Photosynthesis & Cellular Respiration

Question 1

formula for photosynthesis

Answer 1

CO2+H20=(light energy and chlorophyll) C6H1206 + O2

Question 2

3 photosynthetic pigments and the colour they give off

Answer 2

chlorophyll(green), carotene (yellow , orange), phycocyanin (blue), phycoerythrin (red), xanthophyll (yellow, orange)

Question 3

what are the products of light dependent reactions

Answer 3

ATP , NADPH

Question 4

what happens in the Calvin cycle

Answer 4

carbohydrates are synthesized using carbon dioxide

Question 5

phosphorylation

Answer 5

addition of a phosphate group

Question 6

how much ATP and NADPH is needed in the Calvin cycle to produce 1 molecule glucose

Answer 6

18 ATP, 12 NADPH

Question 7

how much carbon does PGA have

Answer 7

3

Question 8

what are the steps involved in the Calvin cycle

Answer 8

CO2 reacts with a 5 carbon molecule, RBP (CO2 acceptor) which forms 2 molecules of PGA with the help of an enzyme Rubisco. PGA is activated with the 18 ATP and is reduced with the NADPH. The 2 molecules of PGAL are then used to form glucose. the rest is used to make RBP

Question 9

formula for cellular respiration

Answer 9

C6H12O6+ O2= CO2 + H2O+ 36 ATP

Question 10

chemiosmosis

Answer 10

movement of ions through a semi permeable membrane to form ATP

Question 11

fate of glucose

Answer 11

starch cellulose sucrose

Question 12

cellular respiration

Answer 12

chemical reactions that provide energy for life

Question 13

what are the final products of Krebs cycle

Answer 13

CO2 H20

Question 14

4 electron carriers found in the mitochondrion

Answer 14

NAD, FAD, FMN, oxygen

Question 15

where does glycolysis occur

Answer 15

cytoplasm

Question 16

end product of glycolysis

Answer 16

pyruvate or pyruvic acid

Question 17

net gain of ATP in glycolysis

Answer 17

2

Question 18

total gain of ATP in glycolysis

Answer 18

4

Question 19

fate of pyruvate

Answer 19

if there’s oxygen, it’s oxidized in the mitochondria and turned into Acetyl CoA. If there isn’t oxygen it stays in the cytoplasm and fermentation occurs forming ethyl alcohol or lactic acid

Question 20

what happens to Acetyl CoA

Answer 20

it’s oxidized in the kreb’s cycle till it forms into electron acceptors like NADH. These molecules supply high energy electrons in a electron transport system which forms large amounts of ATP
