Enzymes lower the activation for chemical reactions so they get a faster *Jump Start.* Once this happens these reactions can happen a lot faster than similar reactions or the same reaction
There are 4 types of RNA, each encoded by its own type of gene. ... mRNA - Messenger RNA: Encodes amino acid sequence of a polypeptide. tRNA - Transfer RNA: Brings amino acids to ribosomes during translation. rRNA - Ribosomal RNA: With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.
The answer is B. Speed up chemical reactions. Hope this helps.
