Proteins can be visualized in many ways, each of which highlights a specific aspect of the protein. drag the terms on the left t
Nastasia [14]

Answer:

1. Space-filling

2. Ribbon model

3. Wireframe

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.

In the diagram below, which of the following represents the equilibrium? 1)a 2)b 3)c 4)d
Setler [38]

Answer:

4) d

Explanation:

In the given figure, <u>A is a wavelength</u> which is the distance between two crests of a wave. <u>B is a crest</u> which is the highest point located on a wave at maximum distance upward from the middle of the wave. C is a trough which is an opposite of crest meaning that it is the lowest point on a wave from the middle.

Lastly, <u>equilibrium</u> is a point located in the middle of wave. In other words, it is the average of crests and troughs located on a wavelength.

paragraph explaining how energy flows through energy pyramid trophinc level producer primary consumer desompsor sun secondary co
Kitty [74]

Answer:

Explanation:

Okay so, The Energy pyramid is the pyramid and order which energy is used and recycled. At the top of the pyramid you have the Animals at the top of the food chain such as humans, lions, ect. At the bottom you'll have, of course, things at the bottom of the food chain such as grass. How it works is the grass turns the sunlight into energy, which the grass is then consumed by an insect such as a grasshopper. The energy that was given to the grass is now in the insect. The insect gets consumed by one of its hundreds of predators, which is then consumed by the superiors of the food chain such as ourselves. Then of course we die then that's where the decomposers come in. Just munching on your remains and converts into the energy for mushroom. Then it starts all over again.

Comment on why do you think cells prefer to use carbohydrates as a source of energy before they use fats and proteins.
kompoz [17]

Answer:

This can be explained  based on structure, and on metabolisms of  carbohydrate.

Explanation:

Carbohydrate has a relatively simple structural composition than the  either protein or fatty acids. The C, H and Oxygen molecules are of  relatively fewer in number and few  chains than fats and protein.Thus  cells will spend less energy to break bonds(catabolisims) among these molecules during cellular respiration  pathways  to trap the energy.

In addition glucose the end products of carbohydrate did not need any processing before it enters glycolysis, Kreb's Cycle and oxidative phosphorylation pathways to generate energy for the cells.

Conversely, for protein to be used it has to be first deaminated(removal of amino acid) by the liver  before it enters glycolysis,while fats needs to  be broken down and undergo beta oxidation   with the long chains removed  before it can  form acetyl CoA. Therefore cells will prefer few steps, less endergonic  pathways of glucose than longer more endergonic amino acids  and fatty acid pathways.

Furthermore, glucose can be used in cellular respiration to  produce energy either aerobically or anaerobically, while fats can only be used anaerobically. Therefore, since cells usually prefer to thrive in aerobic conditions they  breakdown glucose easily during this period, and when lack of oxygen occurs they switched to anaerobic, Thus, the versatility of glucose to oxygen concentration makes glucose a better choice. Besides if fats was used anaerobically, ketone bodies build up which may be toxic to the cells.

anzhelika [568]
Option no. 2 a decrease in the release of oxygen gas

It is not simple because the process of growing crops, it needs more fertilizers, and processing the plants converting it to fuels needs a lot of energy. As much energy is used during the production from natural gas. The way of making biofuels it contains cellulose.
