Question

Energy extraction and the complete oxidation of foodstuffs requires three stages. The energy extracted from fuels is converted to ATP.
Select the statements that are true for the different stages required for energy extraction and complete oxidation of foodstuffs. In the first and second stages the majority of ATP needed for cellular processes is produced.

a. In the third stage, fuel molecules are completely oxidized to CO2, and a small amount of ATP is produced.
b. In the third stage, fuel molecules are completely oxidized to CO2, and most of the ATP needed for cellular processes is produced.
c. In the third stage, fuel molecules are completely oxidized to CO2, and no ATP is produced.
d. In the first stage, macromolecules are converted to monomers, and a small amount of ATP is produced.
e. In the second stage, monomers are broken down, and a small amount of ATP is produced.

Answer 1

Note: Question lack some information i have added full question with answer as picture. see attachment.

Answer:

d. In the first stage, macro-molecules are converted to monomers, and a small amount of ATP is produced.

e. In the second stage, monomers are broken down, and a small amount of ATP is produced.

c. In the third stage, fuel molecules are completely oxidized to CO2, and no ATP is produced.

Explanation:

When we take food a process starts which is called as cellular respiration. Through this process the food energy is converted into cellular energy which will further used by body. During all this process oxygen and glucose are converted into water and carbon dioxide and energy in this process is converted into ATP.
