Final answer:
The hydrolysis of ATP powers numerous cellular functions, including active transport and cell division. Among the options provided, the digestion of sucrose is a catabolic process because it breaks down complex molecules into simpler ones.
Step-by-step explanation:
The hydrolysis of ATP releases energy that is essential for several cellular processes beyond those listed in Model 3. Two additional processes that are fueled by the hydrolysis of ATP are active transport and cell division.
Active transport is the movement of molecules across a cell membrane from an area of lower concentration to an area of higher concentration, requiring energy to go against the concentration gradient. Cell division, which includes both mitosis and cytokinesis, also relies on ATP to orchestrate the complex rearrangements and movements necessary for one cell to split into two.
Regarding question 4, the catabolic process among the options provided is a. digestion of sucrose, as this process involves breaking down a complex molecule into simpler ones, releasing energy in the process.
