The primary products of the light independent reactions (after one turn of the cycle) are:
a) two G3P molecules
b) three ADP
c) two NADP+
However ADP and NADP+ are not really "products". They are regenerated and later used again in the Light-dependent reactions. Each G3P molecule is composed of three carbons.
For the Calvin cycle (Light independent cycle) to continue, 5 out of the 6 carbons provided by the two G3P molecules are used to regenerate ribulose 1, 5 phosphate. Therefore there remains only one carbon for the next turn of the cycle.
One molecule of glucose requires 6 turns of the cycle. Any extra G3P is used to make starch, sucrose and cellulose.
Transfer RNA (tRNA) carries amino acids to the site of protein synthesis.
In general , tRNA is responsible for carrying amino acids to the ribosomes, the site of protein synthesis, during the process of translation. Each type of tRNA molecule is specific to a particular amino acid. The tRNA binds to the appropriate amino acid and delivers it to the ribosome, where it is incorporated into the growing polypeptide chain according to the sequence of codons in the messenger RNA (mRNA) molecule.
This process ensures that the correct amino acids are assembled in the correct order to form a functional protein. Transfer RNA is a type of RNA molecule that plays a crucial role in protein synthesis. It has a unique cloverleaf-like secondary structure, with three important regions: The acceptor stem: This region is at the bottom of the cloverleaf and is where the specific amino acid attaches to the tRNA.
The anticodon loop: This region contains three nucleotides that are complementary to the codon on the messenger RNA (mRNA) during translation.
