Fascinating Biochemistry Facts
Fascinating Biochemistry Facts 1. Your body makes water every day Through cellular respiration , mitochondria produce metabolic water. On average, an adult makes 250–350 mL of water daily just by breaking down food! 2. One human cell contains ~6 feet (2 meters) of DNA If you stretched all the DNA in your body end to end, it could reach the Sun and back ~600 times . 3. ATP is made and used at an unbelievable speed Your body recycles ~50–75 kg of ATP per day even though you only have about 50 grams in your cells at any time. 4. Enzymes can speed reactions by a factor of a trillion Without the enzyme carbonic anhydrase , CO₂ hydration in blood would be too slow to support life. With the enzyme, it becomes 1 million times faster . 5. Hemoglobin changes shape when it binds oxygen It flips between T-state and R-state , a beautiful example of allosteric regulation . 6. Your nose detects smells using GPCRs (G-protein coupled receptors) Humans have n...
