Answer:
Explanation:
Bacteriorhodopsin is one of the simplest protein from a family of a protein called opsin which is present in photosynthetic bacteria, algae and few fungi.
The bacterio-rhodopsin acts as an active light-gated proton pump which can pump the protons against their concentration gradient and then establishes concentration gradient across the membrane.
When the photosynthetic bacteria gets exposed to the light, bacteriorhodopsin pumps the proton from the cytosolic side to outside. This establishes electric motive force across the membrane which causes disequilibrium of protons.
The protons move back from the outside of the membrane to inside through H+ATPase which help allow the generation of ATP in the cell.

In creating products from trees with modern technology, only half of the trees can be used is false.
We all recognize that trees offer many useful products lumber for building production, furnishings, paneling, cabinetry, and floors, as well as paper of all sorts. however, tree merchandise moves ways beyond timber and paper. You are probably surprised at simply what number of tree merchandise you operate every day, and where they're located.
These encompass rayon garb, cellophane paper, cigarette filters, difficult hats, and sandwich bags. extra tree byproducts include chemical compounds extracted from bushes. these chemical compounds are used to make dye, pitch, menthol, and scented oils. By getting rid of carbon dioxide and returning oxygen, timber help preserves the stability between these gases within the surroundings, replenishing the oxygen removed through organisms and doing away with the carbon dioxide released via organisms.
