Answer:

3. B, D

Explanation:

A primary source is an animal that eats only plants. (herbivore) A secondary source is an animal that only eats herbivores (carnivores)

B has birds; which are food for carnivores, and fruits, nuts, and blossoms; which are food for herbivores.

D has vegetables and grains; which are food for herbivores, and meat; which is food for carnivores

The other options have only food for carnivores, or only food for herbivores, so the answer is 3

Effector molecule binding changes the behavior of enzymes by altering the equilibrium between the tense (T) state and the relaxe

9966 [12]

Answer:

Explanation:

<h2>Homotropic effector-</h2>

$\text{accounts for the sigmoidal nature of a velocity versus substrate concentration curve}$
$\text{An enzyme's substrate.}$

$\text{Works by altering T/R ratio.}$

The phrase $\text{"accounts for the sigmoidal nature of a velocity versus }$

is relevant and can be applied for homotropic effector molecules since the heterotropic effector molecules have the possibility and affinity to change the sigmoidal curve to a more potential hyperbolic curve contingent upon the allosteric effector to be positive or negative modulator.

The expression isn't relevant for both homotropic and heterotrophic effectors since the two of them can tie to the allosteric site of allosteric enzymatic compounds.

The phrase $\text{"works by altering the T/R ratio"}$ is significant and can be applied for both homotropic and heterotropic effectors.

The expression $\text{"an enzyme's substrate"}$ is significant and applied for homotropic effectors just as when substrate molecules tie to the allosteric site of enzyme then it is regarded as homotropic effectors. The heterotropic effectors are effectors apart from substrate molecules.

The phrase $\text{"alters the} \ K_m \ \text{ of an enzyme"}$ is not applied and insignificant to none of the heterotropic or homotropic effector molecules since $K_m$ is significant for the enzymes that obey the Michaelis-Menten equation, but allosteric enzymes do not obey the Michaelis-Menten equation. Homotropic and heterotropic effectors are viable and efficient for allosteric enzymatic chemicals that don't contain
