Photosynthesis Pt 2

Question 1

What does the carbon from CO2 create

Answer 1

Carbohydrates/Glucose

Question 2

What does H2O produce

Answer 2

O2/ Carbon dioxide

Question 3

explain Relationship between light reaction and calvin cycle

Answer 3

The 1-light reaction takes in H2O and creates the by-produce O2 and with that, it creates ATP and NADPH
2- The ATP and NADPH go into the Calvin cycles but the Calvin cycle only takes in 1 phosphate and 1 hydrogen creating ADP and NADP which then get recycled back into the light reaction
3- The 1 phosphate and 1 hydrogen and CO2 together in the calvin cycle then create CH2O/ sugar

Question 4

PSII produces

Answer 4

ATP

Question 5

PSI produces

Answer 5

NADP^+ + H^+

Question 6

What happens in PS II

Answer 6

1-you take away hydrogen from H2O turning it into oxygen
2- Due to breaking those 2 hydrogen bonds 2 electrons are released into PS II
3- The 2 electrons then go into the electron transport chain which then enter PS I
4- The 2 electrons then go and produce NADPH

Question 7

Chemiosmosis

Answer 7

Using the proton motive force to help the enzyme/ ATP synthase to make ATP

Question 8

3 phases of calvin cycle

Answer 8

1- Carbon fixation phase
2- Reduction phase
3- Regeneration phase

Question 9

Carbon fixation phase

Answer 9

1- RuBP/ 5 carbon sugar plus CO2 make PGA/ 3 carbon sugar

Question 10

Reduction phase

Answer 10

1-ATP loses a phosphate then becomes ADP
2-NADPH loses hydrogen and then becomes NADP
3- The one phosphate that was taken from ATP and 3 carbons make G3P

Question 11

Regeneration phase

Answer 11

1- ADP becomes ATP creating the 5 carbon sugar starting the cycle again

Question 12

Antenna

Answer 12

Brings the light in then the light travels through antenna pigment until they reach the reaction center

Question 13

Photons

Answer 13

Excite electrons to travel to the reaction center
