Question

question 1/20 what happens during cellular respiration? a water and carbon dioxide are converted into energy. b glucose is broken down, releasing energy. c oxygen is released into the air. d carbohydrates are released into the bloodstream.

Explanation:

Cellular respiration is a process where glucose is broken - down in the presence of oxygen to release energy, along with water and carbon dioxide as by - products.

Answer:

A. Water and carbon dioxide are converted into energy. (This option is incorrect as water and carbon dioxide are products, not reactants for energy conversion in cellular respiration).
B. Glucose is broken down, releasing energy. (This is correct as glucose is the main molecule broken down during cellular respiration to release energy).
C. Oxygen is released into the air. (This is incorrect as oxygen is consumed, not released, during cellular respiration).
D. Carbohydrates are released into the bloodstream. (This is incorrect as carbohydrates are broken down for energy, not released into the bloodstream during cellular respiration). So the answer is B.
