2. produces pyruvate, nadh₂, and ______ atp molecules.
3. there are two types of ______ that take place in the cytoplasm of the cell.
4. ______ fermentation occurs in yeast, bacteria, and other microorganisms.
5. produces ______ and carbon dioxide. used for making bread and alcoholic beverages.
6. ______ fermentation occurs in the muscle cells of animals and some bacteria.
7. produces ______ that builds up in muscle cells, causing soreness during exercise.
8. both process can produce ______ atp molecules.
9. after glycolysis, the ____ cycle produces __ gas, electron carriers, and 2 molecules of ____

Explanation:

The problem involves concepts related to cellular respiration (glycolysis, Krebs cycle, electron transport chain, fermentation) and cell organelles (mitochondria, cytoplasm), which fall under Biology (a subfield of Natural Science). The questions are fill - in - the - blanks about these biological processes and structures. For example, question 7: Glycolysis takes place in the cytoplasm and breaks down glucose. Question 8: Glycolysis produces pyruvate, $NADH_2$, and 2 ATP molecules. Question 10: There are two types of fermentation that take place in the cytoplasm. Question 11: Alcoholic fermentation occurs in yeast, bacteria, etc. Question 12: Alcoholic fermentation produces ethanol and carbon dioxide. Question 13: Lactic acid fermentation occurs in muscle cells and some bacteria. Question 14: Lactic acid fermentation produces lactic acid, causing muscle soreness. Question 16: After glycolysis, the Krebs cycle occurs. Question 17: The Krebs cycle and electron transport chain take place in the mitochondria. Question 19: In the electron transport chain, hydrogen and oxygen combine to form water and produce about 32 - 34 ATP (the blank here is likely for the number of ATP, and water as waste).

Answer:

The answers to the fill - in - the - blanks (in order of visible questions):

1. cytoplasm; glucose
2. 2
3. fermentation
4. alcoholic
5. ethanol
6. lactic acid
7. lactic acid
8. Krebs
9. mitochondria
10. electron transport chain; 32 - 34; water
