Question
Process that occurs in the cytoplasm in the absence of oxygen;
Glucose is converted to pyruvic acid; ATP and NADH are also
produced
Date:________________
Answer
glycolysis
2.
If oxygen is not present, pyruvate and NADH enter this metabolic Lactic acid fermentation
pathway; occurs in your muscles; used by bacteria
3.
If oxygen is not present, pyruvate and NADH enter this metabolic Alcoholic fermentation
pathway; produces carbon dioxide and ethanol; used by yeast
and some plant cells
4.
If oxygen is present, pyruvate is further broken down; NADH
produced is used to make large amounts of ATP
Aerobic respiration
5.
First step in the breakdown of glucose
glycolysis
6.
The reactants in cellular respiration
Glucose and oxygen
7.
The products in cellular respiration
Carbon dioxide, water, and ATP
8.
Net amount of ATP produced in glycolysis
2
9.
Where the intermediate step between glycolysis and Krebs occur
Mitochondrial matrix
10. In the intermediate step of aerobic respiration, pyruvate is
converted to this which enters the Krebs cycle

11. Besides acetyl CoA, NADH and ____________ are produced in
the intermediate step
Carbon dioxide
12. The Krebs cycle produces two electron carriers: _____ & ______
NADH and FADH2
13. A by-product of the Krebs cycle is ________

14. For each acetyl CoA that enters the Krebs cycle, ___ATP is/are
produced
1
15. NAD+ is reduced to_____
NADH
16. Most of the ATP produced from aerobic respiration occurs
during _____
ETC/chemiosmosis
17. During ___ NADH and FADH2 release ___ atoms regenerating
