B1.2 Proteins: grass skirts

18 quick questions on proteins, 10 of them at standard level, each answered in a word or two. Print a sheet for each team, a key for the checker and a tick sheet, then tape the sheets to the board and race.

How it runs

  1. SnipA runner cuts one strip off the bottom of their team’s sheet.
  2. Answer as a pairBack at the table, they write the answer on the strip. No books.
  3. Get it checkedThe checker reads it against the key: you, or a student holding it.
  4. Back for the nextA tick earns the next strip. Wrong? Back to the table to try again.

The questions on this sheet

The checker’s key, with every answer, prints with the sheets.
  1. Monomer of a polypeptide
  2. Part that differs among the 20 amino acids
  3. Joins two amino acids in a chain
  4. Product of condensing two amino acids
  5. Long unbranched chain of amino acids
  6. Loss of 3D shape caused by heat or pH
  7. Atom bearing the R-group of an amino acid
  8. Basic −NH₂ end of the backbone
  9. Acidic end of the amino acid backbone
  10. Must be eaten as the body cannot make it
  11. Sequence of amino acids in a polypeptide
  12. Coil stabilised by regular hydrogen bonds
  13. Overall 3D folding of one polypeptide
  14. Two or more polypeptides joined as one
  15. Compact, rounded, water-soluble shape
  16. Rope-like triple helix in skin and tendons
