Answer: Unsaturated.
- A Saturated
- B Unsaturated
- C Trans
- D Essential
Correct answer: B. Unsaturated
Explanation: Unsaturated fatty acids have one or more C=C double bonds. Monounsaturated has one double bond; polyunsaturated has more than one.
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).
