Answer:
pH - Each enzyme has an optimal pH at which it works best, if the pH is too acidic or basic, the enzyme will start to denature.
Temperature - Each enzyme has an optimal temperature at which it works best as well. If it is too hot, the enzyme will start to denature and if it is too cold, there will be fewer collisions between enzymes and substrates.
Explanation:
Activation of muscle contraction could be a speedy event that's initiated by electrical activity within the surface membrane and transversal (T) tubules. This can be followed by unharness of metal<span> from the inner membrane system, the sarcoplasmic reticulum.
</span>Nervous stimulation causes a depolarization<span> of the muscle membrane (sarcolemma) </span>that<span> triggers </span>the discharge<span> of </span>calcium<span> ions from the sarcoplasmic reticulum.</span>
