8. glucose and oxygen are the ______ of cellular respiration
9. the krebs cycle takes place in this part of the mitochondria
10. the number of carbon dioxide or water molecules produced by 1 molecule of glucose during cellular respiration

Explanation:

This is a crossword puzzle about cellular respiration, which falls under Biology (a subfield of Natural Science). Let's solve some clues:

Across 5: Products of cellular respiration are water and carbon dioxide. So the answer is "carbon dioxide".

Across 6: The step where acetyl - CoA is transformed and CO₂ is released is the Krebs cycle (Citric Acid Cycle).

Across 7: The electron transport chain occurs in the inner mitochondrial membrane.

Across 8: Alcoholic fermentation produces alcohol and CO₂.

Across 10: Anaerobic respiration (fermentation) is used in food production (like making bread, yogurt).

Across 12: Glycolysis is the anaerobic first step of cellular respiration.

Across 13: ATP (Adenosine Triphosphate) is the energy currency of the cell.

Across 16: Lactic acid fermentation occurs in animal cells without oxygen.

Across 18: Anaerobic respiration occurs without oxygen.

Down 1: The electron transport chain produces the most ATP in respiration.

Down 2: Water and carbon dioxide are products of cellular respiration.

Down 3: Glycolysis produces 2 ATP molecules (net).

Down 4: Aerobic respiration occurs with oxygen.

Down 9: Glycolysis occurs in the cytoplasm.

Down 11: Oxygen (O₂) is the gaseous reactant of cellular respiration.

Down 12: Glucose is broken down in glycolysis.

Down 14: Glucose and oxygen are reactants of cellular respiration.

Down 15: The Krebs cycle occurs in the mitochondrial matrix.

Down 17: 1 molecule of glucose produces 6 CO₂ and 6 H₂O in cellular respiration (from the equation \(C_6H_{12}O_6 + 6O_2
ightarrow6CO_2 + 6H_2O+ ATP\)).
