Which of the following is false regarding the protein pepsin?
Ilya [14]

Answer:

C. Pepsinogen is the active form of pepsin.

Explanation:

Pepsin is a gastric protease belonging to the aspartic proteinase family which breaks down polypeptide chains into smaller peptides by hydrolyzing peptide bonds. Pepsin is found in the gastric juice where it digests proteins from foods together with other digestive enzymes and hydrochloric acid. Moreover, pepsinogen is a precursor of pepsin which is secreted by the gastric chief cells of the human stomach and then is converted into pepsin (its active form) by hydrochloric acid.

Why do you think some bones, such as the humerus and femur, have rounded ends? Why do you think other bones, such as the vertebr
alekssr [168]

Answer:

1. Their rounded shape allow them to joint properly with other bones, permitting a softer, better motion.

2. Provide protection for specific organs and their shape provides a broad surface for the proper attachment of muscles.

Explanation:

The bone is a <u>connective tissue composed of specialized cells, a mineral-salt matrix, and collagen fibers</u>. The main functions of the bones are <em>organ protection, structure, red and white blood cell production and support.</em>

There are different types of bones:

  • Long
  • Short
  • Flat
  • Sesamoid
  • Irregular
  • Sutural

Some bones, such as the humerus and femur, are characterized by their rounded ends, also known as <em>epiphyses </em><em>(epiphysis - singular)</em>. The reason behind epiphyses is joint function. These bones are long bones, and their rounded shape allow them to ajoint properly with other bones, permitting a softer, better motion.

On the other hand, flat bones, such as vertebrae and carpals, provide protection for specific organs and their shape provides a broad surface for the proper attachment of muscles.
