Which form of chemical reaction is responsible for converting a molecule of ADP to ATP? A) hydrolysis B) dephosphorylation C) phosphorylation D) glycolytic reaction

The following image depicts a cellular process which is essential for providing genetic diversity in sexually reproducing organisms. What cellular process is shown below? A) Anaphase B) Crossing over C) Apoptosis D) Binary Fission

The addition of heat is the best way to speed up chemical reactions in cells because it speeds up the movement of molecules in the cell.
