Answer: Lipids.
- A Proteins
- B Carbohydrates
- C Lipids
- D Nucleic acids
Correct answer: C. Lipids
Explanation: Lipids include fats, oils, waxes, phospholipids, and steroids. They are insoluble in water and soluble in organic solvents.
As substrate concentration rises, reaction rate increases steeply at first, then plateaus at Vmax once every enzyme molecule is working at full capacity; Km is the substrate concentration giving half-maximal rate, and a LOWER Km means the enzyme reaches that rate with less substrate (higher affinity).
