Question

Identify whether each item is a reactant or a product of cellular respiration

Answer 1

Answer:

Glucose is a reactant of cellular respiration.

Carbon dioxide and water are both products if cellular respiration.

Note: The question is incomplete. The complete question is given below:

Identify whether each item is a reactant or a product of cellular respiration. glucose carbon dioxide (co2) water (h2o)

Explanation:

Cellular respiration is the process by which glucose is broken down by the cells to produce the energy molecules, ATP.

The various reaction steps of cellular respiration include glycolysis- where glucose is broken down into two molecules of pyruvate, the citric acid cycle- where two acetylCoA molecules produced from the oxidation of pyruvate are converted to carbon dioxide molecules, and finally the electron transport chain- where the electron-donors NADH and FADH2 produced in the citric acid cycle donate their electrons to oxygen to produce water molecules.

The overall chemical reaction for cellular respiration is represented as follows:

C6H12O6 + 6O2 → 6CO2 + 6H2O

1 molecule of glucose reacts with six molecules of oxygen to produce six molecules of carbon dioxide and six molecules of water.

Therefore, glucose is a reactant while carbon dioxide and water are both products of cellular respiration.

Answer 2

Answer:

Identify whether each item is a reactant or a product of cellular respiration.  

✔ reactant   glucose  

✔ product    carbon dioxide (CO2)  

✔ product    water (H2O)

Place the three stages of aerobic cellular respiration in the correct order from 1 to 3.  

✔ 3    electron transport chain  

✔ 1      glycolysis    

✔ 2    citric acid cycle
