Context: Energy, or the ability to do work, can exist in many different forms. The photo in Figure 17.8 represents six of the eight different forms of energy that are described in this lesson. The guitarist gets the energy he needs to perform from chemical energy in food. He uses mechanical energy to pluck the strings of the guitar. The stage lights use electrical energy and give off both light energy and thermal energy, commonly called heat. The guitar also uses electrical energy, and it produces sound energy when the guitarist plucks the strings. For an introduction to all these forms of energy, go to this URL: . For an interactive animation about the different forms of energy, visit this URL: After you read below about different forms of energy, you can check your knowledge by doing the drag and drop quiz at this URL: . Mechanical energy is the energy of an object that is moving or has the potential to move. It is the sum of an objects kinetic and potential energy. In Figure 17.9, the basketball has mechanical energy because it is moving. The arrow in the same figure has mechanical energy because it has the potential to move due to the elasticity of the bow. What are some other examples of mechanical energy? Energy is stored in the bonds between atoms that make up compounds. This energy is called chemical energy, and it is a form of potential energy. If the bonds between atoms are broken, the energy is released and can do work. The wood in the fireplace in Figure 17.10 has chemical energy. The energy is released as thermal energy when the wood burns. People and many other living things meet their energy needs with chemical energy stored in food. When food molecules are broken down, the energy is released and may be used to do work. Electrons are negatively charged particles in atoms. Moving electrons have a form of kinetic energy called electrical energy. If youve ever experienced an electric outage, then you know how hard it is to get by without electrical energy. Most of the electrical energy we use is produced by power plants and arrives in our homes through wires. Two other sources of electrical energy are pictured in Figure 17.11. The nuclei of atoms are held together by powerful forces. This gives them a tremendous amount of stored energy, called nuclear energy. The energy can be released and used to do work. This happens in nuclear power plants when nuclei fission, or split apart. It also happens in the sun and other stars when nuclei fuse, or join together. Some of the suns energy travels to Earth, where it warms the planet and provides the energy for photosynthesis (see Figure The atoms that make up matter are in constant motion, so they have kinetic energy. All that motion gives matter thermal energy. Thermal energy is defined as the total kinetic energy of all the atoms that make up an object. It depends on how fast the atoms are moving and how many atoms the object has. Therefore, an object with more mass has greater thermal energy than an object with less mass, even if their individual atoms are moving at the same speed. You can see an example of this in Figure 17.13. Energy that the sun and other stars release into space is called electromagnetic energy. This form of energy travels through space as electrical and magnetic waves. Electromagnetic energy is commonly called light. It includes visible light, as well as radio waves, microwaves, and X rays (Figure 17.14). The drummer in Figure 17.15 is hitting the drumheads with drumsticks. This causes the drumheads to vibrate. The vibrations pass to surrounding air particles and then from one air particle to another in a wave of energy called sound energy. We hear sound when the sound waves reach our ears. Sound energy can travel through air, water, and other substances, but not through empty space. Thats because the energy needs particles of matter to pass it on. Energy often changes from one form to another. For example, the mechanical energy of a moving drumstick changes to sound energy when it strikes the drumhead and causes it to vibrate. Any 
 Question: energy of an object that is moving or has the potential to move
answer:
mechanical energy


question:
Context: The protein alpha-synuclein (ASYN) is thought to be involved in the development of dementia with Lewy bodies (DLB). Overexpression of ASYN has been linked to cellular toxicity and human disease, and in experimental models, chaperones such as heat shock proteins (HSPs) are protective against ASYN toxicity. We have assessed the abundance of mRNA for ASYN and chaperones and the abundance and solubility of the encoded proteins in temporal cortex from sporadic human DLB. We found a reduction of ASYN mRNA in DLB (44.9% of control). The abundance of the Triton-soluble fraction (bioavailable protein) was not altered, but there was an increase of the Triton-insoluble component (likely representing aggregates). We evaluated 3 chaperones: HSP70, HSP90, and HDJ1. HSP70 mRNA was increased in DLB, whereas the mRNAs for HSP90 and HDJ1 were unchanged. HSP70 accumulated in the Triton-soluble fraction, whereas HSP90 and HDJ1 proteins accumulated in the Triton-insoluble fraction. These observations suggest that sporadic DLB is not associated with overexpression of ASYN. Rather, the persistence of normal soluble ASYN protein levels, despite the reduction of its mRNA, suggests a primary defect in clearance of the protein. However, this reduced clearance cannot be attributed to a failure of chaperone expression, because their mRNA is unchanged or increased in the DLB brain. 
 Question: Which is the primary protein component of Lewy bodies?
answer:

αsyn
