Question

The molecule shown here is commonly used for energy to do cell work. A student measures the cellular contents over time and notices the cell is showing an increase in this molecule. What hypothesis is supported by the evidence that this molecule is increasing within the cell? A) As thermal energy is absorbed, ATP levels will increase. B) As photosynthesis occurs in the cell, ADP levels will increase. C) As cellular respiration occurs in the cell, ATP levels will increase. D) As cellular respiration occurs in the cell, ADP levels will increase.

Answer 1

C) As cellular respiration occurs in the cell, ATP levels will increase.

Step-by-step explanation:

Cellular respiration is the process of generation of ATPs. This occurs through glycolytic pathways, Kreb's cycle,and primarily by oxidative phosphorylation. Therefore as cellular respiration occurs in the cell, the currency of energy to do work ATPs will continue to be synthesized by the ATPase synthase in the matrix of the mitochondria,to supply enough energy to meet up with the biological work in the cells.

Therefore the higher the rate of cellular respiration, the higher the amount of ATPs production in the cells,since the molecule for energy to do cell work is ATPs, produced by cellular respiration.

Answer 2

C) As cellular respiration occurs in the cell, ATP levels will increase.

Step-by-step explanation:

Firstly, the molecule described in the question is Adenosine triphosphate (ATP). It is the energy currency in living cells. It is the usable form of energy to do work/activities by the cell. Ideally, the process by which all living organisms acquire this molecule (ATP) is called CELLULAR RESPIRATION.

Cellular respiration is the process by which living organisms break down food (organic molecule) to produce energy in form of ATP. This is why there is a saying that "Organisms eat to obtain energy". The food eaten is actually broken down in order to release the stored energy in it.

Hence, a cell that is increasing in ATP (energy) content means that cellular respiration is being undergone in that cell.
