Expert Solution

Ans.

Plants use the photosynthesis reaction to make their food.
They use energy of light from light dependent reactions to produce two key ingrediants necessary for next stage of photosynthesis ; ATP and NADPH.
In plants, choloroplast (the thylakoid membrane of organelles) is the site of this light reaction.
Photosystems, which are made up of proteins and pigments (light absorbing molecules) complexes, are suitable to harvest light and are important in light reactions.
Two types of photosystems are mainly found - photosystem 1 and photosystem 2.
Many pigments are found in these photosystems which capture light energy, as are found a special pair of chlorophyll molecules.
P700 is the special pair of photosystem 1 where as special pair of photosystem 2 is known as P680.
Captured energy flows from P680 (photosystem 2) to P700 (photosystem 1).
Chlorophyll a and chlorophyll b are photosynthetic pigments found in chloroplast and help pass energy inside to the main reaction centre.
Flow of energy occurs from chlorophyll a to chlorophyll b.
This transfer of energy from chlorophyll molecules pave the way for the electron to rech electron transport chain (ETC).

Photosynthesis 1. Know the photosynthesis equation 2. Understand what pigments are in plants and their functions; including why having multiple types of pigments rather than just chlorophyll is beneficial. 3. Basic understanding of color: when we see a color, what are our eyes really detecting? In other words, why do we see plants as green? What does that tell us about the wavelengths that the chlorophylls absorb? 4. Have a good understanding of the virtual chromatography lab; not necessarily the...

How does C4 photosynthesis differ from C3 photosynthesis? In C4 photosynthesis, CO2 is captured in the mesophyll and transferred to the bundle sheath cell where photosynthesis occurs CO2 capture and photosynthesis occur simultaneously at night in C4 plants while in C3 plants they occur simultaneously in the day C4 plants use more water for photosynthesis than C3 plants In C4 photosynthesis, CO2 is captured in the bundle sheath cells and transferred to the mesophyll cells where photosynthesis occurs.

A tetrahedron is to be moved along a trajectory such that at the end of the trajectory (t=1) it is rotated 45 deg. about the vector [1,1,1] (positive rotation) and the centroid of the tetrahedron is translated to [x,y,z]=[2.525, 1.675, 1.575]. Calculate the transformation matrix at t=.50 using linear interpolation for the translational and rotational part of the transformation matrix. (Hint: for the rotational part interpolate the quaternion representation of the rotational part). A tetrahedron originally has coordinates at t=0:...
