What is the flow of molecules in active transport?

1 answer:

6 0

Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient , using energy released during respiration .

Options are not provided in the question. The complete question is as following:

A researcher has performed a BLASTp search for a protein of interest. He identifies a globular protein that shares 30 percent of its amino acid sequence and positioning with his target protein. What can he conclude about the shape of his protein of interest?

a) It is also a globular protein.

b) It is a fibrous protein.

c) It has only a primary structure.

d) It demonstrates only pleated sheets as part of its structure.

e) The researcher can conclude nothing about his protein of interest.

Answer:

a) It is also a globular protein.

Explanation:

Globular proteins are one of the common form of protein (the other are fibrous, disordered, and membrane proteins) having spherical shape.

Protein-protein BLAST (blastp), This software returns the most related sequences of protein from the protein database defined by the user, provided a protein query.

So, the blastp has searched for globular protein.

Hence, the correct option is a.

explain how the understanding of atomic emission spectrum led to the development of the atomic theory

Ivahew [28]

Using hydrogen in his experiments Bohr showed that an electron spins around the atom nuclei at a specific/discrete radii (orbital levels). Electrons at every orbital level spin at a discrete angular momentum and energy. When the electron moves one orbital level down, it releases a photon of energy specific to the jump (that is, of a particular spectrum that is unique to the atom). When the electron goes up an orbital level, energy (of a specific spectrum) is absorbed. This emission and absorption spectrum varies across atoms and is calculated as (delta)E = hf where;

E = energy

h = Planck's constant

Explanation:

Neutralization Reaction:

When an acid and an alkali react chemically, they form water and a corresponding salt. This reaction called the neutralization reaction.
acid + base (alkali) → salt + water
E.g HCl + NaOH → NaCl + H2O
The formic acid that the ant injects can be neutralization by application of an alkali.
In order to prevent a serious allergic reaction, antihistamines must also be administered.
