If the researchers replaced the bacterial proton pump with a proton pump that was activated only by atp then less ATP would be produced when the light is on because no proton gradient would be available to produce ATP.
<h3>What is
proton gradient ?</h3>
Two quinol (4H+4e) oxidations at the Qo site result in the formation of one quinol (2H+2e) at the Qi site, creating a proton gradient (in total six protons are translocated: two protons reduce quinone to quinol and four protons are released from two ubiquinol molecules).
For the ETC to continue functioning, the energy trapped in the electrochemical gradient of protons across the inner mitochondrial membrane must also be released in some manner. ATP is created using the energy in the proton electrochemical gradient.
Chemiosmotic coupling is the process by which ATP synthesis is coupled to the electrochemical gradient of H+ across the inner mitochondrial membrane.
Peter Mitchell, who in 1961 made the initial suggestion, was given the Nobel Prize for his efforts in 1978.

Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. Atoms are composed of particles called protons, electrons and neutrons.
Answer:
In Hershey -Chase experiment , they proved the physical carrier of inheritance is nucleic acids not proteins.
Explanation:
Hershey- Chase <em>has proved genetic material is DNA. They experimented on Bacteriophage which are made of proteins and DNA. For this experiment they used radioactive isotopes of element. Phosphorous-32 was used to label the DNA and sulfur -35 was used to label amino acids in proteins.</em>
They found in experiment shortly after attacking on bacteria phage adhere on the surface, <u>inserts its DNA into the host , leaving its protein coat outside</u>. As they did not find any trace of sulfur-35 in the test medium.
after entering host body phage DNA multiplied in several copies. And after that they packed and assembled in protein coat.
After this experiment they concluded that DNA is the physical carrier of inheritance.
