Each carrier in the chain has a slightly lower energy level than the previous, so the remaining energy is used to combine Adenosine Di-phosphate with an inorganic phosphate molecule to make ATP cellular energy. Consequently, this ATP along with reduced NAPD co-enzyme are utilised in the light-independent reaction or Calvin Cycle to reduce CO2 and other carbon containing compound such as Glycerate-3-phosphate and triose phosphate into essential organic compounds such as glucose. The overall photosynthetic equation is 6CO2 + 6H2O C6H12O6 + 6O2. For photosynthesis to occur, oak trees require a plentiful supply of water and carbon dioxide -Water Transport and Root pressure and salts -CO2 stomata Because glucose cannot always be used up as
Prelaboratory preparation: Read pages 1 – 30 and 45 – 54 of the lab text. You may disregard the microscale distillation procedures of TECH 0704. Answer in your laboratory notebook the Safety Quiz on pages 11 – 12 and the Prelab Questions 1, 2a, 2b, 3 -5, pp. 67 - 68. EXPERIMENT: TECH 0704, Distillation, macroscale technique only, simple and fractional: Substitute a mixture of 25 mL ethanol and 25 mL water for the toluene/cyclohexane mixture.
Inorganic ions are charged particles that do not contain carbon atoms bonded together. While organisms are mainly built from carbon-containing molecules, their functions rely on inorganic ions such as nitrate, hydrogen and calcium. This essay will detail some of the roles of specific ions and describe how animals, plants and bacteria use them. Productivity in an ecosystem in the soil is limited in part by the availability of fixed nitrogen in the soil. Nitrogen fixing bacteria in the roots of leguminous plants reduce atmospheric nitrogen to ammonium using ATP and reduced NAD.
aOrganic compounds as Fuels Intro – chemistry involved with the diff. and same of diesel and corn biodiesel./used “The fuel of our future is going to come from fruit like that sumac out by the road, or from apples, weeds, sawdust almost anything. There is fuel in every bit of vegetable matter that can be fermented.” – Henry Ford (Winn. 2002) Those words, in which capture the excitement and potential surrounding biofuels today, were spoken in 1925 by the one and only Henry Ford. Nearly a century ago from today, the ford Model-T (collectively known as Tin Lizzie) was designed and manufactured to run on either petrol or a corn-based fuel called ethanol.
* C4 Plants are named because they preface the Calvin cycle with an alternate mode of carbon fixation that forms a four-carbon compound as its first product. Several thousand species in at least 19 plant families use the C4 pathway. Among the C4 plants important to agriculture are sugarcane and corn, also with members of the grass family. In C4 plants there are two distinct types of photosynthetic cells bundle sheaths and mesophyll
For this experiment we will be using cups of: metal, ceramic, plastic, and Styrofoam for our calorimeters. Our insulating materials will include: Styrofoam peanuts, paper towels, cloth towels, aluminum foil, or sea sand. With these materials, we will construct an insulated Dixie cup. The specific heats for the calorimeters follow: Metal: Pending Ceramic: 1063 J/kg C Plastic: 1.41 J/kg C Styrofoam: 1.3 J/kg C The lower the specific heat the less it takes to increase or decrease the temperature. I’m going to infer that Styrofoam will make the better calorimeter.
According to Hopkins (2006), photosynthesis is the process by which green plants and certain organisms transform itself from light energy into chemical energy. As a straight forward chemical reaction in which carbon dioxide comes from the air, along with the midair and water from the soil, photosynthesis conglomerates to produce what is known as carbohydrate (p. 6). Solar Energy produced by photosynthesis, stores itself in a chemical bond of a carbohydrate molecule. Sugar known as glucose is then formed which becomes convenient both by way of energy to be stored for later use in tissues or by way of carbon to be used for cells (p.7). Hopkins, w. G. (2006).
This is the molecule which makes photosynthesis possible, by passing its energized electrons on to molecules which will manufacture sugars. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll "a". A second kind of chlorophyll is chlorophyll "b", which occurs only in “green algae” and in the plants.

For instance, I learned how pigments absorbed strongly move slowly and pigments absorbed weakly move the fastest.
Photosynthesis is the process when plants and some bacteria use the sun lights energy to produce glucose from carbon dioxide and water. carbon dioxide + water- sunlight- glucose + oxygen Energy in the form of light is the definition of electromagnetic energy. Any visible light like light bulbs, electromagnetic energy can take the form of it. The energy is being absorbed to break bonds making the process endothermic. When energy is being released making new bonds formed is called the exothermic process.
WEEK 4 - CARBOHYDRATES Carbohydrates or saccharides: saccharo is Greek for ―sugar‖ Carbohydrates are important macromolecules that consist of carbon, hydrogen, and oxygen in a 1:2:1 ratio (can be written as Cn(H2O)n). Carbohydrates are organic compounds organized in the form of aldehydes or ketones with multiple hydroxyl groups coming off the carbon chain. Carbohydrates are the most abundant organic compounds in living organisms and account for one of the four major bimolecular classes including proteins, lipids, and nucleic acids. They originate as products from carbon dioxide and water by photosynthesis: nCO2 + nH2O (+ reducing agents and energy from photon [sunlight]) → ADP + CnH2nOn + nO2 ADP (Adenosine diphosphate) is a product that can be synthesized to form ATP (Adenosine-5'-triphosphate), a form of chemical energy used in cells which acts as a fuel of metabolism in plants and animals through aerobic cellular respiration. CnH2nOn + nO2 + ADP + Phosphate (+ oxidizing agent and energy from photon [through electrochemical gradient]) → ATP + nCO2 + nH2O Function Carbohydrates play a variety of extensive roles in all forms of life: Carbohydrates are initially synthesized in plants from a complex series of reactions involving photosynthesis.
