Answer:
a. Always independently stable. Domain
b. Retains native structure even when separated from the rest of the protein. Domain
c. β Barrel. Motif
d. Calcium-binding segments of calmodulin. Motif
e. An advantageous folding pattern composed of two or more secondary structure elements. Domain
f. Sometimes independently stable. Motif
Explanation:
a. Protein domains are evolutionary conserved and stable 3D structures formed by a series of amino acids joined by peptide bonds.
b. Domains are stable because they conserve their tridimensional structure in physiological conditions even if they are separated of the rest of the protein.
c. The ß-barrel motif is a type of motif localized in single-stranded DNA viruses.
d. Calmodulin is a protein that contains calcium-binding motifs that enable to sense intracellular calcium levels.
e. Domain folding patterns are critical transitional states that allow the proteins their interaction with specific ligands in different physiological conditions.
f. Motifs are sometimes independently stable, but due to their short length (3-15 amino acids), protein motifs are generally unstable in different conditions.
Answer:
If the grasshopper is removed, the snakes will die, because the snakes have nothing to eat, and whatever eats snakes will die, and so on.
<span>The organelle responsible for the synthesis of fatty acids and steroid hormones is called smooth endoplasmic Reticulum. The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. It's main function is to produce lipids (fatty acids) and steroid hormones.Smooth ER also makes or distributes products according to its location. In muscle cells, it releases calcium ions because they are required for muscle contraction. In cells of the endocrine system, which is responsible for regulating hormones, smooth ER makes steroid hormones.</span>
