BIOL 101 quiz 3. how do physicists define "energy"? How would a cell biologist define "energy" ? the physicists definition of energy is not for use in defining energy changes within a living cell List 5 major sorts or categories of energy within the cell on a cold day, which of the following processes do your cells depend on to maintain an operating temp. of 37 degrees celsius? A. shivering B. muscle contraction C. respiration energy production D. metabolic heat generation E. all of the above Sometimes the cell pumps substance against diffusion forces that would carry those substances the other way. what term would you give to this process? Energy of concentration? is freely convertible from one form to another, but can never be created or destroyed. Systems that convert energy from one form to another are not 100% efficient, thus the amount of useful energy . In nature, as energy freely changes from one form to another, the total amount of energy . Becomes useless? In a crowded, unventilated room, what causes the temperature to rise? In living things, energy conversion is inefficient, with much energy being lost in the form of . A producer organism is called a "producer" because it produces usable . A lit match cannot continue to burn when the wood of the matchstick is consumed. This statement illustrates what general law of energy flow? What form of energy do producers use when they set about to generate chemical energy— the energy of C―H and C―O―H bonds? When your car engine burns the octane in gasoline, in what form does at least 50% of the energy of the octane end up? Existing chemical bonds between atoms are broken and new ones are formed between different atoms. In the broadest sense this is the definition for a . Give an example of a chemical reaction. Whenever chemical bonds are broken, energy is . Whenever chemical bonds form, energy is . Does an endergonic reaction require the input of energy, or does it give off energy? What term is given to the amount of energy required to break the bonds in reactant molecules?
