The Adaptive Immune System Developed a Strategy for Monitoring the Proteins

question 8

Multiple Choice

The adaptive immune system developed a strategy for monitoring the proteins synthesized in virtually any cell in the body, thereby preventing pathogens from 'hiding out' by adopting an intracellular lifestyle. To accomplish this, the immune system:

• A) Co-opted the ubiquitin-proteasome system used by cell for protein turnover
• B) Created a novel pathway using the immunoproteasome for generating peptides
• C) Created a novel pathway to express foreign proteins on the cell surface
• D) Took advantage of proteolytic enzymes present in endocytic vesicles
• E) Engineered an immune-specific ubiquitin molecule for tagging foreign proteins

A small muscle in the lower leg that helps with foot eversion and extension of the toes.

Gastrocnemius

A major calf muscle that is involved in walking, running, and jumping, aiding in the bending of the knee and the plantar flexion of the foot.
