The effect of light quantity on photosynthesis of green land plants Introduction Photosynthesis is the process of converting light energy into chemical energy (Hoober 1984). Pigments within chloroplasts‚ primarily chlorophyll‚ absorb the incoming solar energy which excites their electrons (Hoober 1984). These pigments exist in photosystems in the thylakoid membrane of the chloroplast (Ladiges et al.2010). As the electrons return to ground level‚ they are captured by the electron acceptor in the

display similar characteristics. In this experiment‚ identification of the unknown ketone is accomplished through thin layer chromatography‚ melting point‚ and 1H-NMR spectroscopy. The unknown ketone is from a homologous series of methyl ketones. CH3CO (CH2) nCH3 The first step in the lab is the preparation of the solvent used in the developing chamber for thin layer chromatography. The solvent used is a 3:1 mixture of toluene and petroleum. After the developing chamber is prepared‚ it is essential to

Relationship and biodiversity Introduction Botana curus is a valuable plant because it produces Curol‚ a compound used for treating certain kinds of cancer. Curol cannot be produced in the laboratory. Botana Curus grows very slowly and is on the endangered species list‚ so its ability to provide Curol in large quantities is limited. Species that are more closely related to Botana curus are more likely to produce the important substance Curol. Three similar plant species that are plentiful (X

Organization of pigments in photosystems. a) What is the concept of a photosystem? b) Photosystems are organized into two subcomponents: * antenna complex: Lots of pigments (A‚ B‚ and carotenoids) Pigments along with some proteins that organize some pigments about 200 found‚ scaffold proteins * reaction center complex A pair of chlorophyll A are found

far back as the 1300s. Food color additives are dyes‚ pigments or substances that impart color when applied to a food‚ drug‚ cosmetic‚ or the human body. The Food and Drug Administration (FDA) is responsible for regulating all color additives used in the United States. All color additives permitted for use in foods are classified as "exempt from certification" or "certifiable". Color additives that are exempt from certification include pigments that are derived from natural sources such as vegetables

Premium Pigment
The most common pigment is chlorophyll which gives plants their green colour. Chlorophyll helps to absorb energy from sunlight. If chloroplasts didn’t exist‚ plants wouldn’t be able to survive because photosynthesis is needed for plant survival and because plants provide

Lesson Learning Outcomes Upon completion of this lecture‚ students should be able to: understand the structures and properties of amino acids know the groups of amino acid What are amino acids? Amino acids are molecules that when combined with each other proteins. Amino acids contain a central tetrahedral carbon atom (α-carbon) amine group‚ carboxyl group‚ R-side chain The R-side chain determines the different amino acids There are 20 common amino acids Amino acids can join via peptide
