Carbohydrates A carbohydrate is one of three macronutrients and is the most important energy source for the entire body. Men’s Health Magazine talks about how Today people are mislead by diets such as the atkins diet and sugar busters diet. These diets deceive us into thinking that our bodies actually don’t need carbohydrate and that our bodies would rather rely on fats and proteins for energy. According to the text book Nutrition An Applied Approach, this information is false, that in reality our bodies actually prefer to use carbohydrates and fats for energy, and that 60% of our daily intake needs to be Carbohydrates. When doing high intensity short duration workouts such as weight lifting our bodies rely on carbohydrates for energy. This energy produced from carbohydrates is called adrenosine triphosphate also known as ATP. What happens is the carbohydrates are broken down into glucose and undergo a process called glycosis to create this ATP. The end result of all of this is pyruvic acid. When your doing these high intensity exercises the oxygen in your cells become limited and then the pyretic acid converts to lactic acid to supply fuel for our muscles and our hearts. If a person is not consuming enough carbohydrates their body and brain then has to use alternative options for energy which can lead to ill health. Lets start with the brain, in my textbook, it says the brain on average uses 130 carbohydrates daily to function at normal capacity, so if there are not sufficient carbohydrates our body will then start to make its own energy called ketones through a process called ketosis. Ketosis is normal however if the brain has to continue using ketones for energy serious side effects can occur such as suppressed appetite, dehydration, and high blood ketone levels. Ketones are highly acidic and can interfere with everyday body

Chemistry: Protein and Monosaccharides- Glucose- Energy Essay

homeostasis of the blood pH and balance of the electrolytes. 3. Describe metabolism. Metabolism is all the chemical reactions of the body. Catabolism occurs during decomposition reactions and releases energy. (Exergonic)Covalent bonds are broke, smaller molecules are produced and energy that is used during Anabolism is released. Anabolism occurs during synthesis reactions(Endergonic) and produces protein or fat. 4. Explain the importance or water in living organisms. Water is the universal…

Understand the functioning of the body systems associated with energy and metabolism The physiology of the Respiratory System Oxygen is needed by the cells as it contributes to the stimulation of ATP which is required and essential for energy metabolism. When oxygen is impassive from the air which we breathed in and exchanged gases begin to take place among the blood and the air which is situated in the alveoli. When gas and air begin to exchange together this arises in the alveoli. Within the surface…

Cellular Energy Lab Report

Cellular Energy All organisms need energy, but only some living things can directly use the energy of sunlight. Autotrophs (producers) make their own food by obtaining energy from sunlight (or inorganic compounds). Heterotrophs (consumers) cannot make their own food, and must get their energy from food sources. Photosynthesis- carried out in the chloroplasts of plants; uses carbon dioxide to store energy in the form of glucose (organic molecules); produces oxygen 6CO2 + 6 H2O C6H12O6…

Hypoglycemia Research Paper

Importance of glucose: In order for the body to carry out its functions it needs a source of energy. This source of energy is provided by glucose. The body uses glucose to carry out many important functions such as cellular respiration to provide energy needed for metabolism. The primary source of glucose comes from our diet in the form of carbohydrates. Our body is able to digest carbohydrates into glucose molecules. Glucose can then…

steps that are consisted in cellular respiration. The main function of cellular respiration is to generate ATP for the cellular to work. Cellular respiration transfers hydrogen atoms from glucose to oxygen which forms water. The transfer of hydrogen is the key as to why oxygen is so important to harvest energy from during cellular respiration. Redox is when chemical reactions are transferred through electrons from one substance to another. When electrons are lost during redox it is called oxidation…
