At the start of translation, where does the initiator trna bind?

Answers

Answer 1
Answer:

Answer: start codon AUG of mRNA

Explanation:

The ribosomal assembly consist of two receptor sites, the P and A sites. The P site carries the peptidyl-tRNA, the growing peptide chain while the A site carries the new incoming tRNA with the amino acid to be added next.

The mRNA signal the initiation process with it start codon AUG. Because the start codon AUG codes for the amino acid methionine. A tRNA attach to methionine (tRNA-Met) binds to the start codon. The anti-codon UAC of the met-tRNA is correctly base pairing with the AUG codon on mRNA.

C. The site for lactic acid fermentation
D. The site for the Krebs cycle.

Answers

Answer;

D. The site for the Krebs cycle.

Explanation;

-Cellular respiration refers to the biochemical pathway by which cells release energy from the chemical bonds of food molecules and provide that energy for the essential processes of life. All living cells must carry out cellular respiration. It can be aerobic respiration in the presence of oxygen or anaerobic respiration

-The aerobic phases of cellular respiration in eukaryotes occur within organelles called mitochondria. These aerobic phases are the Krebs Cycle and the electron transport chain.


Answer is A and D, hope it helps
