Question

How many atp and gtp are required for polymerization of "50" amino acids?

Answer 1

Answer:

Two hundred molecules of ATP are converted into AMP + 400 Pi to activate the 200 amino acids, which is equivalent to 400 molecules of ATP. One molecule of GTP is required for initiation, and 398 molecules of GTP are needed to form 199 peptide bonds.

Answer 2

Explanation:

Answer:

20 ATP 50 GTP

Explanation:

• One GTP is hydrolyzed to GDP as each successive amino acid-tRNA complex attaches to the A site of the ribosome.

• A second GTP is broken down to GDP as the ribosome moves to each new codon in the mRNA.

• One ATP is hydrolyzed to AMP during amino acid activation.

• Thus, the formation of each peptide bond uses 3 high-energy molecules, one ATP and two GTP.
