The mesenteric veins and the hepatic portal vein
The long-term benefits of participating regular physical activity include: loss of weight and eventually settling to a healthy weight, body already adapts to dynamic movement, one's heart is also getting larger, and bones become denser. In this case, the short terms effects are increase in hear rate, increase in stroke volume and decrease in pH of the blood.
<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:
The correct answer is NAD+
Explanation:
Glycolysis is the process that occurs in almost all the cells. It occurs in the cytoplasm in both prokaryotes and eukaryotes. In glycolysis partial oxidation of glucose takes place step wise and one glucose molecule gets convert into 2 pyruvate.
The molecule that helps in the partial oxidation of glucose is NAD+. NAD+ is an electron carrier that harvest energy in a series of gradual step from glucose in the form of electrons and gets reduced into NADH.
Then this NADH is used to feed electrons in the ETC during oxidative phosphorylation to make ATP and get regenerated into NAD+. So the correct answer is NAD+.
Can u refrase the question so I can answer it
