depolarization in neuronal action potentials. Sodium channels open‚ increase of sodium INTO cell. Phase 1- sodium channels close‚ potassium channels close‚ decrease in potassium and sodium. Calcium channels open‚ increase of calcium into cell. Phase 2- Plateau phase‚ membrane still depolarized (contract). Potassium channels closed‚ L-type calcium channels stay open. Lasts 0.2 seconds/200 milliseconds. Phase 3- second set of potassium channels open‚ potassium decrease. Failing membrane potential

Question 1: Make a prediction about the basal metabolic rate (BMR) of the remaining rats compared with the BMR of the normal rat you just measured. Your answer : c. The BMR of both remaining rats will be lower than the normal rat’s BMR. Predict Question 2: What do you think will happen after you inject thyroxine into the three rats? Your answer : a. The normal rat will become hyperthyroidic and develop a goiter. Predict Question 3: What do you think will happen after you inject TSH into the three rats

Introduction: Every muscle has lactic acid.According to many people Lactic acid is nasty stuff produced in our muscles during exercise‚ cause soreness‚ muscle fatigue‚ does not contribute to exercise performance‚ muscle does not use it for fuel‚ and better athletes makes less of it. But they all are wrong or in other words they are a lay. Instead Lactate acid is made of Lactate ion called (Lactate) and Hydrogen Ion. C3H6O3----->C3H5O3++H- C2H3OHCOOH--------->C2H3OHCOO+ +H- Hydrogen ion is the acid
