<h2>Sodium channels </h2>
Explanation:
Depolarization is a result of sodium channels opening as a result of chemical or pressure-based stimuli
- Depolarization starts when a threshold stimulus applied on a neuron via Na+ mechanically operated channels that trigger action potential
- Action potential is an efficient signaling process by which distantly located cells communicate to each other
- Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
- Fast opening of voltage gated Na+ channel shifts membrane potential from -70mV to + 50mV at which voltage gated Na+ channels become inactive thus influx of Na+ abruptly stops
Because the common cold is cause by a ‘virus’.......
The answer is VIRUS
Enzymes<span> are protein molecules that are manufactured by all plant and animal cells. All cells require </span>enzymes<span> to survive and </span>function<span>. </span>Enzymes<span> are catalysts, which means that they make chemical reactions go faster, but are not changed by the reaction.</span>
