Because it is not secreted and reabsorbed.
Inulin clearance is done by which the filtering capacity of the glomeruli is determined by measuring the rate at which inulin is cleared from the plasma. It is considered as the most accurate substance to use because it is inert polyssacharide that passes readily in the glomeruli without being reabsorbed in the tubules. Inulin is seldom used in clinical testing but used in research. Creatinine clearance is the more commonly used test to assess function of kidney clinically.
Answer:
cross bridge formation, power stroke, cross bridge dissociation, cocking of myosin
Explanation:
The signal for the beginning of muscle contraction is acetylcholine (Ach) released from the presynaptic cell which then binds to its receptor on the muscle cell. This event causes depolarization and consequently the release of Ca ions from the sarcoplasmic reticulum. Ca helps the formation of actin-myosin cross bridge. The movement of myosin heads causes the move of actin and this process is called power stroke. In the absence of ATP, the myosin head will not detach from actin(ATP binding causes the myosin head to detach from the actin and causes cross bridge dissociation). Energy released form the ATP hydrolysis changes the myosin head into a cocked position.
Glycolysis is the first step in the respiration pathway. The amount of oxygen available after glycolysis determines whether the rest of the reaction is aerobic (Krebs Cycle and Electron Transport Chain) or anaerobic (Fermentation).
