Summary Introduction

To determine:

The mechanism of the sodium-potassium pumps, which helps in moving ions across the cell membrane.

Introduction:

The plasma membrane is a semi-permeable membrane which allows certain molecules to move in and out across the membrane. There is a different mechanism like osmosis, diffusion, and active transport. The sodium-potassium pump moves ions across the cell membrane by the process of active transport.

Expert Solution & Answer

Explanation of Solution

Active transport uses energy to move molecules against a concentration gradient. The cytosol of animal cells contains a concentration of potassium ions (K+) much higher than that in the extracellular fluid. These concentration gradients are established by the active transport of both ions. It uses the energy from the hydrolysis of ATP to actively transport three molecules of Na+ ions out of the cell for every two molecules of K+ ions pumped into the cell.

Conclusion

Active transport is the movement of molecules across a membrane from a region of their lower concentration to a region of their higher concentration, in the direction against the concentration gradient.

Imagine you are a botanist.  Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI).   Field Notes:  Specimen collected from shaded area along stream in South Cumberland State Park                 (Grundy County, TN). Laboratory Analysis:  Body:  Large leaves emerging from underground rhizome. Size: 63 cm  Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves:  Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History:  Diploid sporophyte dominant generation.  Haploid spores germinate into heart-shaped, haploid, gametophyte.  Water required for fertilization; no seed is produced.  Diploid zygote develops into sporophyte.
