Which R group would most likely be found in a hydrophobic area of the tertiary structure of a globular protein?
Nataly_w [17]

Answer:

CH2-Aromatic ring

Explanation:

Amino acids with aromatic R groups are relatively hydrophobic and therefore don't interact with water molecules surrounding the protein. Tryptophan (Trp), phenylalanine (Phe) and tyrosine (Tyr) are amino acids with aromatic R groups. Since these amino acids are relatively nonpolar or hydrophobic, they participate in hydrophobic interactions that are strong when there are several residues with aromatic R groups which are stacked on one another. In this regard, it is also important to highlight that Tyr and Trp are more polar than Phe due to the hydroxyl (OH-) group in Tyr and the nitrogen in the Trp ring.

What component of the cardiac muscles cells enables action potentials to pass easily from one cell to the next?
larisa86 [58]

A. Gap Junctions

Explanation - Cardiac muscle cell are able to contract in synchronized manner because of the gap junctions of intercalated discs. The action potential is expanded by the gap junction to support the coordinated contraction of the cardiac muscle.

Excitation contraction coupling or ECC is the process by which contraction of muscle occurs. It converts the electrical stimulus sent by the neurons to mechanical response to promote the movement of the muscle. Gap junctions thus helps in connecting the cardiac muscle cell.
