Light Dependant Reactions

What are Light Dependant Reactions?

the initial phase of photosynthesis, converting light energy into chemical energy in the form of ATP and NADPH

Where do LDR occur?

In the Thylakoid

Step 1

Sunlight hits electrons exciting them, causing the electrons to orbit photosystem ll and spin faster.

Step 2

Photolysis occurs, breaking H2O to oxidize it by using light energy

Step 3

Electrons from H2O are transported through electron carriers in the thylakoid membrane to NADP+, causing it to reduce
