Answer: adenosine triphosphate (ATP), is an energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
Explanation: Cells require chemical energy for three general types of tasks: to drive metabolic reactions that would not occur automatically; to transport needed substances across membranes; and to do mechanical work, such as moving muscles. ATP is not a storage molecule for chemical energy; that is the job of carbohydrates, such as glycogen, and fats. When energy is needed by the cell, it is converted from storage molecules into ATP. ATP then serves as a shuttle, delivering energy to places within the cell where energy-consuming activities are taking place. ATP is a nucleotide that consists of three main structures: the nitrogenous base, adenine; the sugar, ribose; and a chain of three phosphate groups bound to ribose. The phosphate tail of ATP is the actual power source that the cell taps. Available energy is contained in the bonds between the phosphates and is released when they are broken, which occurs through the addition of a water molecule (a process called hydrolysis). Usually, only the outer phosphate is removed from ATP to yield energy; when this occurs ATP is converted to adenosine diphosphate (ADP), the form of the nucleotide having only two phosphates. ATP can power cellular processes by transferring a phosphate group to another molecule (a process called phosphorylation). This transfer is carried out by special enzymes that couple the release of energy from ATP to cellular activities that require energy.
Uncontrolled production of cyclins will most likely result in uncontrolled division of the cell.
CELL DIVISION:
Cell division is a biological process that every cell undergoes to replicate themselves. It is the process by which cells are multiplied in living organisms.
According to this question, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell replication. However, at the end of the cycle, the cyclins are degraded to prevent further signaling for the cell to divide.
In a case whereby there is an uncontrolled production of cyclins, this will most likely result in uncontrolled division of the cell because cyclins stimulate cellulardivision.
Frogs have smooth or slimy skin that is moist, whereas toads have thicker, bumpy skin that is usually dry. All toads are poisonous, while frogs are not.
