21 Ιουν 2016 · For decades, biological processes such as differentiation, tumorigenesis, and cellular aging have been thought to be irreversible. A stem cell loses its stemness during differentiation, while a differentiated cell cannot regain the stemness spontaneously.
We first need to define what is meant by a “reversible reaction.” The term “reversible” simply means that a reaction can proceed in both directions. That is, the things on the left side of the reaction equation can react together to become the things on the right of the equation, AND the things on the right of the equation can also ...
7 Απρ 2024 · Is plasmolysis a reversible process? Yes, plasmolysis is reversible. When the cell is placed back in a hypotonic or isotonic solution, it can regain its turgor through a process called deplasmolysis.
Let's look at an example of a reversible reaction in biology. In human blood, excess hydrogen ions (H +) bind to bicarbonate ions (HCO 3-) forming an equilibrium state with carbonic acid (H 2 CO 3). This reaction is readily reversible.
A reversible process is a process in which the system and environment can be restored to exactly the same initial states that they were in before the process occurred, if we go backward along the path of the process. The necessary condition for a reversible process is therefore the quasi-static requirement.
A reversible process is one in which both the system and its environment can return to exactly the states they were in by following the reverse path. An irreversible process is one in which the system and its environment cannot return together to exactly the states that they were in.
In simple words, the process which can reverse back completely is a reversible process. This means that the final properties of the system can perfectly reverse back to the original properties. The process can be perfectly reversible only if the changes in the process are infinitesimally small.
