1. What is the function of light in the light-depedent reaction?
- To make ATP, photolysis of water, to excite an electron in chlorophyll
- To reduce CO2, to make ATP, to excite an electron in chlorophyll
- photolysis of water, to reduce glycerate-3-phospate, to make ATP
- To make ATP, photolysis of water, To enable the chlorophyll to take up an electron
