Imagine that you develop a procedure to measure the pH of in the matrix and the intermembrane space of a mitochondrion. What pattern of pH would you see? O The pH in the intermembrane space will contain more H+ and have a lower pH compared to the matrix. The pH in the intermembrane space will contain more H+ and have a higher pH compared to the matrix. The pH within the matrix will contain more H+ and have a lower pH compared to the intermembrane space. The pH within the matrix will contain more H+ and have a higher pH compared to the intermembrane space.

The mitochondrion pumps H+ from the matrix into the intermembrane space. Which region is more acidic, the matrix or the intermembrane space? Why?
Which of the takes place during oxidative phosphorylation in mitochondria? a. protons are pumped from the matrix to the intermembrane space b. protons are pumped from the intermembrane space to the matrix c. electrons are pumped from the matrix to the intermembrane space d. electrons are pumped from the intermembrane space to the matrix e. NADH is pumped from the matrix to the intermembrane space
What would be the effect on ATP production during chemiosmosis and oxidative phorphorylation, if the pH within the inner membrane space of the mitochondrion were decreased, assuming no effect of pH on the structure of proteins in the membrane? a) it would increase b) it would decrease c)it would stay the same
It has been estimated that mitochondria occupy 20% of the volume in the human body. For a 70- kg adult, the average number of mitochondria has been estimated to be 1 × 10 (10,000 trillion). Using this information, provide a rough estimate of the average mass of a mitochondrion.
a) At the organelle/molecular level inside a mitochondrion, wWhy do cells engaged in aerobic cellular respiration need O2? At what points during aerobic cellular resp is CO2 released? b) O2 and CO2 do not dissolve in water easily but cells must be moist to have functional phospholipid bilayers. For air breathers, moist lungs might collapse and stick together so what prevents this? c) Aquatic animals contend with the relatively lower O2 levels in water, but at least they don’t have to deal with ventilating lung. Complex gills like in fish maximize O2 exchange with a counter-current system ensuring there is always a gradient between the water and the blood. How does this ensure there is always a gradient between the water and the blood? (many people mix this up so think carefully)
