Hope this helps so sorry in advance if it’s wrong but hope it helps
Planet earth was probaly formed 30,thousand years ago the first life probably evolved 29 thousand years ago
"Neurons" are the functional unit of the nervous system; it is the specialized cells transmitting nerve impulses
Hope this helps!
An enzyme possesses different kinetics for different substrates as a result of this different products are formed.
Discussion:
- Multi-substrate reactions are governed by intricate rate equations that specify how and in what order the substrates bind. If substrate B is altered while the amount of substrate A remains constant, the study of these reactions becomes considerably easier. The enzyme behaves exactly like a single-substrate enzyme in these circumstances, and a plot of v by [S] yields the actual KM and Vmax constants for substrate B.
- These results can be utilized to determine the reaction's mechanism if a series of such measurements are carried out at various fixed concentrations of A. There are two different sorts of mechanisms for an enzyme that accepts two substrates, A and B, and converts them into two products, P and Q: ternary complex and ping-pong.
