Question

Together, the stages of cellular respiration break down one molecule of (lactic acid / fatty acids / protein / glucose) into a total of (4 / 36 / 12 / 72) molecules of ATP. The remaining energy is released as (light / heat / motion).

Answer 1

The correct answer is: glucose, 36, and heat.

Step-by-step explanation:

In the cellular respiration, there are three steps or stage that breaks the glucose molecule into pyruvate and then release carbon dioxide and water with forming a high amount of energy in the form of ATP. The total amount of energy that produces in the process are:

Glycolysis: 2 ATP

Kreb's cycle: 2 ATP

ETC: 32 - 34 ATP

The remaining energy that produces in the process is lost as heat almost 60% of the total energy.
