Chapter 4, Problem 2PIT
Summary Introduction
To determine:
Some examples of potential and kinetic energy except those given in concept map.
Introduction:
The energy possessed by a body when it is at rest is known as potential energy. The energy possessed by a body when it is in motion is known as kinetic energy. The sum of both the energies is always constant.

Students have asked these similar questions
Define potential energy and kinetic energy and provide two specific examples of each. Explain how one form of energy can be converted into another. Will some energy be lost during this conversion? If so, what form will it take?
While walking to biochemistry class with a friend, you see the following graffiti spray painted on the wall of the science building: “When a system is in equilibrium, the Gibbs free energy is maximum.” You are disgusted, not only at the vandalism, but at the ignorance of the vandal. Your friend asks you to explain.
Is dataG = Free energy? what is exactly is?

Define the exergonic and endergonic processes.arrow_forwardThe molecule can absorb heat from the environment without changing its chemical structure, as will occur when there is a local temperature increase. The molecule will have a higher energy. If the increase in energy is above KT (i.e., the entire environment has not increased its temperature), the molecule will come to thermal equilibrium with the environment around it, and return to its original energy state.

- Despite the thermal stability of covalent bonds in physiological systems, some of these bonds are sensitive to energy input from external sources. The molecule can absorb heat from the environment without changing its chemical structure, as will occur when there is a local temperature increase. If the increase in energy is above kT (i.e., the entire environment has not increased its temperature), the molecule will come to thermal equilibrium with the environment around it, and return to its original energy state. Which one of the following physiological process is example to this? Select one : a. Absorbance of light by 11-cis-retinal. b. Translucent to opaque conversion of egg whites after cooking. C.
