which of the following statements about the role of ATP in cell metabolism is true? 1.ATP can diffuse through cell membrane 2.ATP is considered a low energy phosphate compound 3. ATP is present at high concentration in the cell. 4. Hydrolysis of ATP is strongly exergonic process.
Answers
Answer:
The free energy released by ATP hydrolysis that may be coupled to an endergonic process via the formation of a phosphorylated intermediate. As ATP begins to build up in a cell, metabolism slows down.
Explanation:
ATP is often called a high energy compound and its phosphoanhydride bonds are referred to as high-energy bonds. There is nothing special about the bonds themselves. They are high-energy bonds in the sense that free energy is released when they are hydrolyzed, for the reasons given above.
The electron transport chain of the cellular respiration process produces maximum ATP.
Answer:
The energy from the hydrolysis of ATP may be directly coupled to endergonic processes by the transfer of the phosphate group to another molecule.(Ans. 2)
Explanation:
ATP is a complex chemical which provides energy for many processes in living cells.
ATP hydrolysis is known as the catabolic reaction. High energy phophoanhydride bond present in adenosine triphosphate where chemical energy has been stored and released by splitting of these bonds. (high energy phophoanhydride bonds)
ATP is formed by the combination of ADP and phosphate group. The energy is released by the hydrolysis of ATP is used for the cellular works. This energy is mainly used by the coupling endergonic reactions with exergonic reaction of ATP hydrolysis.
