Photosynthesis Notes Continued:

 

What are the 2 types of reactions in photosynthesis?

1. The first reaction is called Light-Dependent (occurs in the thylakoids).

 

Note:  Light-Dependent- needs sunlight

 

2. The second reaction is Light- Independent(occurs in the stroma).

 

Note: Light-Independent- Alone; by itself; Light –independent- doesn’t need sunlight. The 2nd reaction does not need sunlight. The reaction can happen without light. 

 

What do electron carriers do?

Sunlight makes electrons in the chlorophyll (located in the thylakoids) very excited!

 

What does the NADPH do?

The NADPH carries the very excited high-energy electrons to reactions in the cell.

 

Cycle?

The Calvin Cycle uses ATP and NADPH from light-dependent reactions to produce high-energy sugars (FOOD)
