Benjamin Tiger1/16/12 Cellular Respiration Questions 1. Aerobic pathways require oxygen‚ while anaerobic pathways don’t. Anaerobic pathways only require the process of glycolysis to produce energy. Anaerobic pathways are found outside the mitochondria within the cytoplasm of the cell‚ with a low efficiency of 4%. These pathways require glucose‚ ATP‚ adolase‚ fructokinase‚ dehydrogenase‚ and NAD+. Out of one glucose molecule‚ major products include two net ATP‚ two NADH‚ and two pyruvate

Assignment 1 – PAPER #1; PHOTOSYNTHESIS AND CELLULAR RESPIRATION Name: Melvin G. Abramson SCI 115 – Essentials of Biology Professor: Casey Bethel Date: May 1st‚ 2012 Photosynthesis is the progression of translating light energy to chemical energy and storing it in the acquaintance of sugar. This process occurs in plants and some algae. Photosynthesis takes place in the chloroplasts‚ distinctively using chlorophyll‚ the green pigment implicated in photosynthesis

OF INVERTASE FROM YEAST AND EFFECT OF pH ON ENZYMATIC ACTIVITY Jenelle C. Faustino‚ John Gambit B. Garcia‚ Fatima S. Jusay‚ Oliver Alexander B. Lao and Eunice L. Licudine Group 4 2 E Medical Technology Biochemistry Laboratory ABSTRACT Enzymes are substances that are produced by living organisms and act as catalysts in order to speed up or chance a chemical reaction without changing itself at the end of the reaction. Invertase was extracted first from baker’s yeast. Determination of

Yeast and Sugar - The Chemistry must be right Jansen‚ C. Gymnasium Felisenum‚ The Netherlands 14-04-2010 Summary Yeast can metabolize sugar in two ways‚ aerobically‚ with the aid of oxygen‚ or anaerobically‚ without oxygen. In this experiment yeast ferment sugars anaerobically. When yeast ferments the sugars anaerobically‚ however‚ CO2 production will cause a change in the weight of the sugar/yeast-solution. This raises a further question: What is the effect of different kinds of sugars

Chemistry Lab Report (Design) Factors affecting Rates of a Reaction (Kinetics) KINETICS DESIGN LAB Research Question: Does the concentration of Potassium Iodide (KI) affect the rate of its reaction with hydrogen peroxide (H2O2) (of a fixed concentration)? Introduction: There are several factors that affect the rate of a reaction. Some of them being Pressure (if the reactants are Gases)‚ Temperature‚ Presence of a Catalyst‚ Surface Area of the reactant‚ and Concentration. According to

Title: Factors affecting reaction ratesProcedure A: Effect of ConcentrationAim: To investigate how the concentration of a reactant affects the rate of reaction. Hypothesis: The more concentrated the reactant‚ the faster the rate of reaction. Materials: 2M hydrochloric acid solution‚ magnesium wire‚ distilled water‚ 4 test-tubes‚ measuringcylinder. Procedure:1)10mL 2M hydrochloric acid solution is poured into a test-tube using a measuring cylinder. 2)A 3cm length of magnesium wire is added to

INVESTIGATING FACTORS AFECTING THE RATE OF PHOTOSYNTHESIS! Testing Carbon Dioxide Done by: Krish S. AIM: is to plan and carry out an investigation on factors affecting the rate of photosynthesis. We are doing this by investigating the amount of bubbles produced by waterweed to show the rate of photosynthesis and the effects of carbon dioxide (CO2). HYPOTHESIS: I think that the rate of photosynthesis will increase as the rate of CO2 increases this can be seen by the bubbles produced from

1.Explain the process of Cellular Respiration in order. Where does each step occur in a cell‚ which steps require oxygen‚ and how many ATP are produced in each step? Cellular respiration is the breakdown of glucose in the presence of oxygen to yield ATP. Glycolysis is the first stage in the breakdown of glucose and It occurs in the cell’s cytoplasm. It does not require oxygen (anaerobic). This step also occurs in two steps‚ the energy investment step‚ and the energy yielding step. This process yields

April 25‚ 2013 Some Factors that Affect the Rate of a Reaction BACKGROUND: Chemical reactions occur at different rates. In this experiment I will consider some of the key factors that influence the rate of a reaction: * nature of reactants - particle size * temperature * catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the faster the rate of the reaction
