Cellular Respiration - Exploring Nature
Cellular RespirationCellular Respiration Text, Diagrams, Assessments, and Link to Standards Focus Questions1) What is Cellular Respiration ?2) How is Cellular Respiration connected to breathing?3) If you are an athlete that exercises extensively, what organelles might you expect to see more of in your cells?4) How does eating food give our cells energy?When we eat and digest food, it is broken down into smaller and smaller units until it becomes small enough to be used in our cells as glucose molecules. At the same time, we are breathing in oxygen that travels from our lungs through our bloodstream into small and smaller blood vessels until it reaches our cells. When the glucose and oxygen reaches our cells, we have the materials we need to perform Cellular Respiration .
Fermentation uses the pyruvate molecules made by glycolysis from glucose. The formula is: C 6 H 12 O 6 (glucose) CO 2 + 2 C 2 H 5 OH (alcohol) and some energy In the making of wine and beer (alcohol), yeast cells generate ATP by the fermentation of the sugars in fruit and grain (in the absence of oxygen).
