Case 1: Hereditary fructose intolerance Enzymes are proteins that increase the rate of chemical activity. Their three dimensional structure determines their function‚ and is made of chains of amino acids that have folded into a specific shape with a unique property. Enzymes lower the activation energy needed for a chemical reaction‚ therefore speeding up the process. Multiple enzymes work together in metabolic pathways‚ taking a product (end result) of one metabolic reaction as a substrate (substance

Intolerance Metabolism is the process of cellular respiration. It involves three steps‚ 1) glycolysis‚ 2) the citric acid or Krebs cycle and 3) electron transport system. The glycolytic pathway or glycolysis is a metabolic process that leads to the formation of the energy source adenosine triphosphate (ATP) in the body. ATP is essential to the cell and the cellular processes used by the cell. The first step‚ glycolysis is the process by which each molecule of glucose is converted to two pyruvate molecules

oxygen levels tend to decrease in light deficient environments. Due to limited oxygen‚ citrate concentrations found in the citric acid cycle are high and affects the activity of the enzyme phosphofructokinase‚ which is found in the early stages of glycolysis and catalyses the conversion of fructose 6-phosphate to fructose 1‚6-bisphosphate‚ by slowing down its function and therefore slowing down cellular respiration (Russell‚ Hertz‚ McMillan‚ Fenton‚ Addy‚ Maxwell‚ Haffie‚ MIlsom 2014).

* Pyranose – ring structure that glucose and many other 6-carbon sugars are capable of forming; it is in either an alpha or beta configuration. * Breakdown of ATP to ADP or of ADP to AMP releases approximately 7 kcal/mol of energy. * Glycolysis: takes place in the cytoplasm; it uses 1 glucose and makes 2 pyruvate; starts with 2 NAD+

PET 3351 Exercise Physiology Second Exam Review (Fall 2012) Chapter IV: The Physiological Basis of Muscular Strength and Flexibility 1. Strength is operationally defined as the maximal force that can be exerted in a single effort. Using this definition‚ strength should be assessed using one repetition maximum (1 RM)‚ though we often estimate strength using tests that may involve multiple repetitions. 2. In strength training and rehabilitation‚ emphasis should be given to both the concentric

Once the conversion is finished the product can enter the glycolysis cycle to from ATP or energy used for the body. “In normal cellular conditions‚ the primary enzymatic activity of aldolase B is to cleave fructose diphosphate (FDP).” (Roth‚ 2012) A5.

HOW MUSCLES GET THE ENERGY THEY NEED TO WORK 1) Muscle needs energy to contract and as stated previously the ‘universal energy currency’ of living systems is ATP (adenosine triphosphate). This is largely produced within mitochondria‚ organelles which are often referred to as the ‘powerhouse’ of the cell. The ATP that results is used to provide the power for the muscle fibres to contract. Contraction itself (i.e. actual shortening movement) occurs when a bond is broken between ATP and one of its
