- C.
  
  Glucose
- D.
  
  Starch
2.

What is the function of water in photosynthesis?
- A.
  
  Provides oxygen
- B.
  
  Provides hydrogen and electrons
- C.
  
  Allows enzymes absorb carbon dioxide
3.

In stage 1 of photosynthesis, blank is captured from sunlight.
4.

In stage 2 of photosynthesis, light energy is converted to chemical energy which is temporarily stored in blank and the energy carrier molecule blank. Put comma between answers.
5.

Many molecules that participate in photosynthesis are embedded in the blanks. (hint: its two words)
6.

In stage 3 of photosynthesis, the chemical energy stored in the blank and blank, powers the formation of blank compounds, using blank.
7.

The series of molecules through which excited electrons are passed along the thylakoid membrane are called blanks.
8.

Some electron transport chains contain a blank that acts as a membrane pump. Excited electrons that pass through this pump blank some of their energy, but that energy is later used to pump blank ions into the thylakoid.
