During a race‚ there is an inherent increase in energy requirements and these requirements are maintained by the many biochemical events happening within the body. This essay explores the metabolic processes that occur at the start of the race‚ 5 minutes into the race and 45 minutes into the race in terms of mobilization‚ biochemical pathways used for degradation of molecules and comparing the yield of ATP of the two types of fuels involved‚ namely carbohydrates and lipids. Carbohydrates‚ which have

Glycolysis: Glyco- sugar‚ lysis- burst/break - the process in which a glucose molecule is split into two pyruvic acids (c-c-c). It is the first step of cellular respiration‚ it occurs in the cytosol of the cell and is anaerobic. Glycolysis requires 2 ATP‚ however the splitting of the glucose molecule produces 4 ATP therefore a positive net of 2 ATP. Cellular respiration is an exothermic reaction‚ therefore following glycolysis enzymes and coenzymes will act as

“Respiration” and “Photosynthesis” All life depends on two chemical reactions “Respiration” and “Photosynthesis”. These two processes are quite crucial because they are a source to nearly all life on Earth. Both of these processes are quite similar yet differentiate vastly. In this essay I’ll be comparing and contrasting “Photosynthesis” and “Respiration”. I’ll start by discussing what actually happens

The breakdown of CP releases energy‚ which catalyzes a reaction to produce ATP. The production of more ATP allows movement of the muscle to continue. Lactic acid is a product of glycolysis created by the breaking down of pyruvate. Lactic acid is then disassociated to produce lactate. When lactic acid (C3H6O3) releases a hydrogen ion (H+)‚ the remaining compound binds to a sodium ion (Na+) or a potassium ion (K+) to form a salt. It

• Glycolysis produces 2 ATP molecules. • Citric acid cycle produces the generation of ATP and also releases the chemical carbon dioxide. • ETC produces water when the electrons combine with water. What is the formula for photosynthesis? • The formula for

biochemical pathways to metabolize glucose due to the range of different environments glucose metabolism is needed to occur in. With a low oxygen concentration‚ it isn’t beneficial to have an oxygen-only glycolysis pathway. With no oxygen at all‚ a similar problem can occur. Without varied methods for glycolysis to occur‚ there would be an inability to produce energy or ATP for the cells. References Methyl red. (2014‚ March 16). Retrieved March 21‚ 2014‚ from http://en

When the muscle contracts the sarcomere gets smaller and the area between myosin filaments. What are the net products of glycolysis? ATP‚ NADH‚ Pyruvic Acid What are the net products of cellular respiration? CO2‚ ATP‚ and H2O (select the best answer that contains these. Some answers might contain two of these and then something from the Calvin Cycle) What is the relationship

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 four

Cellular respiration is the metabolic process that releases stored energy from the bonds of organic molecules‚ mainly glucose. There are three stages: 1) Glycolysis 2) Krebs Cycle (Citric Acid Cycle) 3) Electron Transport Chain What is the role of glycolysis? Include the reactants and the products. Where does it occur? Glycolysis splits the glucose molecule into two pyruvic acid molecules. The Reactants going into the process are Glucose‚ NAD+ (and ATP to start the reaction). The products
