There are 5 systems that re-synthesise ATP: two of them being anaerobic and three of them being aerobic. The first energy system is the ATP/PC system, and it produces energy through a reaction where ATP-ase breaks down the triphosphate bond which releases energy when the bond is broken. For example, the energy system would be the main energy source for a 100 m sprint, or a short set of a weightlifting exercise. It can provide energy immediately, it does not require any oxygen and it does not produce any lactic acid. It does however have its negatives in that the ATP lasts only 10 seconds so can’t be used for long distance running for example.
It is the immediate energy system. Creatine phosphate is a high energy compound. Exercise intensity high PCr phosphate stored in muscle is broken down to provide energy to make ATP. When the high energy bond in PCr is broken, the energy it releases is used to resynthesise ATP. Lactic acid energy system Glucose 2ATP + 2 lactic acid + heat Glycogen 3 ATP + 2 lactic acid = heat This is the short-term energy system.
This is another effective method of resynthesizing ATP so that more energy can be released throughout the body to help carry out physical activities. This energy system is important because it comes into place immediately after creatine phosphate stores become depleted. Whilst the body recovers to re-establish CP the lactic acid system starts with the process anaerobic glycolysis. Due to lactic acid production, this energy system can only be predominant for up to 2 minutes. Therefore this substance needs to be removed from the body before it interferes with muscle contraction.
When we do intense workouts our ratio increases about 1.0, thus making our bodies work anaerobically (this means without O2). When your R.Q. is high that means our bodies are burning more carbohydrates and less fat. In turn, if you are trying to lose weight and it’s not coming off it could be because your R.Q. is too high.
4. Graph 5. Table Chainobead Construction Time Part A | 15 Seconds | 6 | 30 Seconds | 12 | 60 Seconds | 20 | 120 Seconds | 29 | Part 1B: 1. The results of the 120 seconds with the non-pop beads added to the mix didn’t hinder the enzyme’s construction rate at all except for the first trial. In the first trial 28 chainobeads were constructed, in the second trial 30 chainobeads were constructed, and in the final trial 35 chainobeads were constructed.
Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? Glucose was able to diffuse through the 200 MWCO because its molecular weight is 180. Albumin was not able to diffuse because its molecular weight is much larger than 200. 4.
AS substrates are initially added, the activity is higher and then it reaches a plateau with increase. NO. Sucrase activity reached a plateau. Correct Predictions: Optimal temperature: 40 °C (104 °F), Sucrase activity increases with increasing sucrose concentration until a plateau is reached. Incorrect predictions: Sucrase will have highest activity at ph 6 not ph 7 Warm up exercise increases body temperature making it ideal for enzyme activity Increasing myosin activity makes muscles tougher and stiff and limits free movement for performance.
Marathon runners undertake intense training and require significant amounts of carbohydrates for energy. Carbohydrates are our first source of fuel broken down to form ATP for exercise. It is this energy that is used for muscle contraction, hence carbohydrates are an excellent fuel for exercise consisting of a long duration and high intensity. The body stores carbohydrates as glycogen in the muscles and liver, however its storage capacity is limited. By an athlete’s diet being high in carbohydrates, fatigue during the event is delayed.
Any time there is a physical burning of calories that is more than the calorie intake there will be a decrease of body fat. Once a person reaches their ideal weight, defining muscle tone is another great effect of exercise. Exercise makes muscles more proficient and more operational. High intensity exercise with only a few reps will produce strength, size, and power improvements, while low intensity exercise with many reps will produce endurance. The body’s metabolic rate is increased as its need for energy is increased, and the body becomes more resourceful.
The chief argument in why the consumption of milk is so beneficial to our diet is the importance of the calcium we get from it. Drinking milk is said to be the most practical way to receive the calcium that our bodies need in order to grow and properly develop. Calcium during key years in bone development can literally make or break a persons bone health. With high amounts of calcium intake leading to stronger bones, there is less of a chance of developing osteoporosis and other potential health problems in the future. Milk is also said to help speed up weigh loss and reduce body fat, because of the indispensible mix of nutrients that appear to speed up metabolism and increase the body's ability to burn fat.
