Answer: Amino acids.
- A Fatty acids
- B Amino acids
- C Nucleotides
- D Monosaccharides
Correct answer: B. Amino acids
Explanation: Proteins are polymers of amino acids linked by peptide bonds. There are 20 standard amino acids.
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).
