Lab / Muscle Fatigue What are the affects of anaerobic respiration on you muscles? Background Normally‚ muscles use oxygen through a process known as cellular/aerobic respiration to make energy (or ATP) from sugar (glucose). This process is very efficient and produces 38 ATPs for each molecule of glucose. Carbon dioxide and water are the results of this reaction. When muscles undergo rigorous exercise they require more oxygen to make ATP than the blood can supply. At this point the muscle is forced

human body? To ensure that fluid levels inside and outside the cell are balanced. How does your electrolyte work in the functioning of nerves and muscles? Like athletes when they workout they lose salt by sweating. That’s why they try to contain salt before they work and after‚ to avoid cramps and such. The cramping effects the nerves and muscles‚ because they begin to shut down. As the salt in your body fades away. What are some of the specific health problems that can arise from an imbalance

Staying active means keeping your body functioning at a high level. Regular exercise will maintain the performance of your lungs and heart to most efficiently burn off excess calories and keep your weight under control. Exercise will also improve muscle strength‚ increase joint flexibility and improve endurance. Another main benefit of physical activity is that it decreases the risk of heart disease‚ the leading cause of death in America. Additionally‚ it

Table 1 was our observation for the control group‚ or the ChR2- as we called it. Living up to its name‚ the larvae from this plate did not contract as we increased the MRR‚ and continued to move. Although the number of waves per larva was different‚ it was higher than the waves produced in Table 2‚ the ChR2+ group. Larvae from this plate contracted immediately when the light was turned on and only produced waves during the interval the light was not on. Because the light flashed a set amount of times

Attach a copy of your experimental recordings showing a period of spontaneous contractions and the response to stimulating the nerves at 20 Hz with both a voltage that produced only a modest response and the voltage that produced the maximal response. 1) Briefly describe the response of the ileum when it is unstimulated and during stimulation of the nerves. When the ileum is unstimulated‚ the contraction peaks at around 8mV and goes down to around 1 mV. This is repeated steadily. During
