Answer:
the purpose of the translation is to make proteins. proteins are responsible for making bones, muscles, cartilage, skin and blood. proteins are synthesized from the information in a mRNA.
Process of translation
it happens in 3 phases
- initiation: the small ribosomal subunits binds to the start of the of the mRNA sequence. then a tRNA molecule carrying the amino acid methoionine binds to start codon of the mRNA sequence. after that large ribosomal subunit binds to form the complete intiation complex.
- elongation: the ribosome continues to translate each codon in turn each corresponding amino acid is added to the growing chain and linked via bond called peptide bond. elongation continues untill all the codons are read.
- termination: it occurs when the ribosome reaches a stop codon. since there is no tRNA molecules that can recognise these codons the ribosome recognises that translation is complete.
after these 3 phases a new protein is realeasd

Answer:
A proton gradient is generated by the transport of protons into the thylakoid lumen.
Protons move from the thylakoid lumen to the stroma through ATP synthase, producing ATP.
Explanation:
During photosynthesis, the environment is made acidic inside the lumen i.e. H⁺ are pumped into thylakoid lumen from stroma as a result of which more H⁺ are present in the thylakoid lumen as compared to stroma. It happens during light dependent reaction of photosynthesis. The concentration of H⁺ is already higher in lumen and transfer of more and more H⁺ from stroma increases the concentration of H⁺ even more leading to generation of a potential gradient. These H⁺ subsequently tend to move freely from lumen to stroma via "reverse pumps known as ATP synthase". The reason why these are known as reverse pumps is because pumps usually move particles from lower to higher concentration which is an active movement i.e. not natural so such movement requires energy. Naturally particles move from higher to lower concentration gradient until the concentration becomes equal on both the sides but pumps act opposite of this natural process and move particles from lower to higher concentration and utilize energy to do it. But here H⁺ are moving from higher to lower concentration which occurs naturally so ATP synthase rather than using energy tend to generate energy and this free energy is used to generate ATP from ADP & Pi (inorganic phosphate).
