Across
  1. 2. A purine derivative that’s a little “off-track” from its DNA and RNA cousins—this molecule waits in the wings for a makeover into something more useful.
  2. 4. It's not a “codebreaker,” but it helps read the genetic message—often thought of as “the translator”.
  3. 7. This vitamin "gets activated" by sunlight, playing a crucial role in your bones—think of it as a sun-powered superhero for calcium absorption.
  4. 9. A protein that’s stronger than steel, yet spins its way into something light and delicate—nature’s fabric, woven by creatures of skill.
  5. 10. This molecule could be called ‘ATP’s cousin’—it helps in signal transduction, but doesn’t quite have the energy chops
  6. 13. These molecules are the ‘boundary setters’—one side loves water, the other hates it. They’re the foundation of your cell membranes.
  7. 14. This molecule's a ‘fatty’ character, but it’s also essential for your cell membranes and hormone production—just don’t overdo it!
  8. 15. These bonds are like molecular "handshakes," holding proteins together, but they’re only strong when the conditions are right.
  9. 17. The body's 'clean-up crew'—these sugar derivatives help tag waste for removal, making sure toxins don’t overstay their welcome.
  10. 18. These ‘sticky’ proteins recognize sugar molecules and can tell you a lot about cell recognition and signaling.
  11. 20. A polysaccharide with a secret mission—this molecule disrupts clot formation, but it’s not a cure-all; it works best when the body’s clotting needs are at their peak.
Down
  1. 1. The process that turns 'food' into ‘fuel’ for cells, and it’s a lot like a high school chemistry lab experiment.It’s not the most efficient energy source, but when oxygen’s scarce, this ‘old-school’ process steps in.
  2. 3. Like an enzyme, but can’t speed up reactions—the famous ‘helper’ molecule
  3. 5. Not vicious but viscous, ensures smooth movement of the joints.
  4. 6. A key player in your vision, this molecule changes shape when light hits it, allowing you to see—without it, the world would be a lot darker.
  5. 8. These enzymes are a bit like molecular locksmiths—they open up the door to DNA repair
  6. 11. The amino acid that’s a bit of a “mood maker”—while it’s known for building proteins, it also plays a role in helping you sleep.
  7. 12. The enzyme that ‘cuts the line’—inhibits one of the key steps in DNA replication. It relieves tension in the DNA as it unwinds, but overuse can “cut” the whole process short.
  8. 16. The “key” that unlocks the door for glucose to enter cells, but only when blood sugar levels rise—a delicate balance, too much or too little causes chaos.
  9. 19. The structure that helps enzymes fold correctly but can also ‘hold’ them together in tight spots.
