16
Q

What are the stages of photosynthesis

A

the light-dependent reactions and the Calvin cycle.

17
Q

where does the light-dependent stage occur

A

Occurs in the granum
specifically the thylakoid membrane.

18
Q

what are the thylakoid membrane parts

A

PS1
PS2
ETC
ATP synthase

19
Q

what is the process of photosynthesis (light-dependent reactions)

A
  1. Electrons get excited by sunlight in PSII making chlorophyll
  2. The excited electrons travel through the ETC
  3. Electrons lost in the chlorophyll of Photosystem II is replaced with the help of the process called “photolysis”.
  4. ETC transports electrons while the energy in electrons is used to pump hydrogen ions into the thylakoid creating a high concentration inside in the thylakoid
  5. When electrons reached the end of the first ETC, they go to photosystem I where light excites them once again.
  6. They travel down the second ETC where they finally get accepted by a molecule called NADP+.
  7. When NADP+ accepts electrons, it also accepts hydrogen forming NADPH.
  8. The high concentration of hydrogen ions inside the thylakoid is passively diffused by a protein called ATP Synthase. During this process, ATP synthase converts ADP into ATP adding one more phosphate group to its chain
20
Q

What are the products of light dependent reaction

A

ATP
NADPH
O2
