Titration Lab How Much Citric Acid is in Your Soda? PURPOSE To determine the molarity (concentration) of citric acid (H3C6H5O7) in various different citrus flavored sodas. BACKGROUND PRINCIPLES Popular sodas all strive for a somewhat sour (’tart’) flavor and manufacturers utilize acids to impart this taste. While there are a vast variety of different brands of sodas on the market‚ they can be broken into two main categories: dark or clear. This differentiation is not only a simple color

Premium Glycolysis Adenosine triphosphate Cellular respiration
Adenosine Triphosphate Enzymes are proteins and their function is to act as catalysts to speed up certain chemical reactions in the cell that would be slower without them. This process occurs as steps in a cycle with separate reactions in each step. If there is a missing product the step in the cycle will be incomplete and the normal function of the organism cannot be accomplished causing negative effects on the organism. The biological processed of the body would occur much more slowly or possibly

Governor’s University GRT1 Metabolism Enzymes are molecules that are responsible for chemical reactions that occur within the body. They act as catalyst by accelerating metabolic reactions from the digestion of foods to synthesizing deoxyribonucleic acid (DNA). An enzymatic reaction changes substrates‚ the beginning molecule‚ into products. Enzymes are selective for the type of substrate that they will bind to; they have specific shapes that fit into one another like a lock and key as illustrated in

(Wolfe‚ 2000) Importance of Aldolase B Enzyme -Glucose and fructose are the components that make up sugar (sucrose). -In order to make ATP (energy)‚ glucose and fructose need to go through glycolysis and enter the Krebs cycle. -Fructose needs enzymes to break it down further‚ before it can enter the glycolysis process. -Initially‚ fructose is broken down by the enzyme fructokinase into fructose-1-phosphate. -The substrate fructose-1-phosphate (F-1-P) is then further

” (Haldeman-Englert‚ 2011) A4. Substrate The specific substrate acted on by Aldolase B is fructose-1-phosphate (F1P). This then is converted into DHAP and glyceraldehyde. Once the conversion is finished the product can enter the glycolysis cycle to from ATP or energy used for the body. “In normal cellular conditions‚ the primary enzymatic activity of aldolase B is to cleave fructose diphosphate (FDP).” (Roth‚ 2012) A5. Role of Aldolase B Aldolase B is the substance needed to breakdown

March 5‚ 2013 Biology 1111 Term Paper Glycolysis and the Citric Acid Cycle Glycolysis occurs in the cytoplasm outside the mitochondria‚ it is a metabolic pathway that is the breakdown of glucose (C6) and ends with 2 pyruvate (C3) molecules. Energy is invested to activate the glucose‚ 2 ATP are gained‚ and oxidation results in NADH‚ which will be used later for additional ATP production. Glycolysis is divided into (1) the energy-investment step‚ when ATP is used; and (2) the energy-harvesting

through cellular respiration. Cellular respiration is defined as the aerobic harvesting of chemical energy from organic fuel molecules. Cellular respiration occurs in eukaryotic and prokaryotic cells. It has three main stages: glycolysis‚ the citric acid cycle‚ and electron transport. Stage one glycolysis means the “splitting of sugar”. Glycolysis is a six carbon glucose molecule which is then broken in half‚ forming two three carbon molecules. The initial split requires an energy investment of two

anabolism‚ small precursor molecules are assembled into larger organic molecules. This always requires the input of energy. Anabolism is the synthesis of complex molecules from precursors. This includes synthesis of proteins‚ carbohydrates‚ nucleic acids and lipids‚ usually from their building block monomers. Catabolism is the breakdown of complex molecules into smaller precursors from which they are synthesized. It is a reversed process of anabolism. When cells have excess resources such as food
