WebbASK AN EXPERT. Science Physics A parallel laser beam of wavelength 633 nm is passed through a single narrow slit of width 0.1 mm, and the diffraction pattern is observed on a screen at distance 5 m. Calculate the width of the main intensity peak, defined as the distance between the two dark points on either side; give your answer in mm to 1 d.p. Webb19 okt. 2024 · December 23, 2024. In photosynthesis, the proton pump is responsible for transporting protons across the thylakoid membrane. This process creates a proton gradient that is used to generate ATP, the energy currency of the cell. The proton pump is thus essential for photosynthesis, and for the survival of plants and other photosynthetic …

In plants, HH -PPase is localized to the vacuolar membrane (the tonoplast). This membrane of plants contains two different proton pumps for acidifying the interior of the vacuole, the V-PPase and the V-ATPase. shredworks.comWebbspread of beam under Bragg peak.
