The term that describes this process is - heat this term describes how hot or cold an object is - temperature The energy yield from food is in part determined by the efficiency of digestion - coefficient of digestibility Why do lipids contain more energy that carbs or proteins? - lipids are more energy dense because they have more hydrogen atoms that can be oxidized energy relates to the ability to do _____ - work the first law of thermodynamics is the.. - conservation of energy An object is dropped from the top of the building. Once the object is released and is halfway from the ground, the object has ... - kinetic energy only??? when a lipid molecule is broken down, energy is subsequently released. This is an example of an - exergonic reaction T OR F the second law of thermodynamics states that the transfer of potential energy in any spontaneous process always proceeds in a direction that increases the capacity to perform work. - falseTwo examples of energy conversion: - -photosynthesis (captures energy that we utilize as food and oxygen) - cellular respiration (energy released becomes conserved in compounds used for biological processes) T OR F enzymes are consumed during a reaction - false
