In what ways are autorhythmic fibers similar to and different from contractile fibers?

Biology

Leto [7]3 years ago
5 0
I think Autorhythmic fibers are fibers that are self excitable or on their own for example some cardiac muscle. They  repeatedly generate action potentials that trigger heart contractions.They continue to stimulate a heart to beat even when it is removed from the body. In comparison to contractile fibers, autorhythmic fibers are self excitable and do not require nervous system stimulation to trigger contractions. Contractile fibers have stable resting membrane potentials of -90mV, when a contractile fibers reaches threshold by action potential, the voltage gated fast sodium ions channels will open.

Air pollution:
Aleksandr-060686 [28]

Answer:

Since the early 1900s, many glaciers around the world have been rapidly melting. Human activities are at the root of this phenomenon. Specifically, since the industrial revolution, carbon dioxide and other greenhouse gas emissions have raised temperatures, even higher in the poles, and as a result, glaciers are rapidly melting, calving off into the sea and retreating on land.

A convection cell is best described as
labwork [276]
Convection cell in the sun's rays are the ones that carry energy to travel within its surface and outside.

There are three types of heat transfer or heat propagation; conduction, convection and radiation. Heat transfer is the process by which heat projects externally however, depending on the temperature and pressure. Also called the movement of heat from a low temperatured state which increases as heat progresses.
Conduction is the heat transfer by contact, immediate contact.
Convection is the transfer of heat through air and water.
<span>Radiation is the transfer of heat regardless of the presence of atoms or particles. </span>

What role does H20 have in cellular respiration
Marizza181 [45]

Answer:

H_{2}O or Water is a very important component of the cellular respiration. However, it does not act in the process of cellular respiration directly, but is produced at the end of the cellular respiration during Oxidative Phosphorylation or Electron Transport System.

Basically, what happens is during the stages ETS, the NADH and FADH_{2} gets converted into NAD and FAD whereas the H^{+} ion accumulates into the inter-membrane space, which then passes through the ATP synthase molecule from the inter-membrane space to the matrix thus, stimulating the ATP synthase molecule to produce ATP the most important product of cellular respiration. This H^{+} ion when enters the matrix gets utilized to form H_{2}O by getting bound to O_{2}. But if no H_{2}O is produced in the final stage and the H^{+} ion gets accumulated in the matrix then the cellular machinery will malfunction and the production of ATP will stop. Thus, by this fact, we know that H_{2}O has a very important role in cellular respiration.
