The main chemical compound cells use for energy is Adenosine triphosphate (ATP) 3. Ribose is a 5-carbon sugar molecule that is part of an ATP molecule. 4. The phosphate groups of ATP are the key to its ability to store and supply energy. 5. ATP releases energy when it breaks bonds between its

Transporting Nutrients Pigments and photosynthesis 1. Distinguish between the strategies used by autotrophs and heterotrophs to obtain free energy for cellular processes. In other words‚ how and in what form does each capture and store that energy? 2. Explain how photosynthesis differs in eukaryotic organisms (with organelles such as chloroplasts) and in prokaryotic organisms (single-celled‚ no organelles). 3. How does a metabolic pathway such as photosynthesis suggest common ancestry? 4

Coupled Reactions ABSTRACT A way to drive a non-spontaneous reaction forward is by coupling it with another reaction that is highly spontaneous‚ resulting to a spontaneous overall reaction. In this study‚ since the extraction of C(s) from CO2(s) is a non-spontaneous process‚ it was coupled with the oxide formation reaction of Mg‚ a reaction with high spontaneity‚ so that the process of the extraction of C(s) would proceed. The reactions and products which were a mix of black and white

Yogurt Fermentation Yogurt is made by lactic acid fermentation. The main (starter) cultures in yogurt are Lactobacillus bulgaricus and Streptococcus thermophilus. The function of the starter cultures is to ferment lactose (milk sugar) to produce lactic acid. The increase in lactic acid decreases pH and causes the milk to clot‚ or form the soft gel that is characteristic of yogurt. The fermentation of lactose also produces the flavor compounds that are characteristic of yogurt. Lactobacillus

“Respiration” and “Photosynthesis” All life depends on two chemical reactions “Respiration” and “Photosynthesis”. These two processes are quite crucial because they are a source to nearly all life on Earth. Both of these processes are quite similar yet differentiate vastly. In this essay I’ll be comparing and contrasting “Photosynthesis” and “Respiration”. I’ll start by discussing what actually happens

From a chemical perspective‚ what is oxygen? Identify its atomic number‚ the group it fits into OXYGEN in the periodic table‚ its chemical formula‚ its melting point‚ boiling point and state at room temperature. Oxygen is highly reactive‚ nonmetal‚ oxidising agent that readily forms oxides‚ it is an element. By mass‚ oxygen is the third-most abundant element after hydrogen and helium. The Atomic Number: 8 Group: The chalcogen group Chemical formula: 02 Melting

2. Describe the steps involved transforming energy from burning glucose to synthesis of ATP. Cellular respiration‚ in the process of ATP synthesis‚ refers collectively to intercellular reactions in which energy-rich molecules are broken down to form ATP‚ using O2 and producing CO2 (2). In most cells‚ ATP is generated from the disassembling of absorbed nutrient molecules in three stages‚ glycolysis: in the cytosol‚ the citric acid cycle: in the mitochondrial matrix and oxidative phosphorylation: at

requires some sort of energy that our body produces. The most important energy molecule in the cell that our body uses is adenosine triphosphate (ATP). ATP is “a high-energy molecule that stores a considerable amount of energy within the chemical bonds that hold the molecule together” (Exercise Physiology: Tennis Physiology). ATP results from energy being produced from either an aerobic system or anaerobic system. The production of ATP can come from systems such as ATP-PC and glycolysis‚ which is

#2 Elodea and Photosynthesis by __________________ Name:_____________________ Class:_____________________ Teacher:_____________________ Date:_____________________ Elodea and Photosynthesis Introduction: Photosynthetic organisms (cyanobacteria) first evolved about 3.5 billion years ago and are the oldest know fossils on Earth. Cyanobacteria live in water‚ can manufacture their own food‚ and are one of the most important groups of bacteria on Earth. The Cyanobacteria have been important

more than one forms of fermentation; yeast fermentation is probably the most common method. This process is used in many everyday products today. Yeast was first discovered in 1676‚ but was used before. It has also led to numerous scientific advances. Yeast expands‚ especially well with a good amount of sugar‚ the more of the amount the greater it expands. Yeast is a single-celled organism‚ a fungus to be more specific. They consume carbohydrates‚ mainly sugars‚ and produce carbon dioxide and ethanol
