Answer: Option B.
B. The chromaphore retinal absorbs a photon of light, causing a double bond in retinal to isomerize from trans to cis configuration.
Explanation:
Bacteriorhodopsin is a protein used by archaea or half bacteria that pumps proton across membrane by using the light energy from sun to move protons across membrane. It is found in purple membrane of archaea cells which is known as two dimensional crystalline patches.
It captures photon energy through chromophore retina which is covalently bound and transporting the photons against their electrochemical gradients from the cytoplasm to the extracellular space.
14.72 in percentage form is .1472
Answer:
Plant cells have cell walls, constructed outside the cell membrane and composed of cellulose, hemicelluloses, and pectin, a cell membrane similar to that of the animal cell, a large central vacuole, a water-filled volume enclosed by a membrane known as the tonoplast, they contain plastids, the most notable being chloroplasts, which contain the green-colored pigment chlorophyll that converts the energy of sunlight into chemical energy, and then all the other organelles of the animal cell (mitochondria, endoplasmic reticulum, nucleus and nucleolus, golgi apparatus, etc.)
