Answer:
Selective transport enables the substances to move rapidly through the cell membrane (for instance, H2O, O2 and CO2), while other substances pass through the cell membrane more slowly. Moreover, there are also compounds that can't pass through this barrier.
Explanation:
The selective transport of the substances across the cell membrane enables the cell to maintain the homeostasis of the system by maintaining the ionic equilibrium on both sides of the cell membrane. Moreover, selective transport also is required for carrying out cellular mechanisms, since this mechanism enables the entry and the exit of macromolecules used by the cell to maintain its function and structure.
The most common mechanisms of selective transport are diffusion and transport active. Endocytosis and exocytosis are active transport process where proteins, lipids, and different types of macromolecules are transported to both sides of the cell membrane through vesicles. Polar molecules (such as for instance, calcium and iron ions) may be transported via transport active, while hormones and vitamins may be transported via passive diffusion.
Answer:
The appropriate order for the basic steps of protein synthesis are listed below
Explanation:
First step D The large ribosomal subunit joins the initiation complex preparing it for elongation stage.
Second step C Binding of mRNA by small Sub unit followed by association of a particular initiator aminoacyl tRNA that recognizes the first codon.
Third step B The P site is occupied by peptidyl tRNA carrying the growing polypeptide chain.
Fourth step A The elongation reaction transfers the peptide chain from the peptidyl tRNA in the p site to the aminoacyl tRNA in the A site.
Fifth step E The new longer Peptidyl tRNA moves from A site into the p site as the ribosome moves one codon further along the mRNA.
The clinical finding that the nurse should expect when assessing
the apical and radial pulse of a postpartum client in three hours after the
birth of the second child is the capillary refill In which it should be faster
than three seconds because with this finding, it could indicate that there is a
good perfusion of the tissues in the peripherals.
