Respiration Review Questions
1. The electron transport chain pumps what kind of ions into the intermembrane
space?
a. H+ = hydrogen ions or protons
2. How many ATP are produced by the complete breakdown of one glucose
molecule?
a. 38
3. In Glycolysis, list the kinds of high-energy molecules are produced and tell
how many.
a. NADH (2) and ATP (4 = total, 2 = net)
4. Glycolysis depends on a continuous supply of what molecule?
a. Glucose
5. Which of the following can occur without oxygen: glycolysis, krebs cycle or
the electron transport chain?
a. glycolysis
6. What step produces the most ATP?
a. Electron transport chain
7. Write out the chemical formula for respiration (it must be balanced)
a.
8. What is the purpose of mitochondria?
a. The mitochondria are the POWERHOUSE of the cell. They perform
cellular respiration which creates energy through the breakdown of
glucose in the presence of oxygen.

a. This great website is a great read over… ignore the information that we did not
cover in class.
8. Where specifically does photosynthesis take place?? Be as specific as possible.
a. In the thylakoid membrane, inside a thylakoid, which is in stacks of grana, located
in the chloroplast of the plant cell.
9. Write the chemical formula for photosynthesis
a. Reverse of Respiration
10. An organic compound formed is the dark reactions of photosynthesis is = PGAL (A)
A)PGAL
B) chlorophyll
D) water
C) oxygen
11. Why can’t we humans perform photosynthesis?
a. We don’t have chloroplasts
12. What proteins absorb light energy in the light reactions?
a. PS 1 and 2
Questions that apply to BOTH:
9. What purpose do the electrons serve in the electron transport chain?
a. They provide the energy to pump H+ ions across the membranes
10. What protein is in charge of the creation of ATP?
a. ATP synthase
11. Why is the H+ gradient important?
a. It is important because once it is establish, there is a higher
concentration on one side of the membrane than on the other. Thus the
atoms want to move from a high to low concentration. So the protons
will flow freely from the high concentration to the low concentration
through ATP synthase. ATP synthase turns as protons move through it
and create ATP from ADP and Pi (inorganic phosphate)
