Answer

The molecule depicted in the image is a nucleotide, which is a building block of nucleic acids like DNA and RNA. In the context of energy release for the cell, the nucleotide likely represents adenosine triphosphate (ATP), which is the primary energy carrier in cells.ATP releases energy through a process called hydrolysis, where a phosphate group is removed from the molecule. When one of the phosphate groups (usually the terminal phosphate) is cleaved off, ATP is converted to adenosine diphosphate (ADP) or adenosine monophosphate (AMP) depending on whether one or two phosphate groups are removed, respectively. This reaction releases energy that the cell can use for various functions.Given the options provided:a. Removing the adenine base does not release energy for the cell to use.b. Breaking off a phosphate group is the correct answer, as this is how ATP releases energy.c. Replacing ribose with deoxyribose is a process that does not release energy; it is a structural change that differentiates RNA (which contains ribose) from DNA (which contains deoxyribose).d. Adding a phosphate group is a process that consumes energy, not releases it.Therefore, the correct answer is:b. breaks off a phosphate groupFinal Answer: b. breaks off a phosphate group
