Write out the three factors that affect photosynthesis.

write out the formula of photosynthesis in both words and symbols.

Reorder the process of ATP synthesis.

• The electron transport chain uses energy lost by the high energy electrons to pump the H+ ions into the thylakoid space

• PSII absorbs light and changes the low energy electrons into high energy electrons.  

• electrons from water molecules flow to the photosystem II.

• High energy electrons go through the electrons transport chain.

• The H+ ions escape through the ATP synthase. 1.      The ATP synthase rotates as the H pass through. When the ATP rotates, ADP converts to ATP.

Reorder the process of NADPH synthesis.

• The low energy electrons get energy in photosystem I and become high-energy electrons again.

• The high energy electrons lost energy to the electron transport chain and become low energy electrons.

• The high energy electrons combine with the NADP+ and become NADPH.

Match the following

• one of the molecules that accepts high-energy electrons

  from chlorophyll and carries them to other

• Stroma

• a reaction of photosynthesis that

  uses light energy to make ATP and

  NADPH.

• Thylakoid

• a baglike photosynthetic membrane found in chloroplasts.

• NADP+

• a reaction of photosynthesis that

  uses ATP, NADPH, and carbon

  dioxide to make high-energy

  sugars.

• Light-dependent reaction

• the liquid-filled space surrounding the thylakoids in chloroplasts.

• Light-independent reaction

Match the following

• the light-collecting units of the chloroplast.

• Photosystem

• one of the molecules that accepts high-energy electrons

  from chlorophyll and carries them to other

• Electron transport chain

• a series of proteins in which

  high-energy electrons are used to change ADP to ATP.

• NADP+
