describe and explain the steps in the light dependent reaction of photosynthesis - correct answer 1. photoionisation: light reaches chlorophyll in PSII, which is absorbed by an electron, which becomes excited and moves to a higher energy level. 2. the electron passes to a carrier protein in the thylakoid membrane, and is passed down a series of carrier molecules called an electron transfer chain. 3. as the electron moves down, energy is lost from the electron and is released as ATP. 4. the lo...

Carotenoids - correct answer lipid derivatives, produce pigments in plants and animals , An accessory pigment, either yellow or orange, in the chloroplasts of plants. By absorbing wavelengths of light that chlorophyll cannot, carotenoids broaden the spectrum of colors that can drive photosynthesis. Porphyrins - correct answer lipid derivatives, a group of light-sensitive, pigmented, ringed chemical structures that are required for the synthesis of hemoglobin. Complexed with metals such as iro...

What is the proteome of the cell? correct answer: the full complex of proteins that can be produced using genetic material and post translational modifications What are some example of post translational modifications? correct answer: phosphorylation (signalling) GPI anchor (PM proteins) O-glycans (nuclear and cytosolic proteins) polyubiquitination (can induce protein degredation) How can you watch the purification of recombinant poly-His tagged GFP? correct answer: use Ni2+ immobili...
