The fixed pattern of changes in membrane potential during an action potential is coordinated by the sequential opening and closi

baherus [9]

<h2>Na-K channels</h2>

Explanation:

Brief sequential change in the membrane potential of excitable cells after stimulus is called action potential whereas membrane potential represent charge difference across the membrane
In a typical neuron cell, membrane potential of cytoplasm is negative at rest and hence called resting membrane potential
Resting membrane potential of excitable cells is established by Na+ K+ pump and maintained by K+ leaky channels at rest
Phases of action potential includes: depolarization, repolarization, hyperpolarization and resting membrane potential
Depolarization starts when a threshold stimulus is applied on a neuron when via Na+ mechanically operated channels that trigger action potential
Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
Repolarization starts with the efflux of K+ by the opening of voltage gated K+ channels, voltage gated K+ channels starts to open when voltage gated Na+ channels becomes inactive
Hyperpolarization occurs due to excessive efflux of K+ by voltage gated K+ channels
Additional efflux of K+ occurs due to slow inactivation of voltage gated K+ channel

Cell respiration begins with

irinina [24]

Answer:

Cell respiration begins with Glycolysis .

Explanation:

Glycolysis is the first and initial step in the cellular respiration. Cellular respiration is the anaerobic process, which takes place in cytosol of the cells. Two molecule of pyruvate(CH3COCOO-) are formed from 1 molecule of glucose(C6H12O6)through glycolysis. The NADH and ATP are high energy molecules formed when the free energy are released. It is the process which takes place through a series of ten enzyme catalysed reactions. 10 enzymes are required to break down the sugar molecule. It occurs in cytoplasm.

shepuryov [24]

<u>Answer:</u>

The most appropriate answer option is B. must be certified if requirements are met.

<u>Explanation:</u>

The forensic biologist must be certified if requirements are met by the American Board of Criminalistics.

Option B seems to be the most appropriate answer to complete the given statement.

Forensic Science requires specific expertise for every field. Therefore, forensic biologists have certain requirements that they need to meet in order to achieve professional certification.

The skin mainly protects the body against infection by what

Ivanshal [37]

It is like a barrier, or wall. It helps infection and bacteria stay out. It can also help you indicate whether you are getting infection in the inside of your body. if you're skin is inflamed, that is a sign of disease or infection.

I hope this helped you!

Brainliest answer is always appreciated!<span />
