Sarwal AP Lab 4 Determining the rate of Cellular Respiration Using Germinating and Dry Peas Purpose: To determine the rate of cellular respiration using dry and germinating peas. Introduction: In this lab‚ we are investing cellular respiration‚ specifically aerobic cellular respiration. Aerobic cellular respiration is the process by which cells consume oxygen during the oxidation of glucose and produce CO2 as a byproduct. During cellular respiration‚ glucose is split into a 6 carbon sugar‚ G3P

ABSTRACT The effect of co-factor (MgSO₄) and the nature of substrate on the rate of cellular respiration in yeast were determined using two different set-ups. In the first set-up‚ two test tubes were used where one contains 7m and the other with 7 mL 0.2M MgSO₄ and both containing 7mL 10% yeast suspension. Here‚ data shows that the H₂O mixture showed higher amount of CO₂ evolved than MgSO₄. In the second set-up‚ six Smith fermentation tubes were used each containing different 15mL solution (starch

Lab 7 – Cellular Respiration Objectives: • To be able to define cellular respiration and fermentation. • To give the overall balanced equations for aerobic respiration and alcoholic fermentation. • To distinguish between inputs‚ products‚ and efficiency of aerobic respiration and those of fermentation. • Understand the relationship between respiration and photosynthesis. Note: You should perform experiments as described in this handout‚ which are adapted from Starr and

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

- Cellular Respiration Assignment - 1. What two molecules are formed when a phosphate is removed from ATP? There are three phosphate groups in ATP molecule (Adenosine Triphosphate)‚ when removing one phosphate molecule‚ ADP molecule is formed (Adenosine Diphosphate). 2. What is the function of ATP? Describe the molecule. The function of ATP is storing energy within a cell. ATP is adenosine triphosphate‚ C10H16N5O13P3‚ a high energy complex‚ giving the necessary power to push metabolistic

Cellular Respiration and Fermentation: Experimenting With CO2 and Redox Reactions Julius Engel; Section 8 Abstract In this experiment‚ the subjects of study were fermentation‚ mitochondrial respiration‚ and redox reactions. In the first experiment‚ yeast was grown in various carbohydrate solutions at various temperatures. In the second experiment‚ succinate was added to various samples of a mitchondrial suspension‚ DPIP‚ and a buffer. Then after two blanks were used‚ the samples

Cellular Respiration Purpose The purpose of this experiment was to determine the effect of body mass and temperature on the rate of respiration in the mouse. Hypothesis When the temperature is reduced‚ cellular respiration will increase. Measurement Weight the mouse and use soda lime for mouse to perspire. Oxygen was inhaled and carbon dioxide was exhaled. Carbon dioxide was absorbed by soda lime. Rate of respiration was measured in terms of ml of oxygen per min over grams. General

increased consumption of oxygen and nutrients by muscle cells requires more blood supply. The functions of blood include delivering oxygen‚ removing CO2‚ removing heat and delivering nutrients and water. Therefore‚ blood flow is important in cellular respiration‚ which is the process where ATP is produced through the conversion of metabolites‚ also involving the consumption of oxygen and release of CO2 as a waste product. ATP is vital to skeletal muscle contraction‚ since the power stroke is facilitated

Steps to Study Aerobic Cellular Respiration The mitochondrion made ATP How does the mitochondrion make ATP? Glycolysis breaks down a glucose molecule Pyruvate is created via Glycolysis The acetyl CoA is produced from Pyruvate Citric acid comes from acetyl CoA and Oxaloacetate Citric acid was the starting molecule for the Krebs cycle The NADH and the FADH2 were generated by the Krebs cycle Oxidative Phosphorylation involves electron transport chain (ETC) and Chemiosmosis
