How does the sodium-potassium pump contribute to the net negative charge of the interior of the cell?

Biology
1 answer:
Slav-nsk [51]3 years ago
6 0

Answer:

By moving three positively charged ions out of the cell for two positively charged ions entered.

Explanation:

The sodium-potassium pumps are the pumps located in the plasma membrane and are involved in the active transport of sodium-potassium ions. Binding of ATP and three sodium ions to the sodium-potassium pump is followed by hydrolysis of ATP and the use of released energy to bring about the conformational change in the shape of the pump.

This allows the bound three sodium ions to move out of the cell. As the sodium ions are released out of the cell, two potassium ions enter into the cell through the pump.

Since three positively charged sodium ions are expelled out of the cell for two positively charged potassium ions entering the cell, the net effect is making the interior of the cell negative with respect to its exterior.

What do you already know about conservation? Think about wildlife and the environment
Elenna [48]

Answer:

Wildlife is living organisms, like plants and animals that live anywhere in the world that they are not isolated in a certain area.

Explanation:

Each wildlife creature lives in an ecosystem that their bodies can tolerate and be able to survive in.

  • Penguin´s bodies are adapted to keep them warm in Antarctica, if they are in warm climates they would overheat.
  • Cold-blooded animals like iguanas cannot live in cold climates because their body temperature would be according to what they feel, so living in cold climates would cause them to die from hypothermia.

Write a paragraph about how
den301095 [7]

Answer:

Climate change is rapidly becoming known as a tangible issue that must be addressed to avoid major environmental consequences in the future. Recent change in public opinion has been caused by the physical signs of climate change–melting glaciers, rising sea levels, more severe storm and drought events, and hotter average global temperatures annually. Transportation is a major contributor of carbon dioxide (CO2) and other greenhouse gas emissions from human activity, accounting for approximately 14 percent of total anthropogenic emissions globally and about 27 percent in the U.S.

Fortunately, transportation technologies and strategies are emerging that can help to meet the climate challenge. These include automotive and fuel technologies, intelligent transportation systems (ITS), and mobility management strategies that can reduce the demand for private vehicles. While the climate change benefits of innovative engine and vehicle technologies are relatively well understood, there are fewer studies available on the energy and emission impacts of ITS and mobility management strategies. In the future, ITS and mobility management will likely play a greater role in reducing fuel consumption. Studies are often based on simulation models, scenario analysis, and limited deployment experience. Thus, more research is needed to quantify potential impacts. Of the nine ITS technologies examined, traffic signal control, electronic toll collection, bus rapid transit, and traveler information have been deployed more widely and demonstrated positive impacts (but often on a limited basis). Mobility management approaches that have established the greatest CO2 reduction potential, to date, include road pricing policies (congestion and cordon) and carsharing (short-term auto access). Other approaches have also indicated CO2 reduction potential including: low-speed modes, integrated regional smart cards, park-and-ride facilities, parking cash out, smart growth, telecommuting, and carpooling.
