_______________________ is a process that uses light energy to drive an electron transport chain to make ATP.

There are three mechanisms for the phosphorylation of ADP to produce ATP. Write the name of the mechanism that describes each of the reactions in the following table.

<IMAGE>

All of the energy-producing biochemical reactions that occur in cells, such as photophosphorylation and glycolysis, are ________ reactions.

Why is the phosphorus cycle important?

_______________________ is a process that relies on a phosphorylated intermediate to directly convert ADP to ATP.

_______________________ is a process that uses energy from nutrients to fuel an electron transport chain to make ATP.
