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.

Answer:
paleoclimatologists use different sources of information from fossils in order to record past climate and environmental conditions (for example, tree rings or skeletons of coral reefs)
Explanation:
Paleoclimatology is the discipline that studies ancient climate and environmental conditions. Paleoclimatologists are researchers that analyze different sources of evidence to obtain accurate records of past climate conditions. In this regard, the fossil record has proven to be a useful tool to obtain such information. For example, the rings of fossilized trees are usually wider during warm and wet years, while these rings become thinner during cold and dry years. Moreover, geochemical records from the skeletons of fossil corals (composed of calcium carbonate) are good indicators of past climate conditions because coral growth is sensitive to small fluctuations in water temperature. Paleoclimatologists also use non-biological climate indicators (e.g., sediments and ice sheets) to reconstruct past climate and environmental conditions.
Answer:
Es un río de agua dulce localizado en América del Sur que fluye desde los Andes en Perú, en donde el hielo provee agua a una altura de 5,998 metros, hasta Brasil, en donde desemboca en el océano Atlántico. Se encuentra a aproximadamente 192 kilómetros al este del océano Pacífico.

Answer:
Correct option is B.
Explanation:
Sympathetic nervous system is known as primary process to regulate the body fight or fight response, which is also called as sympatho adrenal response. This response end in the adrenal medulla which produce acetylcholine, and active the large secretion of adrenaline also known as epinephrine, and to a less extent noradrenaline or norepinephrine from it.
Sympathetic stimulation is constantly active, and maintain a basic homeostasis level in living organisms.
Explanation:
Any compound that has carbon atoms in its chemical formula is an organic compound.
