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 ___________

Which of the following characteristics is unique to angiosperms compared to other plant groups?

(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.

Which of the following sequences correctly represents the flow of electrons during the light reactions of photosynthesis?

Technology issues are a legitimate reason for late submissions.

During cellular respiration, after pyruvate is oxidized into acetyl-CoA, but prior to the citric acid cycle, where is most of the potential energy that was stored in glucose?

What are the two distinct life cycles that viruses can undergo when they infect a host organism?

Progesterone is known as the “pregnancy hormone” because it initiates numerous signaling pathways during fetal development. Progesterone, being a hydrophobic steroid hormone, can easily diffuse in and out of any cell, so why does it only affect certain cells?

The process begins in the cytosol.
