Photosynthesis

Question 1

There are three stages to photosynthesis, name the two that are dependent on light

Answer 1

Light absorption, electron transport chemiosmosis

Question 2

Define light absorption

Answer 2

Light falls on chlorophyll knocking loose a high-energy excited electron

Question 3

What happens in the electron transport chemio osmosis

Answer 3

A. Electrons from the light absorption split H2O making H+ ions + excited electrons +o2
B. These excited electrons react with NDP+ to form NADPH
C. The H+ ions from CYCLE (A) are stored inside chloroplast.
{When the ions are allowed to leak out of the chloroplast through a Channel of protein their stored energy is used to make ATP} (adp+pi +energy make atp)

Question 4

When ADP +Pi get energy from sunlight it becomes?

Answer 4

ATP

Question 5

ATP and NADPH release their energy stored to make

Answer 5

Glucose

Question 6

Carbon fixation process

Answer 6

1. 5 pre-recycled ribose bisphosphate is welded by rubisco with the air we breathe 1 carbon dioxide +oxygen
2. Once they join they split into two groups of three called phosphoglycerides or PGAs
3. Nicotinamide adenine tide phosphate or NADPH Burns its energy and becomes NADP+ to attach one hydrogen to each GPA {making them a new molecule called glyceraldehyde three phosphates or G3ps}
4. Meanwhile ATP gives them energy and lubricant by burning its energy and becoming ADP+Pi
5. 6 of these processes happen at the same time each of them make 2PGAs in total they make 12 PGAs in total 36 single carbons.
6. 2 of the total 12 pga’s make glucose + 10 of the 10 left are recycled to fuel the next production of glucose

Question 7

Carbon fixation or. Calvin cycle molecular formula

Answer 7

6(5-c) + 6 (6-c) +12 PGA>

12PGA~2 glucose
12PGA~10 PGA recycled back to 6(5-c)
