Why are proteins not usually used for energy?

Allushta [10]

Turning amino acids into molecules that can be used in the Krebs cycle takes energy, which means that burning protein for fuel is not as efficient as burning carbohydrates. ... When amino acids are used as an energy source, it reduces the reserves of amino acids that are available for protein synthesis.

Which statement is a reason for the peer rewiew process in scientific research

andreyandreev [35.5K]

The correct answer is the second choice - peer review process in scientific research exists in order to verify that the conclusions that are made are supported by the data. You cannot make a valid conclusion if you do not have enough evidence or data to prove it - this is why your peers have to go through your research to make sure everything is done according to the rules of scientific research.

Hope this helps.

Community ecologists study the factors that determine the abundance of different species. The Abundance of three algae species (

Tema [17]

Answer:

Explanation:

Given that:

The abundance of three algal species in Lake A is now represented by the vectors:

[97, 84, 43] and [100, 80, 50]

Now if we look at Lake A, the change occurring in the vector of algae species can be determined as:

a = [100 -97, 80 - 84. 50 - 43]

a = [3, -4, 7]

Thus, the magnitude of that change is:

$|a| = \sqrt{(3)^2 +(-4)^2+(7)^2}$

$|a| = \sqrt{9+16+49}$

$|a| = \sqrt{74}$

$|a| =8.6 \ mg/mL$

The abundance of three algal species in Lake B is now represented by the vectors:

[25, 59, 22] and [20, 63, 15]

At Lake B, the change occurring in the vector of algae species can be determined as:

b = [20 -23, 63 - 59. 15 - 22]

b = [-3, -4, -7]

Thus, the magnitude of that change is:

$|b| = \sqrt{(-3)^2 +(4)^2+(-7)^2}$

$|b| = \sqrt{9+16+49}$

$|b| = \sqrt{74}$

$|b| =8.6 \ mg/mL$

Hence, for both Lake A and B, the magnitude of change is the same.

A researcher is carrying out an experiment where she labels a protein with a fluorescent tag (so she can visualize its location

melisa1 [442]

Answer:

The protein likely travels through a common lumen shared by thylakoid membranes and grana, and cannot easily diffuse through the thylakoid membrane.

Explanation:

There is a lot of scientific research in which a specific molecule can be labeled with some fluorescent marker (usually carbon 14). This type of marking allows the researcher to make observations about the movement of these molecules, as you can see in the question above. About the research shown in the question, the researcher realized that the protein labeled with the fluorescent marker moved between the grana and was always in the lumen, so she can conclude that the selocomovement protein moved through the lumen that is shared between the tilacoid membranes and the grana.

What is most noticeable structural difference between rna and dna?

fredd [130]

Structurally, DNA and RNA are nearly identical. However, there are three fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of deoxyribose sugar like DNA.
