In the cardiac muscle, energy production from available substrates is obtained by step-by-step, enzymatically controlled substrate metabolism and mitochondrial oxidative phosphorylation, in which the energy content of fuels is transferred to the high-energy phosphate bonds of adenosine triphosphate (ATP). In turn, the energy necessary to produce contractile work from hydrolysis of ATP is produced primarily from the metabolism of carbohydrates and FFAs glucose metabolism is an important source of

1. Select one anaerobic and one aerobic adaptation and discuss their significance in terms of what your client will feel or experience. An Acute response to Aerobic Endurance Training: Metabolic Response: Increase in Oxygen Consumption. Endurance sports rely primarily on oxidative (aerobic) metabolism for energy supply. When the exerciser or the athlete

will get higher until it dies. 2. Explain a process of metabolism in the form a fairy tale or comic-book type story using information provided in your lecture slides. You can choose prokaryotic fermentation, eukaryotic fermentation, or respiration (Krebs & Electron Transport). Do not go overboard with literary tools and adjectives. You cannot use glycolysis. Sam’s Example: Once upon a in the cell cytoplasm, there was a six carbon sugar called glucose and with the input of two ATP

Metabolism . Metabolism refers to the chemical reactions that take place in living organisms. There are two categories for metabolism: ---Catobolism: break down of matter ---Anabolism: build up matter (proteins, nucleic acids) Enzymes are the proteins that breakdown matter in catabolism. (Wikipedia/ metabolism, 2013) How do enzymes work? An enzymes job is to lower the activation energy for a reaction in order to increase it’s rate. (Wikipedia/

Zayra Mendivil EXS-340 September 29, 2013 William Kuehl Energy Transfer Glycolysis is the metabolic pathway that takes glucose and breaks it down into pyruvate. This anaerobic cycle that can occur in the presence of oxygen or not. It is used to release high energy compounds of adenosine triphosphate, ATP. Glycolysis takes one glucose and results in two three carbon chains of pyruvate, along with a net total of two ATP released. The Kreb, or Citric Acid, Cycle is series of chemical reactions

Role of Enzymes ¨. Catalysts that help a molecule breakdown faster. ¨. Catalysts speed up or slow down a biochemical reaction by increasing or decreasing the activation energy. Does not change in reaction. ¨. Enzymes bind to a substrate to form the enzyme substrate complex. When bound the enzyme has a specific job it was designed to do. Once the job is done, the substrate has become a product, and the enzyme moves along to the next substrate. ¨. If enzymes were

What is the word and symbol equation for aerobic respiration? * Glucose + Oxygen = Carbon Dioxide + water (+ energy) * C6 H12 O6 + 6o2 = 6CO2 + 6H20 What is the word and fermentation equation for anaerobic respiration? * Glucose = Lactic Acid * Glucose = Ethanol + Carbon Dioxide (=energy) – with this equation the ethanol and Co2 breaks downs the sugars into products e.g. like bread is made using yeast where the sugar breaks down into products. FERMENATION is where things respire

There are several differences between unsaturated and saturated fatty acids. Unsaturated fatty acid is made of carbon and hydrogen bonds that does not mix well with water. Unsaturated fatty acids are solids at room temperature. They are found in food sources such as cheese, red meats, coconut oil, whole milk dairy products. Unsaturated fatty acids are structurally designed with a single carbon of a single carbon double bond, and hydrogen bonds. They are liquids at room temperature. Unsaturated fatty

present is to put it with limewater and if it goes cloudy it means that carbon dioxide is present. “During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest.”(BBC, 2015). “Respiration is the release of energy from glucose or other organic substances. Energy is required for growth, repair, movement and other metabolic
