Question

In cellular respiration, approximately 38% of the energy contained in glucose is released for an organism to use in carrying out life processes. Which best explains what happens to the remaining 62% of the energy contained in glucose?

Answer 1

Answer:

This question lacks options, the options are:

A) The energy is used to start the process of cellular respiratoin when more glucose is consumed by the organism

B) The energy is used to convert leftover glucose into protein to be stored by the cells of the organism

C) The energy is stored by the cells and released later when needed by the organism

D) The energy is converted to thermal energy, which provides heat to the organism.

The answer is D

Explanation:

The process of cellular respiration is the way living organisms obtain their energy for use. During cellular respiration, glucose molecules (derived from ingested/digested food) is broken down in a series of chemical reactions to yield ATP, which is the usable form of energy by cells.

However, only a little fraction of the synthesized energy during respiration (approximately 38% as stated in this question) is used by organisms to carry out their cellular functions. A majority of the energy (about 62%) is LOST as HEAT or THERMAL ENERGY. The heat or thermal energy produced during metabolic activities helps keep the organisms warm.

Answer 2

The given question is incomplete as it lacks options, however, the correct choices are as follows:

• A) The energy is used to start the process of cellular respiration when more glucose is consumed by the organism  
• B) The energy is used to convert leftover glucose into protein to be stored by the cells of the organism  
• C) The energy is stored by the cells and released later when needed by the organism  
• D) The energy is converted to thermal energy, which provides heat to the organism.

The best explains what happens to the remaining 62% of the energy contained in glucose - D) The energy is converted to thermal energy, which provides heat to the organism.

Cellular respiration is the catabolic process that takes place in every organism in order to produce energy in the form of ATP by breaking down the glucose molecules.

• approximately 38% of total energy synthesized, is used by organisms to carry out their cellular functions.

• A majority of the energy synthesized is lost to the environment as heat or thermal energy.
• This energy is generated when the various metabolic process takes place that helps keep the organisms warm.

Thus, The best explains what happens to the remaining 62% of the energy contained in glucose - D).
