To ease into cellular respiration student played a trivia game to introduce them to some of the key players in cellular respiration.

1. Intro to cellular respiration
 Trivia Time
 Get in groups of 2-3 (work with people
you usually do not work with)
 Take notes while we do this

2. Which part of a eukaryotic cell is
involved in cellular respiration?
 nucleus
 endoplasmic reticulum
 mitochondria

3. Which is not a by-product of
cellular respiration?
 ATP
 Water
 Glucose

4. In the presence of oxygen, the first
stage of cellular respiration is ...
 Glycolysis
 The citric acid cycle
 Electron transport

5. Define cellular respiration
 Cell respiration is the controlled release
of energy from organic compounds in
cells to form ATP.

6. Overview of Cellular Respiration

7. In glycolysis, each glucose molecule is
broken down to two molecules of …
 acetyl coenzyme A
 pyruvate
 citric acid

8. Without oxygen, glycolysis allows
cells to make small amounts of ATP
through a process called ...
 oxidative phosphorylation
• Another way to make ATP
 electron transport
 fermentation
• There are two types of fermentation:
• Lactic Acid fermentation (sore muscles)
• Alcohol fermentation

9. Upon entering the mitochondria, pyruvic
acid molecules are converted to _____
molecules to be used in the citric acid
cycle
 citric acid
• A six carbon compound in the citric acid cycle
 acetyl coenzyme A
• An enzyme joined with two carbons (think of
Coenzyme A as an escort for carbon molecules into
the citric acid cycle)
 fumaric acid
• An intermediary in the citric acid cycle which is used to
produce ATP. It can also be added to candy to make
it taste sour and even be used to treat psoriasis.

10. In a eukaryotic cell, most of the ATP
derived from glucose during cellular
respiration is produced by ...
 Glycolysis
 The citric acid cycle
 The electron transport chain

11. Glucose and _______ are consumed
during cellular respiration.
 carbon dioxide
 oxygen
 water

12. Most of the ATP produced by the electron transport
chain is generated from the oxidative
phosphorylation of NADH and ____ .
 FADH2 flavin adenine dinucleotide
 FAD
 NAD+

13. FAD can be reduced to FADH2

14. FAD can be reduced to FADH2
