I can only guess...some probable reasons maybe :
1. many cellular processes require ATP, hence there are many ATP binding proteins. Also, protein synthesis is a continuous process in the cell with a majority of cell wt being constituted by ribosomes. Hence, 2 different energy sources would mean less competition between enzymes for ATP binding.
2. During nutritional stress, protein synthesis occurs at an enhanced rate. Thus, there may be a functional need to de-couple energy status of the cell (decreased ATP) with protein biosynthesis. Although, I'm not sure if use of GTP is the cause or effect of this phenomenon(!)
What else can I help you with?
How many ATP and GTP used in protein synthesis?
In protein synthesis, one molecule of ATP is used to provide energy for forming peptide bonds during the elongation phase of translation. One molecule of GTP is used for each step in the initiation phase of translation when the ribosome assembles on the mRNA.
What codon is typically used as the start codon in protein synthesis?
The codon typically used as the start codon in protein synthesis is AUG.
Why ATP is needed not GTP for hexokinase reaction?
ATP is used in the hexokinase reaction because it acts as the source of phosphate for the phosphorylation of glucose to form glucose-6-phosphate. Hexokinase specifically recognizes and phosphorylates glucose, and it has a higher affinity for ATP compared to GTP. Therefore, ATP is the preferred energy source for this reaction.
What process is RNA used for?
Protein synthesis
What are the differences between the energy currency molecules GTP and ATP, and how do they impact cellular processes?
GTP and ATP are both energy currency molecules used by cells, but they have some key differences. GTP is mainly used in protein synthesis and signal transduction, while ATP is more versatile and used in various cellular processes like muscle contraction and active transport. The differences in their structures and functions allow cells to regulate different processes efficiently.
What is the product of protein synthesis?
A protein. That's what protein synthesis means.
What 4 bases are used in protein synthesis?
In DNA, the 4 bases are guanine, cytesine, thymine and adenine. In RNA, also used in protein synthesis, instead of adenine, there is urasil
Does protein synthesis occur during replication?
No, protein synthesis does not occur during replication. Replication is the process of copying DNA, while protein synthesis occurs during transcription and translation, where DNA is used as a template to create proteins.
Do you use the codon or anticodon to find the amino acid during protein synthesis?
During protein synthesis, the anticodon is used to find the amino acid.
What are the alternative start codons used in protein synthesis?
In addition to the commonly used start codon AUG, alternative start codons such as GUG and UUG can also initiate protein synthesis.
Structure responsible for protein synthesis?
Ribosomes, are responsible for protein synthesis.
What is the role of rRNA the protein synthesis?
it hold the protein synthesis in the ribosomes
