P4- Explain the physiology of two named body systems in relation to energy metabolism in the body.
Freeman (2008) furthers Eckert et al’s argument by stating that the actin filaments of the muscle cell in organisms are able to intake ATP (adenosine triphosphate) faster and will move the organism faster when higher temperatures are imposed. This is because of an increase in enzyme reaction rates (Freeman 2008). These arguments can be applied to our experiment to help explain the trends observed. It can be argued that as the Gammarus setosus experiences the cold treatments, the organ of Bellonci senses the cold temperature, which in turn signals the organism to preserve its energy to protect itself; therefore, the organism will swim slower. In addition, the enzymes in the muscle cells of the organism, when experiencing the cold treatments, will have decreased ability to carry out enzymatic reactions, therefore inhibiting the uptake of ATP, which will cause the organism to swim slowly. Conversely, as the organisms are put into the heated treatments, the organ of Bellonci senses the heat, and allows the organism to swim faster, since it does not have allocate as much of its energy towards survival. Furthermore, the enzymes in the cells will be able to catalyze reactions more quickly, therefore allowing the organism to swim faster. However, when the temperature of the surroundings is too high, the enzymes will denature, therefore, reducing the activity rate of
All of the chemical processes of the cell are called metabolism. The breakdown or degradation of complex organic molecules to yield simple molecules and energy is called catabolism. Anabolism is the total biosynthetic processes where large complex molecules are made from small simple molecules. Anabolic processes require energy because order is being created and thus work must be done. Overall, both processes of metabolism must occur concurrently because catabolism provides the energy necessary for anabolism.
direct calorimetry. Furthermore, the amount of oxygen in the chamber reveals the amount of cellular respiration of the organism. While also, test the effects of decreasing oxygen, and later increasing the heat on the metabolic rate of goldfish. I hypothesize that an increase in temperature will increase their metabolic rate
Introduction: Cellular respiration and fermentation are used in cells to generate ATP. All cells in a living organism require energy or ATP to perform cellular tasks (Urry, Lisa A., et al. , pg. 162). Since energy can not be created (The first law of thermodynamics) just transformed, the cell must get its energy from an outside source (Urry, Lisa A., et al. , pg.162). “Totality of an organism’s chemical reactions is called metabolism” (Urry, Lisa A., et al., pg. 142). Cells get this energy through metabolic pathways, or metabolism. As it says in Campbell biology, “Metabolic pathways that release stored energy by breaking down complex molecules are called catabolic pathways” (Urry, Lisa A., et al. pg.

Ectotherm processes, such as in crickets, will greatly depend on the temperature of their external source. Endotherms have the ability to maintain their constant body temperature in a wide range of environmental temperatures (Geiser 2004). When conditions become colder, they are able to raise their metabolic rate and produce more heat. If the temperature increases, they can decrease their metabolic rate and release heat through sweating and vasodilatation.
8. Thermoregulation is to regulate temperature. The hypothalamus sends signals to the blood vessels, muscles, and/or sweat glands to alter the temperature of the human body when needed. You should always keep your body at a steady temperature.
The purpose of this lab is to analysis goldfish an ectothermic animal affect toward different temperature ranges. The reactions toward the temperatures are taken upon the term of homeostasis, which is regulation for organisms to maintain a steady state while adapting to the conditions that are favorable for survival (Encyclopedia Britannica). In order to achieve a successful homeostasis, many animals use different methods of thermoregulation, which helps maintain the internal temperature of animals. Many methods vary whether the organisms is an endotherm or ectoderm. An endotherm, which includes mammals and birds, is a warm-blooded animal, which maintains a constant body temperature not influenced by the environment (Britannica).
Even more useful terms are Ectothermic or Endothermic, which suggest two different mechanisms of thermoregulation. Ectotherms generally obtain heat from
“Metabolism is the set of chemical reactions that happen in living organisms to maintain life. These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environments” (Metabolism). Metabolism breaks down the food that we eat, transforming it into energy for our bodies. Metabolism is broken down into two categories Anabolism and Catabolism, which help aid in the chemical reaction process. Specific proteins in the body control the chemical reactions of metabolism, and each chemical reaction is coordinated with other body functions (Dowshen). Metabolism is a constant process that begins when we're born and ends when we die. It is a vital process for all life not just humans, and
These four biomolecules are metabolized by the animal body. Each biomolecule is broken down in a different process. The end result of each process is the creation of usable energy for the body. This energy is used to work and generate other chemical reactions that help the body move and think. Carbohydrates, lipids, proteins and nucleic acids each provide energy to different places within the body that, in turn, stimulate other chemical reactions to occur, creating a chain reaction of chemical reactions throughout the body. The metabolization of these major
