NADH and FADH2 are both electron carriers that donate their electrons to the electron transport chain. The electrons ultimately
maria [59]

Answer:

Explanation:

NADH and FADH2 are both electron carriers of the electron transport chain. NADH gives up its electrons starting from Complex I, which has a higher energy level compared to other complexes. Energy is given off to pump protons across the membrane by the time electrons are transferred to ComplexIII. More electrons are pumped across the membrane as electrons move to Complex IV. Because NADH commenced giving up its electrons from Complex I (higher energy level complex), more protons are pumped across the membrane gradient, which enables ATP synthase with more power to produce 3ATP molecules per NADH molecule.

On the other hand, 2 molecules of ATP are generated by FADH2 because it starts by giving up its electrons to ComplexII. It missed a chance to pump protons across the membrane when it passed Complex I. By the time the electrons reach Complex IV, less protons have been pumped. The lesser the protons to power ATP synthase, the lesser the ATP molecules produced.

lisabon 2012 [21]

Answer:

I might be wrong but im guessing 600

Explanation:

Since there is one molecule of glucose used per 6 molecules of carbon dioxide released, if you have 100 molecules of glucose, then you multiply the carbon dioxide by 100 which is 600. Thats what I would say but I might be wrong.

MAVERICK [17]

Answer:

An efficient way to search for and insert a value in a cell when the desired value is stored elsewhere in the worksheet or even in a different workbook is by using lookup functions.

Explanation:

  • Lookup function is the built in function of excel that helps in returning the certain value form specific row or column.
  • When the value is stored in the worksheet we can easily insert that desired value in the cell by the use of lookup functions.
  • VLOOKUP  and HLOOKUP are the lookup unctions that searches the value in column and row respectively.

Explain in detail how galen, a physician during the middle ages, expanded on hippocrates’ theory of the four humors and explain
Ann [662]
<span>Hippocrates believed that there are four humors in human body which need balance for a healthy being. These were:
Blood, phlegm, yellow bile, and black bile.</span>
Galen expanded the idea of the humors and introduced four temperaments which were these:
choleric (hot / dry), melancholic (cold / dry), sanguine (warm / moist), and phlegmatic (cold / moist).
Another expansion Galen did was that he gave each humor/temperament physical and psychological qualities and said that even the food items have an association with the certain humor, those foods can effect certain humor in certain ways.
