When this happens gasses dissolved in the magma are able to come out of solution, forming gas bubbles (the cavities) inside it. When the magma finally reaches the surface as lava and cools, the rock solidifies around the gas bubbles and traps them inside, preserving them as holes filled with gas called vesicles.

Pyruvate dehydrogenase is regulated by feedback inhibition and covalent modification. Which molecules inhibit the pyruvate dehyd

Oksi-84 [34.3K]

ADP, NAD+, CoA-SH, and pyruvate are the molecules that inhibit the pyruvate dehydrogenase complex.

<h3>What is pyruvate dehydrogenase complex?</h3>

PDC3 triggers the oxidative decarboxylation of pyruvate, resulting in the creation of acetyl-CoA, CO2, and NADH.

The PDC plays a crucial role in the oxidation of glucose by connecting the glycolytic pathway to the tricarboxylic acid cycle's oxidative pathway.

ADP, NAD+, CoA-SH, and pyruvate all inhibit it. PDK prevents glycolysis from being coupled to GO by inhibiting its target enzyme PDH.

Thus, the answer is ADP, NAD+, CoA-SH, and pyruvate .

Below are DNA sequences for two species. Identify how closely the species are related and what proves the relationship. Species

EleoNora [17]

Answer:

Option (B).

Explanation:

The relationship between closely related species can be studied by their evolutionary tree. The two species are closely related if they have similar characteristics and nucleotide sequence.

Species A has the DNA sequence TAGCTTAGGGACGG whereas species B has the DNA sequence TACCTTAGGGACGG. These two species have identical nucleotide sequence with minor differences. Hence, these two species are closely related with each other.

Thus, the correct answer is option (B).
