Cell transport is useful because it's, essentially, the movement of cells across the blood/veins. Active transport uses energy, while passive transport does not.
Answer:Prokaryotes are organisms whose cells do not contain a distinct nucleus, bounded by a nuclear envelope, in contrast to eukaryotic organisms that do have distinct nuclei. Prokaryotes include both the bacteria and the archaea, which appear to be only distantly related to bacteria.
Explanation:
Answer:
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, ATP is produced directly in the reactions that transform glucose. However, more ATP is later produced in a process called oxidative phosphorylation.
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.
