This lab was completed to determine the rate in which fermentation occurs in different sugars and to compare the rate of cellular respiration in germinating and non-germinating soybeans. Fermentation breaks down sugars for a source of energy. Cellular respiration is the process used by cells to produce energy from nutrients. This process allows sugars and foods to be broke down in order to obtain energy from adenosine triphosphate (ATP). Cellular respiration is vital for survival of cells. Oxygen

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

Cellular respiration: one of the most significant processes known to life today. Cellular respiration is indeed a lengthy process‚ especially just to make ATP (energy)‚ and it all starts with a glucose. The first process to cellular respiration is glycolysis‚ which can be literally translated to the breaking of glucose. To note‚ glycolysis takes place in the cytoplasm of the cell. There are two parts to glycolysis: the “investment” phase and the “harvest” phase. With the aid of two ATP‚ the first

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 is defined as a complex process in which food molecules are broken down to harvest chemical energy which is then stored in the chemical bonds of adenosine triphosphate (ATP). It is usually decided by the metabolic exercise and the equivalent amount of ATP discharge. As long as the extracellular O2 pressure surpass a demanding value ranging from 3-6 torr‚ studies have proof that cellular oxygen uptake stay permanently autonomous of oxygen tension. When the carbon-hydrogen bonds

Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of

CELLULAR RESPIRATION -is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP)‚ and then release waste products. The reactions involved in respiration are catabolic reactions‚ which break large molecules into smaller ones‚ releasing energy in the process as weak so-called "high-energy" bonds are replaced by stronger bonds in the products. Respiration is one of the key

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
