Energy Concept
This week we explore a number of important concepts in Chapter 5 concerning energy and how reactions are facilitated in cells.
In this conference please provide a brief description of one of the following topics:
What is energy? The capacity to cause change, or to move matter in a direction it would not move if left alone. A child pushing a ball, the energy is transferred from the muscle of the child to the ball forcing the ball to move.
What is kinetic energy? The energy of motion, moving matter performs work by transferring its motion to other matter.
What does conservation of energy mean? The principle that it is impossible to destroy or create energy. Matter can transform kinetic energy (energy of motion) to potential energy (stored energy) and vice versa. In all such energy transformations, total energy is conserved. Energy cannot be created or destroyed.
What is potential energy? Stored energy, it’s energy that an object has because of its location or structure, such as the energy contained by water behind a dam or by a compressed spring.
How does ATP store energy? ATP stand for adenosine triphosphate, ATP consists of an organic molecule called adenosine plus a tail of three phosphate groups. The triphosphate tail is the end of ATP and each phosphate group is negatively charged. The Negative charges repel each other. The crowding of negative charges in the triphosphate tail contributes to the potential energy of ATP. For ATP power, it is release of the phosphate at the tip of the triphosphate tail that makes energy available to working cells. What remains is ADP, adenosine diphosphate. The transfer of a phosphate from the triphosphate tail to other molecules provides energy for cellular work.
What are enzymes and how do they work? A protein that serves as a biological catalyst, changing the rate of a chemical reaction without itself being changed in the process.
What is activation energy? For a chemical reaction to begin, chemical bonds in
