IB Biology C1.2 Pub Quiz: Cell respiration

What it covers

IB Biology at SL, with HL cards when you switch the level: C1.2 Cell respiration.

The running order

nine rounds and a handout of riddles. Review rounds are drawn from this topic each time you open the quiz, so two classes never get the same paper, and every review round can be redrawn in a click.

1. Riddle me this review
   Course terms as riddles: "I have a head that loves water and two tails that hate it…" Teams write what it is.
2. Close-up fun
   A tiny zoomed-in patch. What's the full picture?
3. Fact or fiction fun
   Myths and true-but-weird facts. Teams write Fact or Fiction.
4. Think it through review
   Scenarios, odd ones out, true or false and why, puzzles: questions to reason through. Give teams a little longer.
5. Films in science-speak fun
   A film plot, described like a research abstract. Name the film.
6. Who am I? Scientists fun
   Three clues, hardest first. 3 points after clue 1, 2 after clue 2, 1 after clue 3.
7. Missing vowels: course terms review
   Your key terms with the vowels taken out.
8. Funny animal noises fun
   YouTube clips of animals making ridiculous noises. Screen off, listen, guess, then watch the reveal.
9. Closest wins fun
   Estimation questions. Nearest team wins the point. Doubles as the tiebreaker.

A taste of the questions

Think it through

Scenarios, odd ones out and true or false and why, from IB Biology.

1. Your red blood cells have no mitochondria. Which type of cell respiration keeps them supplied with ATP?
2. In the last 100 m of a 400 m race, a runner's leg muscles run short of oxygen. Which waste product builds up in them?
3. Anaerobic respiration gives far less ATP per glucose than aerobic respiration. Why do muscles use it at all?
4. I'm the cell's small change: snip off my end phosphate and a job is paid for on the spot. Why does a cell spend me rather than glucose?
5. A poison stops a cell making any ATP. Name one process in the cell that stops as a result.
6. Your muscles hold only enough ATP for a few seconds of sprinting, yet you can walk for hours. How?

Riddle me this

Course terms as riddles. Teams write what it is.

1. I'm a nucleotide with a tail of three. Snap off the end one and I pay for a job; put it back and I'm ready again. What am I?
2. I'm the cell's energy currency after it has paid for a job, one group lighter. Recharge me in respiration and I'm good as new. What am I?
3. I pile up in a sprinter's legs when oxygen runs short: the leftover of a quick, cheap way to make ATP. What am I?
4. I'm a sealed tube of seeds, a bead of coloured fluid and a little alkali. Watch my fluid creep and you'll know how fast they use oxygen. What am I?
5. I need no oxygen and pay out only a little ATP, but I'm quick when you're desperate. What am I?

Quickfire

Short recall from the same topics.

1. Cell's immediate source of usable energy
2. What ATP becomes after losing a phosphate
3. Splitting ATP using a water molecule
