Lecture 24 Anaerobic Cellular Respiration

Question 1

What is one of the most common (non oxygen) electron acceptors?

Answer 1

NO3-

Question 2

Nitrite Respiration

Answer 2

when nitrate serves as a terminal electron acceptor, using the complex nitrate reductase

Question 3

Denitrification

Answer 3

nitriate (NO3-) –> Dinitrogen (N2)

Answer 4

yes!

Question 5

True or False: metabolic capabilities are largely associated with phylogenic group

Answer 5

false! metabolic capabilities are found scattered among various groups of bacteria

Question 6

All anaerobic processes are ____ efficient than aerobic cellular respiration.

Answer 6

less

Question 7

What are the shared characteristics of cellular respiration?

Answer 7

a membrane system, the generation of an ion gradient, and the formation of ATP via ATP synthase
