Answer: tRNA.
- A mRNA
- B rRNA
- C tRNA
- D hnRNA
Correct answer: C. tRNA
Explanation: tRNA (transfer RNA) carries specific amino acids to the ribosome during translation. Each tRNA has an anticodon that matches a codon on mRNA.
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).
