Put the following steps in correct order from the start of photosynthesis to the end of photosynthesis. Place your cursor on the selection to move it intothe right place in the sequence.
High energy electrons move to NADP reductase to make NADPH
Sunlight excites electrons in PS II
3 more CO2 enter the Calvin cycle, produce the 2nd G3P and a glucose molecule is made
High energy electrons move across the electron transport chain and pump hydrogen ions against the concentration gradient to the inside of the thylakoid space.
6 ATP and 6 NADPH are used to reduce 3 carbon molecules into 6 G3Ps
5 G3P are reduced using 3 ATP to make RuBP
1 G3P exits the Calvin cycle to make part of the glucose molecule
Hydrogen ions move down the concentration gradient and diffuse through ATP synthase to make ATP
Water is split and electrons replace the electrons that exited PS II in a process called photolysis
Sunlight excites electrons in PS I
3 carbon dioxides from the atmosphere enter the Calvin cycle by attaching to RuBP and the enzyme rubisco and undergo fixation.
Low energy electrons from PS II move to PS I to replace electrons that exited after they were excited.
ATP and NADPH enter the Calvin cycle to be used in reduction phase
