A mutation in human ATPase 6 from leucine to
arginine at position 156 may allow the movements of protons across the
membrane, but not rotating of the ring of c subunits.
This possible mechanism affect the function of
ATP synthase because there would be an uncoupling of proton translocation and ATP
synthesis. ATP synthase would remain sensitive to F0 proton conduction
inhibitors

Each tissue is an organized assembly of cells held together by cell-cell (more...) In epithelial tissue, by contrast, cells are tightly bound together into sheets called epithelia. The extracellular matrix is scanty, consisting mainly of a thin mat called the basal lamina, which underlies the epithelium.
The correct answer is co-adaptation.
Co-adaptation in biology refers to the procedure by which two or more species, phenotypic traits or genes go through adaptation as a group or pair. This takes place when two or more associating features go through natural selection together in response to the similar selective pressure or when selective pressures change one feature and simultaneously changes the interactive feature. These associating features are only beneficial when together, in certain cases resulting in increased interdependence.
The esophageal sphincter closes after a bolus has been swallowed and enters the stomach.
<h3>What is the esophageal sphincter?</h3>
The esophageal sphincter is a sphincter that separates the esophagus from the stomach. The muscle attached thereto pushes the bolus down the stomach.
Hence, esophageal sphincter closes after a bolus has been swallowed and enters the stomach. This sphincter is essential to prevent the contents of the stomach reentering the esophagus.
