Anabolism - Photosynthesis
Anabolism is the molecular level chemical processes associated with the preparation of compounds from simple to complex occurring within a cell. Examples of the most famous Anabolism is the process of photosynthesis. The process of photosynthesis takes place in two stages, the light reactions and dark reactions. This process occurs in the plastids grains. Most leaves have a green plastids so called chloroplasts. The following are the organelles called chloroplasts. This organelle has sections: Grana thylakoids stroma thylakoid space between the membrane areas mentioned above that photosynthesis occurs in two stages, the light reactions and dark reactions. Light reaction occurs in the description section No. 1 while the dark reaction occurs at number 4. Photosystem is a unit that is capable of capturing sunlight energy that consists of chlorophyll a, antenna complexes, and electron acceptors. [7] In the chloroplast, there are several kinds of chlorophyll and other pigments, such as chlorophyll a, light green, dark green chlorophyll b, and carotene are yellow to orange. [7] The pigments cluster in the thylakoid membrane and form the pigment that plays an important role in photosynthesis. [11] Chlorophyll a is located in the central part of the reaction. [12] Chlorophyll is instrumental in delivering high-energy bogota electrons to the primary electron acceptor. [12] The electrons are then entered into the system the electron cycle. [12] The electrons are released chlorophyll a have high energy because the energy gain of the light emanating from the pigment molecules known as antenna complex. [11] In plants, photosystem bogota can be divided bogota into two, namely photosystem I and photosystem II. [11] In photosystem I is the absorption of light energy by chlorophyll a made sensitive to light with a wavelength of 700 nm that is also called the P700 chlorophyll a. [13] The energy transferred from the complex antenna P700. [13] In photosystem II absorption of light energy by chlorophyll a do-sensitive wavelength of 680 nm so-called P680. [14] oxidized P680 is a more powerful oxidizing agent than P700. [14] With a larger redox potential, negative electrons would be enough to obtain electrons from water molecules. [7] Consider the following picture the light reaction is a reaction involving bogota solar energy while the dark reaction (Calvin-Benson Cycle) can occur without the presence of sunlight. From the figure it can be seen that: light and dark reactions bogota related, relation is light reactions provide the energy for the reaction to the dark reaction. Prepared by the reaction energy in the form of ATP and NADPH bright. ATP was obtained from the photon energy from the sun and the H + on the NADPH derived from the breakdown of water. Besides solving the water also produces oxygen to be released into the environment. In the dark the reaction of sugar produced by utilizing CO2 environment.

[7] Photosynthesis in plants Plants bogota are autotrophs. [4] Autotrophs means to synthesize food directly from inorganic compounds. [4] Plants use carbon dioxide and water to produce sugar and oxygen necessary as food. The energy for this process comes from photosynthesis. Envirom
