The human body is a very complex working system and it requires a lot of energy to function properly. The human body eats food molecules that contain nutrients in order to get the energy needed to function. Once these food molecules are broken down in the human body some of the nutrients are made into glucose‚ which is an energy source. This glucose is not quite usable as one whole thing so our body breaks down even more into other molecules like pyruvate. Eventually the human body needs to make

Cycles in Biology Cycles in biology play a fundamental role in the world that we live in. Cycles occur all around and inside of us in many different forms‚ from the Krebs to the Calvin cycle. There are large scale cycles happening and they are essential in regulating the nutrients and substances that are around us which without‚ life on earth could no function. One of the largest cycles that occurs all around us is in everyday life is the carbon cycle. The current atmospheric

Here is a brief outline of the theory (now pretty much accepted as fact): Throughout respiration carrier molecules (NAD and FAD) are produced‚ which carry electrons. These pass electrons through to a chain of proteins which also act as electron carriers (This whole chain‚ from NAD and FAD to the proteins is called and electron transport chain

The science backing up my hypothesis: The higher the intensity of any type of exercise the more lactic acid is produced in a certain amount of time‚ this is by a means of anaerobic respiration. Glucose+ Oxygen = Carbon Dioxide+ Water. Equipment: plastic or wooden pegs. – Because the exercise isn’t too strenuous on the body and it is a reliable way to showcase the toll of muscle fatigue.

Obligate Aerobes rely on aerobic respiration for ATP and they use oxygen as the terminal electron transport chain. Microaerophilic require O2 from growth but they are damaged by normal atmospheric levels of oxygen and don’t have efficient ways to neutralize the toxic forms of oxygen such as
