In proteins, secondary, tertiary, and quaternary levels of structure depend on the primary structure.
Fittoniya [83]

Answer:b. Amino acid sequence, hydrogen bonding between backbone groups, the overall shape of a single polypeptide, and combinations of tertiary structures.

Explanation: Primary structure is the amino acid sequence in the polypeptide chain. When the sequence is altered due to mutation it can lead to formation of entirely new amino acid sequence.

Secondary structure could be the helical structure or the Beta pleated sheet. It is form from the interaction of atom that are backbones.It is the hydrogen bond between amino Hydrogen and carboxyl oxygen atom in the backbones

Tertiary structure- Overall structure of polypeptide. It result from interaction of the R groups amino acids. It gives the shape of the polypeptide.

Quantenary- Are protein made up of multiple polypeptide chain. This chain are also called subunit. It is the combination of all tertiary structures given rise to a functional protein.

Approximately what percent of fluid that exits the capillaries at the arterial end reenters the capillaries at the venous end
AnnZ [28]

Answer:

90%

Explanation:

The fluids leave the capillaries at the arterial end because the net filtration pressure of the blood is higher at the arterial end than it is at the venous end. The fluids reenter the capillaries at the venous end because the net filtration pressure of the interstitial fluid is higher at the venous end than it is at the arterial end.

Secondary active transportA) does not require the cell to invest energy, either directly or indirectly.B) is not carried out by
In-s [12.5K]
<h2>The correct option is (D)</h2>

Explanation:

  • The electrochemical gradients set up by primary active transport store energy, which can be discharged as the particles move down their slopes or gradients. Secondary active transport utilizes the energy put away in these inclinations or gradients to move different substances against their own gradients.
  • For instance, we should assume we have a high concentration of sodium particles or ions in the extracellular space. On the off chance that a course or route, for example, a channel or transporter protein is open, sodium particles will descend their concentration gradient and come back to the inside of the cell.
