Sodium ions enter the cell through the open sodium channels. The positive charge that they carry makes the inside of the cell slightly less negative (depolarizes the cell). When the depolarization reaches a certain threshold value, many more sodium channels in that area open. More sodium flows...
When receptors open at the neuromuscular junction does sodium travel in or out of the muscle fiber? This binding causes the nicotinic receptor channels to open and let sodium ions enter the muscle fibre. If enough of these sodium ions enter the muscle fibre to raise it from its resting potent...
Since magnesium deficiency can also increase the risk for heart palpitations or arrhythmias, magnesium ascorbate can be considered in those at risk. Sodium Ascorbate – This formulation contains both sodium (~100 mg) and 900 mg of ascorbate. Those who are on a low-salt diet should avoid this...
While the SGlut-1 transport protein is operating, both sodium and glucose enter the cell. What is providing the energy to move the glucose against its concentration gradient? Explain how the energy of a concentration gradient can be used to synthesize ATP by oxidative phosphorylation. What p...
a combination of six chemicals that have been approved for pesticide use since the 1950s and are effective for controlling spiders.Pyrethrins work by keeping certain nerve cell channels permanently open, allowing sodium ions to flood in, which negatively impacts their nervous system. Thankfully, thei...
How does water move across the cell membrane?Water Movement:Water is the one compound that humans have designated as necessary for life to exist on this or any planet. So far, we might be correct. Water makes up to 60% of an adult humans body mass. In some organisms it is as high ...
How does acetylcholine enter the synaptic cleft? a. active transport b. simple diffusion c. facilitate diffusion d. exocytosis e. endocytosis Acetylcholine: Acetylcholine is the main neurotransmitter released within the parasympathetic nervous s...
Furthermore, the infectivity of antibody-opsonized immature DENV was found to be dependent on cellular furin activity, suggesting that immature virions mature upon virus entry17. An early study suggested that antibody-opsonized virions enter the cell via phagocytosis22. This was based on the ...
Transcriptional bursting has been linked to the stochastic positioning of nucleosomes. However, how bursting is regulated by the remodeling of promoter nucleosomes is unknown. Here, we use single-molecule live-cell imaging of GAL10 transcription in Saccharomyces cerevisiae to measure how bursting change...
There are different pathways through which calcium can enter the cell to initiate a cascade of intracellular events. One of the main Ca2+ influx routes in cells is represented by store-operated Ca2+ entry (SOCE). SOCE is mediated by a functional interaction between STIM1 Ca2+ sensor of endopl...
