- Your body stores energy in the form of fat and other organic molecules. When your body needs extra energy, it breaks apart the molecules of fat to release that energy (sometimes called "burning fat"). That energy is used to power cellular reactions or is lost as heat. The total amount of energy used by your body or lost as heat equals the amount of energy the molecules of fat originally stored before breaking apart. This process is an example of the _________law of thermodynamics. A. first B. secondZAV : j luui r Cuw pir:or Classroom docs.google.com a Adenosine triphosphate (ATP) is an important molecule because it is the result of catabolism release energy in uncontrolled bursts stores energy for use by body cells After you eat lunch, nerve cells in your stomach The fibrous membrane covering the outer surface of the bone is the periosteum epiphysisc endosteum diaphysis Cell membranes contain relatively few protein molecules. contain many carbohydrate molecules are freely permeable to electrolytes but not to proteins. have variable protein and lipid contents depending on themlocation in the cellI. have a stable composition throughout the life of the cell. The exocrine gland stores its secretion until the glandular cell ruptures, whereas the gland releases its apical region and reforms. holocrine; apocrineb eccrine; endocrinec apocrine; holocrined O O O O O O O O O O O OStarting as a lipid in some holiday prime rib, trace the path that energy and biomass make as that lipid is consumed by a college freshman, transported to a cell in the liver and converted into a carbohydrate, and finally as that carbohydrate is burned for energy in a cell in the cells of the shoulder muscles. Following your diagram/model, provide a written explanation for what you diagram/model depicts. Make sure both your model and explanation are clear, concise, and have the appropriate level of detail to clearly demonstrate you understand cellular respiration and the movement of mass and energy in animals. note;please include about the energy lost as heat hence,
- One food calorie = 1 X 103 calories = 1 kcal. A typical adult ingests about 2200 food calories per day. (A) show that an adult uses energy at about the same rate as a 100-W light bulb. {B) Calculate the total annual metabolic energy expenditure of the 6 X 109 people on the earth and compare it with the 4 X 1020 J per year energy used by the world economy. Assume all persons consume 2200 food calories per day, which is obviously incorrect.rank in order that releases most to least amount of energy adenosine triphosphate (ATP) acetyl phosphate phosphoenolpyruvate (PEP) glucose 6-phosphate (G-6-P) glucose 1-phosphate (G-1-P)When your muscles suddenly need a lot of ATP quickly; for example, if you decide to lift a couch over your head; what nutrient will provide most of the ATP for the first couple of minutes? O glucose carnitine O fatty acids O acetyl coA O vitamin B6
- Please construct a model to show that the digestive, respiratory, and circulatory systems work together to supply the body cells with the glucose and oxygen needed for aerobic cellular respiration. Feel free to use words, diagrams, arrows, flowcharts, etc. to get your ideas across. Make sure you include the following information: Digestion of starch into glucose and the location(s) of digestion. Absorption of glucose into the blood and the location of absorption. Blood transporting glucose from the absorption site to the tissues. Glucose entering the tissue cells from the blood. O2 entering the blood in the lungs and the specific location of entrance in the lungs. Blood transporting O2 from the lungs into the tissues. O2 enters the tissues from the blood.Which of the following accurately describes the energy during the biosynthesis of a fat molecule in plants: O Glucose -> fat molecule O Amino acids -> protein molecule O glucose -> starch molecule chemical energy -> heat and motion chemical energy-> chemical energy light energy -> chemical energyIn muscles, where it has been studied extensively, inorganic phosphate has been shown to significantly influence: Select one: O a. ATP synthesis O b. pyruvate availability O c. lactic acid mediated reduction in neuronal activity O d. muscle contraction
- describe how carbon, hydrogen, and oxygen from food may interact with other elements to generate amino acids and/or other big carbon-based compounds that make up the body's cells and tissues.Energy is the fuel that lets you enjoy all of the activities in your life. Excess en- ergy is stored in specific cells and locations in your body. Which of the following stores energy in your body? A dense connective tissue B Listen C D neuron reticular collagen adipose tissue6 The diagram below shows what happens to energy as it passes through an herbivorous mammal (a wildebeest). ticks 5% of this energy stored in tissue 60% of this energy passes through the wildebeest energy contained within food a i State the source of the energy in the food eaten by the wildebeest. State the form in which the energy is present in the carbohydrate eaten by the wildebeest. Name the process that makes the remaining 35% of the energy in the food available to the wildebeest. ii b i ii State three ways in which the energy may be used within the wildebeest. The bird on the wildebeest's back is an oxpecker that feeds both on blood-sucking parasites (ticks) living on the wildebeest, and on blood from the wildebeest's wounds. ci Drawa food web to show the feeding relationships of the organisms in the diagram. ii Explain why there must always be fewer oxpeckers than ticks in this food web.
