Answer:
The given figure depicts the process of translation.
Translation is the process by which the mRNA is deciphered into the amino acid sequence of the polypeptide chain.
Ribosomes serve as the site of the translation.
The small and large subunits of the ribosome form the complex around the start codon of the mRNA.
It created three sites namely; A, P and E sites.
A site is a site where the charged tRNA enters the complex.
It then adds the amino acid specific to the codon sequence of the mRNA to the growing polypeptide chain at P site.
Uncharged tRNA then leave the complex through E site.
Answer:
requires that mitochondrial ATP synthesis and electron flow through the respiratory chain be obligately coupled.
Explanation:
The chemosmotic model was a concept formulated by Peter Mitchell, who stated that during the phases of electron transport in the respiratory chain, an intense release of energy occurs. This released energy allows hydrogen ions to be transported from within the mitochondrial matrix to the intercellular medium. The result of all of this is the occurrence of a chemosmotic gradient. However, when interpreting what occurs in the chemosmotic model, we can see that this model requires that the mitochondrial synthesis of ATP and the flow of electrons through the respiratory chain must be coupled.
