Cell Energy SCI/230 9/28/12 Associate Program Material Cell Energy Worksheet Answer the following questions: * Cellular respiration: * What is cellular respiration and what are its three stages? * * Cellular respiration is the multi-step process in which oxygen is transformed within cells * producing carbon dioxide‚ the process purpose is transforming fuel intake into energy for cells. The three stages are glycolysis‚ citric acid cycle‚ and oxidative phosphorylation

Without this process the other half would not have anything to combine with to complete the DNA required to create a new cell. This would mean that reproduction of a new cell would not occur and the whole process would not be possible. Part 2: Photosynthesis and Cellular Respiration Matrix Complete the matrix. Use the following questions to aid in completion: • What is the purpose of this pathway? • Reactants: What does this reaction need to proceed? • Products: What is produced because

utilizable form is something essential for the functioning of any organism. Mitochondria and Chloroplasts are the two primary organelles in eukaryotic cells that involve in the transformation of energy‚ thus in production and consumption respectively. The chloroplast is an organelle present only in plant cells and some prokaryotes. At the same time they are absent in animal cells. It’s through the chloroplast that entry of energy to a cell takes place where sunlight is used to trap and convert carbon

DISCUSSION Photosynthesis is a process of converting light energy into chemical energy and storing in the bonds of sugar. Photosynthesis takes place in the plant leaves. In the leaves‚ there are mesophyll cells that have chloroplasts‚ where the photosynthesis occurs. During experiment‚ two leaves were tested for the presence and localization of starch. One leaf was a light-grown plant with mask‚ and the other was a dark-grown plant with mask. Both leaves were soaked in iodine solution and then
