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
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.

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…
A series of chemical reactions in cytoplasm of a cell
Glucose split in half (Small amount of energy is released and captured in ATP)
Glucose = completely broken down and used to produce more ATP (Cellular Respiration)
Two distinct phases
Uphill = preparatory phase (input 2 ATP = endergonic)
Downhill = payoff
Glucose has a lot of potential energy
Energy in glucose is not readily released unless energy from ATP is first added
When ATP is added, resulting sugar molecule has…
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…

Stages of Photosynthesis
1: Pigments capture energy from sun
2: Light energy is converted to chemical energy (ATP and NADPH)
-Energy stored in chemical bonds
3: ATP, NADPH and CO2 used to make glucose

Photosynthesis captures energy from the sun
and stores it as glucose.
The formula for photosynthesis is 6H2O + 6CO2
----------> C6H12O6+ 6O2
Energy in sunlight is in the biosphere introduced

Research Essay - Diabetes a deficiency disease
All living organisms need food to survive. Food provides energy for all the body functions and the manufacture of cells. The food we eat is digested into nutrients using physical and chemical processes. The body can then absorb the nutrients into the blood stream. (BBC 2011) Sugar and fats are broken down into energy using enzymes such as amylase in the stomach. Protein in food breaks down into amino acids which are used to build muscles and form the…
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
