explain the role of carbon dioxide in photosynthesis. The role of carbon dioxide in photosynthesis is that during the Calvin cycle, CO2 that enters the cell is combined with RuBP. This molecule is extremely unstable and because of that it splits from a 6 carbon molecule to a 2 carbon molecule through series of reactions and with ATP and NADPH produced during the light reaction. This molecule is eventually converted to glucose. Ultimately CO2 used to make this glucose in the Calvin cycle. d. Describe

cellular locations and organelles involved in photosynthesis. The outside of the leaf is covered in a waxy layer that helps prevent water loss called the cuticle. On the underside of the leaf there are small pores called stomata, which take in carbon dioxide to convert into sugar. Inside the leaf, water is transported through tubes called xylem. Photosynthesis occurs in the mesophyll (interior) layer of the leaf. These are the cells that contain chloroplasts, which are the major sites for glucose

equilibrium of incoming and outgoing radiation that makes the Earth habitable. Without this balance, the greenhouse effect sets in. Definition Greenhouse Effect: The warming of the atmosphere due to the increased amounts of greenhouse gases such as carbon dioxide, nitrous oxides and methane. These gases form a blanket over the Earth, trapping the energy or heat from the sun and preventing it from leaving the atmosphere. A greenhouse works in much the same way-Incoming UV radiation easily passes through

both adults and children; this includes calcium, vitamins A, B & D. The history of milk began in the Neolithic age (the new stone age), a time when humans started the transition from hunting and gathering to a more settled way of life. Life Cycle of Milk Supply Chain: Environmental and societal impact of Milk; The dairy industry poses a number of challenges to the health of the environment- * Methane emission- this is release from cows’ during the digestion process either by belching

Ch. 10: Photosynthesis (Ps) • Ps is the process that converts solar energy into chemical energy – Directly or indirectly, Ps nourishes almost the entire living world – Ps occurs in plants, algae, certain other protists, and some prokaryotes • Autotrophs sustain themselves without eating anything derived from other organisms – Autotrophs are the producers of the biosphere, producing organic molecules from CO2 and other inorganic molecules – Almost all plants are photoautotrophs, using the energy

the sun’s energy to make carbohydrate from carbon dioxide and water. This is called photosynthesis. Humans and animals eat the plants and use the carbohydrate as fuel for their bodies. During digestion, the energy-yielding nutrients are broken down to monosaccharides, fatty acids, glycerol, and amino acids. After absorption, enzymes and coenzymes can build more complex compounds. In metabolism they are broken down further into energy (ATP), water and carbon dioxide. A. Metabolic reactions take

process, The Kreb’s Cycle. Before the Kreb’s Cycle, the process of Glycolysis breaks glucose into 2 Pyruvate molecules, which is then oxidized into 2 Acetyl CoA. The two-carbon acetyl part of Acetyl CoA enters the Kreb’s Cycle with help from Coenzyme A, the latter of which is then recycled. The acetyl group combines with a four carbon molecule, marking a six carbon molecule

operational aspects of an organization, i.e. all operations across the activity chain/value chain, which impact the business in either one or all the three dimensions. Carbon impact is not limited within the boundaries of owned operations but in the total activity and value chain, - vendors and consumers. Utilizing life cycle assessment approach can be a useful way to understand the full impacts across the activity/ value chain. On knowing, where the main impacts are, organisation can

Glucose, a six-carbon molecule, is split into 2 three-carbon molecules of PGAL. As oxidation takes place, NAD picks up a hydrogen atom from each molecule to form 2NADH. Phosphorylation takes place again. For each molecule, 2ADP combine with two phosphates to form a total of 4 ATP, and pyruvic acid molecules are formed. A net gain of 2 ATP have been formed. As the pyruvic acid molecules make their way toward the mitochondria, two more molecules of NADH are formed. A carbon atom also breaks

At the start of exercise the body cannot deliver oxygen to the muscles fast enough so it occurs on anaerobic for the couple of minutes. The aerobic system can be split into three sections: * Glycolysis * Krebs cycle * Electron transport chain Glycolysis:
