"the tertiary structure of the human enzyme called lysozyme is stabilized by ionic bonds between the r-groups (side chains) of a

USPshnik [31]

The tertiary structure of the proteins is a three-dimensional structure. The polypeptides are arranged in a three-dimensional structure, which primarily arises because of the interaction between the side chains (R group) of the amino acids making up the protein.

The aspartic acid is a charged protein which is capable of forming the salt bridges. It can form ionic bonds with the R group of the other proteins. Hence, it can form ionic bond with the side chain of the amino acid lysine.

Hence, the answer is aspartic acid.

If one nerve stimulus arrives at a muscle fiber so soon that the fiber does NOT relax at all from the previous twitch, the most

BaLLatris [955]

Answer:

Complete Tetanus

Explanation:

The nerve stimulus arrives at the fiber at such a rapid pace that there is no decrease in tension between stimuli detected. This results in a tectanic contraction that is fused (complete) . Thus the muscle fiber does not relax at all due to this complete tetanus.
