(a) Give a simple example in nature to prove that light is a form of energy. (b) Give examples to prove (i) light energy changes into chemical energy. (ii) light energy changes into electric energy. View Solution Give one example to show that the sum of potential energy and kinetic ...
The energy possessed by virtue of speed is called the kinetic energy. The energy due to the position of an object in an external field is called the potential energy. If energy is stored in (the internal electromagnetic fields of) a chemical, then it is called ch...
Give an example of an enzyme found in a living organism. Describe the reaction it catalyzes and what is going on molecularly at the active site of that enzyme to allow it to do this. Describe the mechanism of enzyme action within chemical reactions. Include within your...
When growth hormone binds to an enzyme-linked receptor: (a) G proteins form a cascade of molecules and are phosphorylated (b) the enzyme portion of the receptor is dephosphorylated (c) the receptor is activated and phospho...

Examples of Endothermic and Exothermic Processes Photosynthesis is an example of an endothermic chemical reaction. In this process, plants use the energy from the sun to convert carbon dioxide and water into glucose and oxygen. This reaction requires 15MJ of energy (sunlight) for every kilogram of...
