Question
-Why is cellular respiration important?
It produces oxygen gas, which is essential to cell functions.
It breaks down carbon dioxide, which is toxic to cells.
It generates ATP, which cells can use to do work.
It generates chemical gradients, which have potential energy.
-How would the electron transport chain be affected if oxygen was not present in the cell?
The electron transport chain would stop until the cell found another source of hydrogen ions.
The electron transport chain would stop because the carrier proteins would have no way to unload electrons.
The electron transport chain would continue only if glycolysis continued producing NADH.
The electron transport chain would continue, but it would produce fewer ATP per glucose molecule.
-use the following words: protons, NADH, electron gradient, ADP, FADH2, ATP, ATPsynthase, water, proton gradient, electrons
A molecule generated in both glycolysis and Krebs cycle, called ____________ , donates ____________ to the first protein in the electron transport chain.
At the same time, a molecule generated only in the Krebs cycle, called ____________ , donates ____________ to the second protein in the electron transport chain.
As the ____________ move through the transport chain, ____________ move through membrane proteins from the matrix to the intermembrane compartment.
At the end of the electron transport chain, ____________ bind to oxygen, forming ____________ .
The electron transport chain creates a(n) ____________ , which dissipates through an enzyme called ____________ .
As ____________ move through this enzyme, phosphate is added to ____________ , forming ____________ .
Explanation / Answer
Answer to first question;
Cellular respiration breaks down glucose and provides ATP.
Glucose+O2->CO2 + H2O + ATP.
This ATP is used by cells for normal functioning.
Hence option 3rd is correct.
