of two ATPs are produced as the process uses two ATPs and produces four. Glycolysis consists of ten chemical reactions; each reaction is catalysed using a different enzyme. Oxygen is not required during glycolysis so it is considered anaerobic respiration. Glycolysis must be regulated so that energy is produce only when required. During glycolysis there are three enzymes that catalyse or inhibit the rate of reaction. These are hexokinase‚ phosphofructokinase and pyruvate kinase. During the first

Action of enzymes as catalysts in biochemical processes * Enzymes acts as catalyst and increase the rate of all the chemical reactions. * Enzymes are also described by two properties like all other catalysts. It composed of two main functions. * The first function is that‚ they increase the rate of chemical reactions by without consumed themselves or undergo any change or alteration in the reaction. . ( Zemitec et‚al 2008). * The second function is‚ they increase reaction rates

If oxygen is available‚ the process is known as ____aerobic__________ respiration. Name two sources of oxygen: 1. The aerobic pathway consists of glycolysis + ________________ + ___________________. The net result of one glucose molecule is ___ ATP. 9. The process of restoring the
Premium Adenosine triphosphate Muscle Cellular respiration
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

protons through the inner mitochondrial membrane. The main theory behind chemiosmosis is call Chemiosmosis theory‚ and was developed by Peter Mitchel in 1961. 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

rate than if you are doing the contractions as fast as you can. 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. Stopwatch. – To record the time it takes for

If temp gets too high enzyme activity will diminish and the proteins. Cycles of freezing and thawing can denature proteins. Oxygen concentration: The paradoxical nature can be both toxic and essential to life. 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

The Great Metabolic Race Metabolism comprises of a vital set of biochemical reactions that all living organisms require to sustain life. For a marathon runner‚ their physiological response to strenuous exercise depletes both their fats and carbohydrate storage in order to supply energy in the form of Adenosine Triphosphate (ATP). ATP is the energy form that the human body uses for biological processes such as movement and synthesis of biomacromolecules. In regards to running a marathon‚ the athlete

Analysis: In this lab we measured the rate of respiration of germinating mung beans and germinating peas at room temperature and 10 degrees Celsius. The rates of respiration at room temperature were higher than the rates of respiration in cold water. The reaction rate of the germinating peas at room temperature was .0125 ml/min and the reaction rate of the peas at 10 degrees Celsius was .0095 ml/min. The same is true for the germinating mung beans. At room temperature the rate of reaction was .0105
