Why do proteins have to have a 3d shape in order to function properly?

2 answers:

7 0

Protein is made up of a sequence of amino acids. The shape of the protein is usually characterize by the sequence of amino acids present. The functionality of protein is based on its shape. The shape of the protein can be a primary, secondary and tertiary. Tertiary structure of the protein allows it to interact or bind with other molecule in a specific way to perform a specific task.

Answer:

Proteins are the biomolecule present inside the the living organisms. Proteins are made of the polymers of the amino acids that are linked together by peptide bond.

Proteins are biologically active in its 3D conformation and shape. The 3D shape of the protein is achieved by the proper sequence of the amino acids and its folding. Any change in 3D structure of the protein will result in the loss of biological activity of the protein because of the alteration in the amino acid sequence. The 3D shape of proteins is important as it helps the enzymes to work properly to carry out chemical reactions of the body.

Which of the following is a good predictor of biodiversity in terrestrial ecosystems?

finlep [7]

The correct answer is - predator species in a community.

In the terrestrial ecosystems, a very good and usually sure predictor of the biodiversity is the existence of a predator species. The more predator species there are, the higher the biodiversity, and vice versa, the less predator species, the lesser the biodiversity.

The reason why the predators are such a good predictor of the biodiversity is that they are the species that are on the top of the food chain. That means that the predators are dependent for their survival on all the other species bellow them in the food chain, which is pretty much all species apart from themselves.

If a predator is present, than there has to be pray. If there's pray, omnivores and herbivores, than there has to be plants. All of the organisms are connected to one another, and the ones on the top of the food chain are the most dependent on the others, thus their existence usually means a healthy ecosystem with higher biodiversity.

A population of 1,000 healthy, at risk people is monitored for one year starting on January 1st, and the development of cases of

masha68 [24]

Answer:

$\mathbf{cummulative \ incidence = \dfrac{60}{1000}}$

Explanation:

We recognize that total occurrence equals new cases of disease over time divided by the number of people at risk at the onset.

Mathematically:

$\mathbf{cummulative \ incidence = \dfrac{New \ cases \ of \ disease \ occurrence}{Number \ of \ population \ at \ risk \ at \ onset}}$

Given that:

Number of the population at risk = 1000 individuals

New cases during Jan 1 - Dec 31 = 60 because;

At 20 occurred on June 30 & 40 on Sept. 30) & no new cases were identified after that:

∴

$\mathbf{cummulative \ incidence = \dfrac{60}{1000}}$
