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

This scientific report will be based on cellular respiration‚ or fermentation. In specific‚ how the type of sugar affects the rate of fermentation. The aim of this experiment was to find which type of sugar was best suited to produce ethanol. In the experiment‚ four different sugars were used‚ they included sucrose‚ glucose‚ lactose and fructose. This research is still relevant today‚ as alcohol is still consumed and is required on a large scale. This makes it crucial to companies to find the best

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

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

Balloon Respiration Lab Introduction/ Background Cellular respiration is a process that releases chemical energy from glucose and other carbon-based molecules to produce ATP when oxygen is present. The formula for cellular respiration is C6H12O6+ 6O2= 6CO2= 6H2O. The process of respiration contains three main parts‚ glycolysis‚ Krebs cycle‚ and the Electron Transport Chain. The process of glycolysis takes place in the cytoplasm and is considered an anaerobic process which splits glucose into two

Cellular respiration‚ which synthesis ATP‚ begins with glycolysis‚ wherein a six-carbon glucose is broken down into two three-carbon molecules called pyruvate. This process requires the input of two ATPs to produce two pyruvates‚ two NADHs‚ and 4 ATPs. The NADHs are synthesised when NAD+‚ delivered by B vitamins‚ become bound to hydrogen and energised electrons1. Following glycolysis is the Krebs cycle and electron transport chain respectively. The Krebs cycle uses the two pyruvates produced in glycolysis

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
