an enzyme called fructokinase is responsible for splitting fructose into fructose 1-phosphate, a six-carbon fructose. Another enzyme called aldolase B splits fructose 1-phosphate into two three-carbon molecules, dihydroxyacetone phosphate (DHAP) and glyceraldehyde. These products are then able to enter the glycolysis pathway to be converted to pyruvate, which is essential for the citric acid cycle and the production of adenosine triphosphate (ATP) for cellular energy. A2. Deficiency in Aldolase

What is the role of the citric acid cycle? Include the reactants and the products. Where does it occur? Coenzyme A is removed when the two-carbon compound is attached to a four-carbon compound producing a six-carbon compound (citrate). Each citrate molecule undergoes a series of reactions that removes 2 carbon atoms which are released as CO2. In addition, 3 NADH, 1 ATP, and 1 FADH2 are produced. In addition, the four-carbon compound that began the cycle is regenerated ("Cellular Respiration"

hundreds of other easily recognized species. The carbon, phosphorus, and nitrogen cycles are each apparent and active in the park. Carbon is part of every living thing, and cycles through living organisms, air, water, and will fixate in the ground; coal is carbon stored in a solid mineral state. Carbon is stored in several places; it is found in the atmosphere, the biosphere, and the oceans in both living (fish and plants) and non-living (dissolved carbon and carcasses) distributions. It is stored in

The tricarboxylic acid cycle is a series of metabolic reactions, involving both catabolism and anabolism in its cycle, to metabolise glucose or fatty acids or amino acids. Aerobic glycolysis leads to the TCA cycle producing two pyruvate, which are to be used as an Acetyl COA supply. The main functions of the TCA cycle are to improve ability of respiration to produce energy in the form of NADH carrier co enzymes which pump electrons into the electron transport chain which then makes ATP using the

Earth is home to an abundance of astonishing, complex forms of life. We humans are constantly learning more and more about this planet. Earth has been humanity’s mysterious home since the origin of our species, but in the last century or so there has been an alarming trend taking place. We have experienced the Earth’s temperature rising. Global warming is the name of the phenomenon that has taken place over approximately the past 133 years, and according to NASA, it is an un-debated fact that the

eukaryotic and prokaryotic cells and has three main stages which include glycolysis, the citric acid cycle, and electron transport. • What is the role of glycolysis? Include the reactants and the products. Where does it occur? Glycolysis actually means splitting sugars and occurs in the cytoplasm. Glucose which is a six carbon sugar is split into two molecules of a three carbon sugar. In the process, two molecules of ATP, two molecules of pyruvic acid and two high energy electron

between glucose to coenzymes and then to oxygen. The three stagesare: glycolysis, citric acid cycle, and electron transport. • What is the role of glycolysis? Include the reactants and the products. Where does it occur? Glycolysis is the sugar splitting process where the molecule is split in half outside of the mitochondria. The molecule NAD+ picks up electrons and hydrogen atoms from the carbon molecule and become NADH. ATP is produced from the process, as well as pyruvic acid. Glycolysis

(ATP). Although carbohydrates,fats, and proteins can all be processed and consumed as reactant, it is the preferred method ofpyruvate breakdown in glycolysis and requires that pyruvate enter the mitochondrion in order to be fully oxidized by the Krebs cycle. The product of this process is energy in the form of ATP (Adenosine triphosphate), by substrate-level phosphorylation, NADH and FADH2 Simplified reaction: | C6H12O6 (aq) + 6 O2 (g) → 6 CO2 (g) + 6 H2O (l) | | ΔG = -2880 kJ per mole of C6H12O6

ECOSYSTEMS: TROPICAL RAINFORESTS Kyle Faulkner AIU Online Environmental Science Laura Stepp March 25, 2012 Abstract This article focuses on the rainforest’s and its structure, both biotic and abiotic and the the cycles that gives us the ability to live on this Earth. There are a several different types of biomes that cover the vast surface of our planet, but one in particular is very important. The Tropical Rainforest can be described as a forest of tall trees that is located in areas

“Oxygen-Carbon Dioxide Cycle” The organisms in an ecosystem need each other. Plant are called producers for they manufacture their own food with the aid of sunlight, air and water. In the manufacture of their food, they produce a by-product which is oxygen and an end-product which is the starch or sugar that they use. This enables them to live by themselves, without eating other organisms. That is why they are referred to as producers. On other hand, other organisms in the ecosystem eat the
