If an enzyme in solution is saturated with substrate, the most effective way to obtain a faster yield of products is to
kompoz [17]

Answer:

a. add more of the enzyme.

Explanation:

Enzymes speed up the rate of reaction by lowering the activation energy for the reaction. They are not used themselves in the reaction. They are specific to substrate molecule. Substrate molecule binds to enzyme's active site and they undergo the reaction to form the product and release back the enzyme.

Rate of reaction depends on both substrate and enzyme concentration. Maximum rate of reaction is reached when all the active sites of enzyme molecules have been occupied by the substrate molecules which means that they are saturated. If more substrate is added at this point it wont have any effect on rate of reaction since there are no free active sites. Hence more enzyme is required to be added so that extra substrate can be utilized and rate of reaction can further be increased.

Which statement BEST describes why mycelium, constructed of hyphae, are necessary for fungi survival?
mariarad [96]

Answer:

Hyphae absorb nutrients from the environment and transport them to other parts of the thallus.

Explanation:

The large volumes of hyphae within the mycelium perform a fundamental role by obtaining nutrients from the organic substrates from the surrounding of the fungus. Hyphae play different kinds of functions in fungi.

They contain cytoplasm or cell sap. They also contain the nuclei, which include genetic material. Hyphae absorb nutrients from the environment and transport them to other parts of the thallus.

The thallus is the fungus body in which the fungi live or from beneath the soil to give support to the fungi for its growth and its survival.
