.Proteins can be visualized in many ways, each of which highlights a specific aspect of the protein. Drag the terms on the left

ANTONII [103]

Answer:

1. Space-filling

2. Ribbon model

3. Wire frame

4. Simple shape

5. Simplified diagram

Explanation:

"attached is the question"

A protein can be visualized using different types of models. The models you use will depend on what you want the viewer to understand. A space-filling model would show all the atoms that composes a protein. This type of model makes use of spheres, emphasizing the globular structure of the atoms. They are proportional to the actual size of the atom they represent. Each type of atom is a different color. Even the distances of the spheres are proportional to its size to help viewers better see the actual shape of the protein. Ribbon model is also a 3D representation of a protein. It shows the only the backbone of the protein. It highlights the folds and coils in a protein, generally the organization. Some versions show the α-helices as ribbons and β-strands are shown as arrows. Wire frame model is like the ribbon model but it also shows the side chains. It shows the different atoms that are involved. Thin wires show the bonds made between the atoms and the wires bend show the relative location of the atoms. A simple shape focuses more on the function of the protein overall rather than the internal structures. The shape does not represent a particular protein, merely using a general shape to represent a protein. A simplified diagram shows more detail than the simple shape. It shows the internal structures as well but like the simple shape model, it focuses more on the function of the protein. A version of it is a solid shape, which does not show the internal structure.

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 .
