<u>Answer</u>:
<em>Sodium potassium pump works by following several steps.
</em>
<u>Explanation</u>:
<em>1. Carrier protein binds three molecules of Na+
</em>
<em>2. ATP is split, phosphate bonds to carrier.
</em>
<em>3. Carrier protein changes shape, and deposits Na on the outside of the cell.
</em>
<em>4. Carrier binds two molecules of K
</em>
<em>5. Phosphate is released.
</em>
<em>6. Potassium is released inside the cell
</em>
Sodium -potassium pump is essential to maintain the concentration of sodium and potassium outside and inside the cell respectively.
It is the function of sodium potassium pump to transport sodium out of the cell and potassium inside of the cell against a concentration gradient.
<em>Thus it is an active transport mechanism.
</em>
Answer:
Wernicke's area
Explanation:
The Wernicke's area is a part of the brain located in the temporal lobe of the left side of the brain. It is responsible for language development, comprehension of speech and expression.
When this part of the brain is damaged or lesioned, its functions will be impaired. The disorder is called Wernicke's aphasia and the patient will speak in fluent phrases that lack meaning.
Answer:
Speeding up chemical reactions by lowering the activation energy.
Explanation:
B. A form of energy coupling refers to using the release of energy from exergonic hydrolysis of ATP to initiate other endergonic reactions for cellular metabolism.
Examples of abiotic factors are water, air, soil, sunlight, and minerals.Biotic factors are living or once-living organisms in the ecosystem.
Biotic describes a living component of an ecosystem; for example organisms, such as plants and animals.
Examples Water, light, wind, soil, humidity, minerals, gases.
