Summary Introduction

To determine: The maximum energy state attained by electron during the transfer from photosystem II to NADPH

Introduction: The electron moves in a zigzag manner through a series of energy changes that take place during photosynthesis. This is referred to as Z-scheme which has been proposed by Hill and Bendall.

Introduction The major context for this lab is photosynthesis, and the overall equation for photosynthesis is: 12 H2O + 6 CO2+ light energy → C6H12O6+ 6O2+ 6 H2O Exercise A: Photosynthetic Pigments Watch the following two videos about plant pigments and chromatography. To analyze the data we’ll give you, you’ll need to understand what types of pigments are found in a leaf, and understand some general characteristics of those pigments. Photosynthetic Pigments (~3 min) link:  https://www.youtube.com/watch?v=dwz3qozDiyI Leaf Color Chromatography (~4.5 min) link: https://www.youtube.com/watch?v=qH-AJDqsSII Answer the below questions :   Define the following terms: photosynthesis chromatography absorption spectrum action spectrum chlorophylls carotenoids (carotene and xanthophyll)   Referring to the Photosynthetic Pigments video, in the table below, write in the peak wavelength ranges absorbed by each of the following pigments. Include the colors that are associated with those…
Q no 2: Describe in detail what happens during the light reactions of photosystems. Use terms such as photosystems (be specific about which is which), pigments, reaction center, water-splitting, NADPH, ATP, ADP, NADP+, oxygen gas, etc?
Please answer fast  Many commercial herbicides act by inhibiting photosynthetic electron transport. They are investigating three herbicides for potential inhibitors of photosynthetic electron transport. a) How can you determine whether these substances have an inhibitory effect on photosynthetic electron transport? How can you quantify the effect? b) An inhibitor has produced a strong effect in "in vitro" tests, but the effect is significantly less in "in vivo" tests. What can be the reason for the reduced effect "in vivo"?
