Which statements about allosteric enzymes are true?

Chemistry
1 answer:
Ainat [17]3 years ago
4 0

Answer:

1,2 and 4 are correct

Explanation:

Enzymes that show cooperativity are defined as Allosteric enzymes. This cooperativity is of several types.

1) homotropic/homoallestery - positive cooperation

2) heterotropic/heteroallestery - negative cooperation

Activity of allosteric enzymes is regulated by other molecules (effector molecules)

Hence, statement 1 and 2 are correct.

Binding curve of allosteric enzymes:

For cooperative binding, binding curve is Sigmoidal curve

For non cooperative binding, binding curve is Hyperboilc curve.

Hence, statement 3 is wrong.

Allosteric enzymes have multiple active sites.

Allosteric enzymes are often multi sub unit proteins.

Hence, statement 4 is correct.

What fraction of atoms in morphine is accounted for by carbon?
Yuki888 [10]
To determine the fraction of carbon in morphine, we need to know the chemical formula of morphine. From my readings, the chemical formula would be  <span>C17H19NO<span>3. We assume we have 1 g of this substance. Using the molar mass, we can calculate for the moles of morphine. Then, from the formula we relate the amount of carbon in every mole of morphine. Lastly, we multiply the molar mass of carbon to obtain the mass of carbon. We calculate as follows:

1 g </span></span> <span>C17H19NO<span>3 ( 1 mol / 285.34 g ) ( 17 mol C / 1 mol </span></span> <span>C17H19NO3</span>) ( 12.01 g C / 1 mol C) = 0.7155 g C

Fraction of carbon = 0.7155 g C / 1 g  <span>C17H19NO<span>3 = 0.7155</span></span>

Which statement describes the bonds in iron sulfate, FeSO4?
Feliz [49]

___

Regarding the bonds in FesO₄, Fe and S have an ionic bond, while S and O have covalent bonds.

Elements form bonds to increase their stability. The main types of bonds are:

  • Metallic bonds: they are formed between metals and the electrons are in a delocalized cloud.
  • Ionic bonds: they are formed between metals (lose electrons) and nonmetals (gain electrons)
  • Covalent bonds: they are formed between nonmetals, which share electrons.

Regarding the bonds in FesO₄:

  • Fe is a metal and S a nonmetal, thus they will form ionic bonds.
  • S and O are both nonmetals, thus they will form covalent bonds.

Regarding the bonds in FesO₄, Fe and S have an ionic bond, while S and O have covalent bonds.
