Answer:
(B) They may have binding sites for regulatory molecules that are separate from active sites.
(C) They generally have more than one subunit.
(E) They interconvert between a more active form and a less active form.
Explanation:
Allosteric enzymes are the regulatory enzymes that have a specific site for binding of modulator or effector molecule. The activity of these enzymes is altered by the noncovalent binding of modulators at the allosteric site. The binding of the modulator brings about a conformational change in the allosteric enzymes.
The relatively inactive conformation of these enzymes is called T state while the active conformation is the R state. Most of the allosteric enzymes have multiple subunits and deviate from Michaelis–Menten kinetics and exhibit a sigmoid saturation curve of V0 vs. [S].
The best way may be is going over the notes on the chapter you were doing. Or going over the chapter once or twice.
Answer:
a. more widespread in the body and affect distant targets.
Explanation:
Hormones are released into the blood by the dustless endocrine glands and the circulating blood delivers hormones to cells throughout the body. Therefore, hormones affect the distantly located cells throughout the body. For instance, growth hormone released by pituitary gland affects soft and hard tissues throughout the body.
On the other hand, the nervous system release neurotransmitters that affect the postsynaptic neuron or the muscle or gland cells present close to the site of their release. Target cells of neurotransmitters are more limited and include muscle (smooth, cardiac, and skeletal) cells, gland cells, and other neurons only.
A bunch of the same critters. Nah I am just kidding, you will find a lack of resources because if they are all the same animals they will all eat the same thing. I hope this helps you.
