Of the following events from the light reactions of photosynthesis, which would be expected to occur first? While being split, electrons are taken out of water. Acceptance of electrons by Pc from the cytochrome complex Donation of electrons from reduced Pq to the cytochrome complex Light-induced reduction of the primary elecetron acceptor in the reaction center of PS Il takes place.

Absorption and transmission: When a photon of light hits a molecule of gas or a particle in the atmosphere, there are three possibilities: 1) it can be absorbed (the energy is converted to heat), 2) it can be reflected (it continues on but in a different direction), 3) or it can be transmitted. These processes determine our ability to see distant objects (such as the mountains around Los Angeles and Irvine) and the colors in the sky (such as blue...

why Lmax shifts towards higher wavelengths when you go from
ethylene to b-carotene?
Figure 1. violet blue green yellow orange red purple 500 800 nm The greater the degree of conjugation of chromophores the greater the chance that the absorption of light will occur at higher wavelengths.

Pre lab
Introduction Your instructor has prepared an extract of chloroplast pigments from fresh green grass or fresh spinach. A blender was used to rupture the cells, and the pigments were then extracted with acetone, an organic solvent. Work- ing with one other student, begin this exercise by separating the pigments extracted using paper chromatography. To do this, you will apply the pig- ment extract to a cylinder of chromatographic paper. You will then place the ylinder in a jar...

please answer all that you can 1. You have genetically engineered green fluorescent protein (GFP) containing a KDEL sequence (GFP-KDEL). When GFP-KDEL is expressed in normal human fibroblasts and examined using fluorescence microscopy, the fluorescence appears diffuse across the cytoplasm. How would you explain this observations given that KDEL is supposed to be an ER-specific sorting sequence? A. This engineered GFP would not have a hydrophobic signal sequence to get it into the RER in the first place. B. The...
