Abstract Density functional theory (DFT) calculations have been used to investigate the structural properties‚ dipole moments‚ polarizabilities‚ Gibbs energies‚ hardness‚ electronegativity‚ HOMO/LUMO energies‚ chemical potentials‚ density of states and detonation properties of trans and cis configurations of azocubane. All properties have been obtained using the B3LYP functional and 6-31G(d‚p) basis set. Also‚ IR‚ UV-Vis‚ CD and NMR spectra of the structures were simulated. The volumes of the structures

letter X is most likely? a) fatty acid b) DNA c) PGAL d) an amino acid 3. Which process is represented by equation I? a) photolysis b) carbon fixation c) synthesis d) the dark reaction Photosynthesis and plant structure Photosynthesis is the process of converting light energy to chemical energy and storing it in the carbon-hydrogen bonds of glucose. This process occurs in plants and some algae. Plants need only light energy‚ CO2‚ and H2O to make sugar. The process of photosynthesis

English Ivy‚ C4 Plant‚ and a multicolored plant. Each type of leaf was tested in a sodium bicarbonate solution and a solution of distilled water. It will be shown in the discussion whether the hypothesis made was correct or incorrect. It will be shown in the discussion what could have occurred during the experiment that could have affected the results. Introduction: Photosynthesis can be defined as the process by which green plants‚ and other organisms make carbohydrates from carbon dioxide and water

6. Many organisms can withstand periods of oxygen debt (anaerobic conditions). Yeast undergoing oxygen debt converts pyruvic acid to ethanol and carbon dioxide. Animals undergoing oxygen debt convert pyruvic acid to lactic acid. Pyruvic acid is fairly nontoxic in even high concentrations. Both ethanol and lactic acid are toxic in even moderate concentrations. Explain why this conversion occurs

The Inorganic Chemistry of Carbon Inorganic Carbon For more than 200 years‚ chemists have divided compounds into two categories. Those that were isolated from plants or animals were called organic‚ while those extracted from ores and minerals were inorganic. Organic chemistry is often defined as the chemistry of carbon. But this definition would include calcium carbonate (CaCO3) and graphite‚ which more closely resemble inorganic compounds. We will therefore define organic chemistry as the study

The evolution of plants has resulted in increasing levels of complexity‚ from the earliest algal mats‚ through bryophytes‚ lycopods‚ ferns to the complex gymnosperms and angiosperms of today. While the groups which appeared earlier continue to thrive‚ especially in the environments in which they evolved‚ each new grade of organisation has eventually become more "successful" than its predecessors by most measures. Probably an algal scum formed on land 1‚200 million years ago. In the Ordovician period

This causes a fading of carbon pump. 11) Subject: ’Black Box’ plankton found to have huge role in ocean carbon fixation/plankton assignment

NADPH The Oxygen is waste‚ and leaves! So‚ in this stage‚ water comes in. ATP and NAPDH come out‚ as does Oxygen. 2. Light independent stage (Carbon Reduction) Happens in the stroma of the chloroplast. It’s the Calvin Cycle At the start of the cycle‚ there’s a 5 Carbon molecule RuBP A CO2 molecule enters and attaches to it‚ making a 6 Carbon molecule Rubisco is the enzyme that makes this happen.

Microbial metabolism is the means by which a microbe obtains the energy and nutrients (e.g. carbon) it needs to live and reproduce. Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic characteristics. The specific metabolic properties of a microbe are the major factors in determining that microbe’s ecological niche‚ and often allow for that microbe to be useful in industrial processes or responsible for biogeochemical

sugars (glucose) are produced. In plants‚ photosynthesis occurs only in cells with chloroplasts. Water (H2O)‚ carbon dioxide (CO2) and light energy are required. The light energy is absorbed by the green pigment‚ chlorophyll‚ and is converted into chemical energy‚ which causes the water drawn from the soil to split into molecules of hydrogen and oxygen. The hydrogen combines with the carbon dioxide in the air‚ forming the sugar. Oxygen from the water molecules is given off in the process. However‚
