Why are uncompetitive andmixed inhibitors generally considered to
Wittaler [7]

Answer:

The uncompetitive and mixed inhibitors are not affected by the substrate concentration while inhibition by a competitive inhibitor can be overcome by increasing the concentration of the substrate.

Explanation:

A competitive inhibitor competes with the substrate for the active site of the enzyme. When the competitive inhibitor combines with the enzyme and forms the enzyme-inhibitor complex (EI complex), the substrate cannot bind to the active site. However, the inhibition by competitive inhibitor can be overcome by increasing the substrate concentration around the enzyme which in turn would allow the substrate to bind to the active site and the reaction would proceed.  

On the other hand, an uncompetitive inhibitor binds to the site at the enzyme different from the active site. Once the ES complex is formed, the uncompetitive inhibitor joins the complex to inhibit the enzymatic activity.  

Likewise, a mixed inhibitor also occupies a site on the enzyme distinct from the active site for the substrate. A mixed inhibitor binds to the enzyme or ES complex to inhibit the reaction.  

Since the binding site for uncompetitive and mixed inhibitors are distinct from the substrate-binding site on the enzyme, increasing the substrate concentration can not overcome the inhibition.

Witch two examples show adaptations for plants growing the desert
gladu [14]

Answer and Explanation:

In some, the leaves are needle-like and stomata are reduced in number and located in cavities on the epidermis. A layer of moist air builds up in the cavity. This reduces the humidity difference between the intercellular air spaces in the leaf and the immediate external environment thus reducing the rate of transpiration.

In some the epidermis of the leaves is multilayered and is covered with a thick waxy cuticle which reduces water loss through evaporation, e.g. oleander. The cuticle is normally shiny which helps to reflect solar radiation preventing the leaf from heating up rapidly.

if a sponge was treated with a drug that specifically inhibited the activity of neuros and nothing else, what imoact would you p
Stels [109]

Sponges belong to the Phylum Porifera and hence are one of the most primitive organisms. The sponge would not be impacted by the drug.

Their bodies are asymmetrical. frame form can be cylindrical, vase-like, rounded or sac-like. they're diploblastic animals with layers, the outer dermal layer and the internal gastral layer. there's a gelatinous, non-cell mesoglea, in among these layers.

The phylum Porifera comprises the sponges. Sponges are simple invertebrate animals that live in aquatic habitats. despite the fact that the general public of sponges are marine, some species stay in freshwater lakes and streams.

Most sponges are hermaphroditic male and female cells exist in one animal and reproduce by using freeing spermatozoan into the water present day to be carried to other sponges, wherein they interact with eggs. Sponges also can reproduce.
