/ My latest photosynthesis tutorial covers the light-dependent Continue reading Photosynthesis: Light-dependent reactions
