In which cellular sublocation do the reactions of glycolysis occur? A. the mitochondrial matrix B. the mitochondrial intermembrane space C. the cytosol D. the endoplasmic reticulum

The proton-motive force is a measure of the potential energy generated across the mitochondrial inner membrane during electron transport. Explain the factors that constitute this potential energy, that will be converted to the chemical energy of ATP by the cell. (4)

Which transporter is typical of inner membrane of mitochondrial membrane? A. Pyruvate transporter B. H+ -ATPase C. Amino acid transporter D. Sugar transporter E. Lipid transporters

Select the correct pairing of a structure and the process it is associated with.    A. Schwann cells……..muscle contraction  B. ATP synthase…..electron transport chain  C. H+ pump……facilitated diffusion  D. Mitochondria…..protein synthesis

The cholesterol synthesized by cells uses which component of the glycolytic pathway as a starting point?a. glucoseb. acetyl CoAc. pyruvated. carbon dioxide

Saccharomyces cerevisiae, known as brewer’s or baker’s yeast, is commonly utilized in the fermentation process of wines as it can tolerate high alcohol concentration and very low pH. How many molecules of ATP and carbon dioxide will be produced in one hour if one cell can uptake 200 sucrose molecules in 20 minutes? a. 400 ATP and 400 CO2 b. 800 ATP and 800 CO2 c. 1200 ATP and 1200 CO2 d. 2400 ATP and 2400 CO2

Cyanide is a poison that works by inhibiting cytochrome c oxidase, which is a protein that uses oxygen to increase the concentration of hydrogen ions across the mitochondrial membrane. Using what you know from this unit, explain why consuming cyanide is lethal.
