Photosynthesis “deposits” energy‚ used carbon dioxide and water‚ and produces oxygen and glucose. By cellular contrast‚ cellular respiration “withdraws” energy‚ uses oxygen and glucose and produces carbon dioxide and water. b. The chemical energy of glucose

Results: The mealworms that were in the room temperature water have a higher cellular respiration rate than the mealworms in the cold water. This is because while they are in the cold water‚ the mealworm’s body slows down which decreases the amount of CO2 that is being produced. Unlike the mealworms in room temperature water‚ their cellular respiration was higher because their body temperature remained the same creating CO2 at a faster rate. Since there were two different controlled groups‚ there
Premium Carbon dioxide Energy Cellular respiration
Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? A living version of internal combustion-is the main way that chemical energy is harvested from food and converted to ATP energy‚ it is also called an aerobic process‚ which is just another way of saying that it requires oxygen. So cellular respiration is defined as the aerobic harvesting of chemical energy from organic fuel

the rate of aerobic cellular respiration in aquatic organisms which are Elodea (aquatic plant)‚ Snail‚ and Goldfish‚ by measuring carbon dioxide production. Because ectothermic organisms (Elodea‚ snail‚ and goldfish) were placed in completely covered beaker‚ each organism would produce different amount of carbon dioxide. The objective of the experiment is to measure carbon dioxide production in three aquatic organisms‚ and to determine and compare the rate of cellular respiration in each organism.

light-dependent reactions‚ dark (light-independent) reactions Previous knowledge: In 6th grade (6-2.7)‚ students summarized the processes required for plant survival (including photosynthesis‚ respiration‚ and transpiration). In 7th grade‚ students explained how cellular processes (including respiration‚ photosynthesis in plants‚ mitosis‚ and waste elimination) are essential to the survival of the organism (7-2.4) and explained how a balanced chemical equation supports the law of conservation

Note B: each answer requires more than one sentence & use diagrams whenever possible; failure to use diagrams will result in less points. Chapter 9 Outline 1) Principles of Energy Conservation a) Cellular respiration and fermentation are catabolic(energy – yielding) pathways b) Cells must recycle the ATP

starch‚ proteins and lipids What is the role of ATP? ATP is the driving force for catabolic and anabolic reactions. ATP stores energy that is produced from the catabolic reactions which is later released to drive the anabolic reaction and other cellular work. ATP is stored energy in cells (phosphate groups held together by high energy reacting bonds) ATP is required for synthesis and some of the energy is given off as heat What are enzymes and their components? Enzymes are biological catalysts
Premium DNA Metabolism Protein
Located in the cytoplasm‚ they are the sites of cellular respiration which ultimately generates fuel for the cell’s activities. Mitochondria are also involved in other cell processes such as cell division and growth‚ as well as cell death. They convert oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy "currency" of the cell that powers the cell’s metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen. Mitochondria
