Answer:
Allosteric enzymes bind at different site from the substrate binding site.
Explanation:
The activities of some enzymes, particularly those which form a part of a chain of reactions like metabolic pathways, are regulated internally. Some specific low molecular weight substances such as the products of another enzyme further on in the chain, acts as the inhibitor. Such a modulator substance binds with a specific site of the enzyme different from the substrate binding site. This binding increases or decreases the enzyme action. Such enzymes are called allosteric enzymes and the site at which they bind is called allosteric site.
Example: Hexokinase is an enzymes which converts glucose to glucose-6-phosphate in glycolysis. Decline in the enzyme activity by the allosteric effect of the product is called feedback mechanism, like the allosteric inhibition of hexokinase by glucose-6-phosphate,
Answer:
Activation of dendritic autoreceptors produce hyperpolarisations. A drug that is an agonist at these autoreceptors would be classified as an antagonist for the synapse.
Explanation:
Answer: Animals, plants, and bacteria.
Explanation: The phylogenetic tree is used to show similarities of organisms based on the genetics and possible shown features. Bacteria over time can evolve jus trike plants and animals, thus concluding that bacteria, plants, and animals can all be constructed on a phylogenetic tree.

The scarlet ibis (Eudocimus ruber) is a species of ibis in the bird family Threskiornithidae. ... Traditional Linnaean taxonomy classifies it as a unique species, but some scientists have moved to reclassify it as a ... More recent observation, however, has documented significant crossbreeding and hybridization in the wild.
