Explanation:

Step1: Recall cellular respiration basics

Cellular respiration converts glucose into energy. So the answer for 1 is glucose.

Step2: Identify the organelle

Mitochondria is the organelle associated with cellular respiration, answer for 2.

Step3: Write the chemical - equation products

The chemical equation for cellular respiration is Glucose + Oxygen -> Carbon dioxide + Water+ ATP. So answers for 3 are carbon dioxide and water.

Step4: Fill in the blanks for glycolysis

During glycolysis, a molecule of glucose is broken down into two molecules of pyruvate. Answer for 6 is pyruvate.

Step5: Complete the blanks for stages

The first stage of cellular respiration is glycolysis, second is the Krebs cycle, third is the electron transport chain. Answers for 10 - 12 are glycolysis, Krebs cycle, electron respectively.

Step6: Identify the phosphorylation type

The majority of ATP is produced in the third stage through oxidative phosphorylation. Answer for 13 is oxidative.

Step7: Glycolysis location and products

In eukaryotes, glycolysis happens in the cytoplasm. In prokaryotes, it happens in the cytosol. The starting molecule is glucose and the end - products are 2 pyruvate, 2 ATP, 2 NADH.

Answer:

1. Glucose
2. Mitochondria
3. Carbon dioxide, Water
4. ATP
5. Oxygen
6. Pyruvate
7. Fermentation
8. Ethanol
9. Lactic acid
10. Glycolysis
11. Krebs cycle
12. Electron
13. Oxidative
14. Synthase

Glycolysis:
Happens in cytoplasm in eukaryotes
Happens in cytosol in prokaryotes
Starting molecule: Glucose
End products: Pyruvate, ATP, NADH (2 of each)
