The mitochondrion gets its name as “the powerhouse of the cell” because the majority of the ATP produced in our cells occurs within by the motor protein ATP synthase. The energy to do this comes via ___________

(4.5 pts) Cyanide is a potent poison to obligate aerobes like humans. It acts by preventing the function of O2 during cellular respiration. Most facultative anaerobes, such as E. coli, are not harmed by cyanide because they can survive without access to abundant O2. A) What is the function of O2 during aerobic cellular respiration? B) When O2 is not present or cannot be used, what cellular process is directly responsible for the production of ATP, allowing E. coli to continue to survive? C) Fermentation allows this process continue to take place. What molecule does fermentation regenerate? Describe the reaction used in this process.

MAPKs (mitogen-activated protein kinases) are a class of enzymes involved in many signaling pathways, including cell division, gene expression, stress response, and programmed cell death. What would you expect is the primary function of a MAPK enzyme?
