Both contain enzymes. G. Chloroplast is different in that it has a thylakoid membrane and thylakoid space. This membrane is similar to the inner membrane of mitochondria in that it is impervious and that a proton gradient is developed between its inner and outer surfaces. Light reactions drive protons into the thylakoid space just as the electron transport system drives protons into the intermembrane space of mitochondria. These photosystems utilize the energy of the sun to split water and capture electrons due to this split and boost their energy so that they can accomplish two things.
Chlorophyll b c. Contains a porphyrin ring that binds magnesium.
Each pigment will absorb light at its own optimal wavelengths. This enzyme is the most abundant protein in nature. Once combined the newly formed 6 carbon breaks into two 3 carbon compounds.
