I believe that it's an exhausted bear. Cellular respiration is the way plants and animals receive energy. If the bear is exhausted, it means it's cellular respiration is lacking.
Answer:
Peptide bonds and Amino Acids
Explanation:
Primary structure. The primary structure of a protein refers to the sequence of amino acids in the polypeptide chain. The primary structure is held together by peptide bonds that are made during the process of protein biosynthesis.
Initiation:
In the cytoplasm, protein synthesis is actually initiated by the AUG codon on mRNA. The AUG codon signals both the interaction of the ribosome with m-RNA and also the tRNA with the anticodons (UAC). The tRNA which initiates the protein synthesis has N-formyl-methionine attached. The formyl group is really formic acid converted to an amide using the -NH2 group on methionine (left most graphic)
The next step is for a second tRNA to approach the mRNA (codon - CCG). This is the code for proline. The anticodon of the proline tRNA which reads this is GGC. The final process is to start growing peptide chain by having amine of proline to bond to the carboxyl acid group of methinone (met) in order to elongate the peptide.
Multifidus
What is multifidus?
The transversospinal group of deep back muscles includes the semispinalis, rotatores, multifidus, and other short, triangular muscles. They are shorter than semispinalis but longer than rotatores, and they are the thickest muscles in the transversospinal group. On either side of the vertebral column, from the cervical to the lumbar spine, there is a multifidus. Cervical multifidus, thoracic multifidus, and lumbar multifidus are the three regional subgroups of the group.
The spinal column is extended by the multifidus muscles. They contribute to the lateral flexion of the spine as well as some rotation of the vertebral bodies away from the side of contraction.
Multifidus: a muscle in the fifth and deepest layer of the back that helps to erect and rotate the spine by filling in the groove on either side of the spinous processes of the vertebrae from the sacrum to the skull.
