During translation, chain elongation continues until: a. the polypeptide is too long to fit in the cell. b. all the amino acids in the cell are used up. c. a stop codon is encountered. d. all the tRNAs are enzymatically broken down. e. the ribosome falls off the end of the mRNA.

C.

Explanation: It lasts until all the codons are read,so it encounters a stop codon.

the way that the mass of carbon can be conserved through cellular respiration is through a process/law called the law of conservation of mass which even tho it undergoes a process, mass is not be destroyed or changed
