cellular respiration - Usable ATP Energy from glucose
Chapter 9 focuses on the process of Cellular Respiration. We begin by revisiting the idea that all living things need "energy" to carry out the processes of life. That "energy" is transformed from radiant energy to chemical energy through the process of photosynthesis. We look at several important ways that photosynthesis and cellular respiration are tied together as chemical processes which make life on Earth possible.
From there, we look more specifically at the process of Cellular Respiration. Cellular Respiration is a chemical process which takes place in the mitochondria of cells. It is a process which breaks apart molecules of glucose, releasing the energy they store to produce ATP - the molecules that cells use to "do work." Finally, we look at different ways cells produce ATP under different types of conditions. When you are doing intense work, you cannot deliver oxygen to your cells fast enough to carry out respiration.... so, how do your cells continue to produce the ATP they need? How do organisms that live in an environment with no oxygen manage to meet their energy needs? Fermentation. |

The best runners on Earth? The cheetah? The Gazelle? The Human? Well, it kind of depends - How long is the race? How intense is the pace? We might not be among the great sprinters, but we would be medal contenders in a long distance race. Check it out:
