Principles of Biology : Quiz 8 Study Guide


We will take Quiz 8 on Wednesday, October 15. I recommend that you answer these questions yourself or with classmates. This not a graded assignment, nothing is to be turned in. These questions are just to help you prepare for this quiz.
Reading: You should read Chapter 7, How Cells Harness Energy, in the text book. This quiz covers up to page 128 (The Oxidation of Pyruvate to Acetyl-CoA).

There are flashcards and animations on the Aris site you should study.   Quick Link to the Aris Site.

Questions to consider
1) What is the overall chemical equation of the complete oxidation of carbohydrates like glucose?
2) What is oxidation? What is reduction?  What are redox reactions?
3) What is NAD+? What is NADH? What role does this molecule play in metabolism?
4) What is ATP and how does it drive endergonic reactions?
5) What is the ultimate "goal" of cellular respiration?
6) What is "substrate-level" phosphorylation and how does it differ from "oxidative phosphorylation?
7) What is glycolysis?
8) Where does glycolysis occur?
9) What is the starting molecule and what is the ending molecule?
10) Examine Figure 7.6 on page 125. From the vertical categories on the left of the figure, what are the three stages of glycolysis?
11) What is the equation for the overall reacitons of glycolysis?
12) Who has this biochemical pathway?
13) What happens when NADH accumulates in a cell?
14) What are the two processes that can accept electrons from NADH and recycle NAD+?
15) What is aerobic cellular respiration?
16) What is anaerobic respiration?
17) What do animals do when forced to do anaerobic respiration?
18) What do yeast cells do when forced to do anaerobic respiration?
19) What is "fermentation?"
20) What is the ATP and NADH yield of glycolysis?
