Cellular Respiration

     In biology class Annie and I made a stop motion to show how cellular respiration works.  We used candy to represent different molecules.   Creating this project really helped me understand the confusing processes of cell respiration and also to learn all the details of it.  We had a lot of fun making this video and I hope you enjoy it!

Lionfish Invasive Species

     Recently, lion fish have invaded the florida keys and have been wrecking havoc there.  This prezi explains how the lion fish invaded, and also the extent of the damage they have caused.
     This video from the New York Times shows how some people are trying to put an end to this invasive species.

Krebs Cycle Explained



The Krebs Cycle is the second step in cellular respiration.  From one pyruvate, 3 CO2, 4 NADH, 1 FADH2, and 1 ATP are produced.  

Glycolysis Explained


This is a sketchfu showing how glycolysis works.  Glycolysis is the first step in cellular respiration, a decomposition pathway that provides all cells with energy.  Glycolysis requires one molecule of glucose and 2 molecules of ATP.  The outputs of Glycolysis are 2 pyruvates, a net gain of 2 ATP, and 2 NADH.
