occurs only in "green algae" and in the plants.Carotenoids are usually red‚ orange‚ or yellow pigments‚ and include the familiar compound carotene‚ which gives carrots their color. These compounds are composed of two small six-carbon rings connected by a "chain" of carbon atoms. As a result‚ they do not dissolve in water‚ and must be attached to membranes within the cell. Carotenoids cannot transfer sunlight energy directly to the photosynthetic pathway‚ but must pass their absorbed energy to chlorophyll

means more material to produce carbohydrates‚ thereby‚ leading to the plants growing better. 6. Over the past decades‚ the CO2 concentration in the atmosphere has increased. Predict the effect of increasing carbon dioxide concentrations on photorespiration. The effect of increasing carbon dioxide concentrations on photorespiration would be that photorespiration rates should decrease as photorespiration involves rubisco reacting with O2 instead of CO2. Since CO2 is increasing‚ it would make it more

synthesis of the non-essential amino acids‚ amino acid remodeling‚ and conversion of non-amino acid carbon skeletons into amino acids and other derivatives that contain nitrogen. However‚ the liver is the major site of nitrogen metabolism in the body. In times of dietary surplus‚ the potentially toxic nitrogen of amino acids is eliminated via transaminations‚ deamination‚ and urea formation; the carbon skeletons are generally conserved as carbohydrate‚ via gluconeogenesis‚ or as fatty acid via fatty

molecules from inorganic molecules using the energy of light. Producers are when plants make their own organic molecules. A redox reaction is oxidation and reduction. Photosynthesis takes water and carbon dioxide to make glucose and oxygen. Cellular respiration takes glucose and oxygen to make water and carbon dioxide. ● Chloroplasts have an outer and inner membrane. There is intermembrane space and thylakoid space. There is stroma and grana and thylakoid. Chloroplasts are found in mesophyll cells.

Lesson 5/ Key Questions: 18. In the morning‚ when you wake up‚ before you eat‚ go for a walk ‚ swim‚ something for around 3-10 minutes. It will help get your metabolism started and work better through out the day. I would suggest cutting those 2 beers a night into one‚ or maybe 2 every other day‚ or 2 a week. I would eat something like oatmeal in the morning‚ or simple toast with eggs and HAM. Bacon is high in fat and calories. And always get fruit. And Change up your lunch. Make a sandwich. or

PLASTIDS Plastids are large cytoplasmic organelles. Plastids are major organelles found in the cells of plants and algae. Plastids are the site of manufacture and storage of important chemical compounds used by the cell. Plastids often contain pigments used in photosynthesis‚ and the types of pigments present can change or determine the cell’s colour. The term plastid was derived from the Greek word plastikas meaning formed or moulded. This term was coined by Schimper in 1885. In plants

This process takes place in the thylakoid of the chloroplast. Once fired the calvin cycle starts‚ which is the dark reaction. The calvin cycle has three steps the first of which being carbon fixation‚ that is catalyzed by the enzyme rubisco. The second being reduction and the third being regeneration of the carbon dioxide acceptor or the creation of ribulose bisphosphate. This dark reaction takes place in the stroma of the chloroplast. Whereas in cellular respiration there four main parts. The

photosynthetic organisms‚ NADPH is produced by ferredoxin-NADP+ reductase in the last step of the electron chain of the light reactions of photosynthesis. It is used as reducing power for the biosynthetic reactions in the Calvin cycle to assimilate carbon dioxide. Synthesis The oxidative phase of the pentose phosphate pathway is a major source of NADPH in cells‚[1] and in cells without mitochondria‚ it is the only source. However there are several other lesser-known mechanisms of generating NADPH
