  • Why would a throat infection cause heart damage?
    The immune response to the throat infection mistakenly attacks heart tissue due to molecular mimicry between streptococcal proteins and heart proteins.
  • What does the mimicry of streptococcal proteins to human heart proteins tell us about amino acid sequences?
    Similar amino acid sequences can produce similar 3D structures, leading to immune cross-reactivity.
  • What is incorrect about the statement: 'Different proteins always have different sequences'?
    Proteins can have similar sequences or motifs that result in similar structures, so this statement is false.
  • What does the immune system recognize in proteins?
    The immune system recognizes protein shape (3D structure), not just the amino acid sequence.
  • Are streptococcal proteins identical to human proteins?
    No, they are not identical but can have similar sequences that mimic human proteins.
  • Which protein function category does immunoglobulin belong to?
    Immunoglobulins belong to the protein function category of immune defense proteins.
  • How did immunoglobulin fail Jordan?
    Immunoglobulin failed by mistakenly targeting the heart due to molecular mimicry, causing autoimmune damage.
