Photosynthesis & Cellular Respiration Flashcards
formula for photosynthesis
CO2+H20=(light energy and chlorophyll) C6H1206 + O2
3 photosynthetic pigments and the colour they give off
chlorophyll(green), carotene (yellow , orange), phycocyanin (blue), phycoerythrin (red), xanthophyll (yellow, orange)
what are the products of light dependent reactions
ATP , NADPH
what happens in the Calvin cycle
carbohydrates are synthesized using carbon dioxide
phosphorylation
addition of a phosphate group
how much ATP and NADPH is needed in the Calvin cycle to produce 1 molecule glucose
18 ATP, 12 NADPH
how much carbon does PGA have
3
what are the steps involved in the Calvin cycle
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
formula for cellular respiration
C6H12O6+ O2= CO2 + H2O+ 36 ATP
chemiosmosis
movement of ions through a semi permeable membrane to form ATP
fate of glucose
starch cellulose sucrose
cellular respiration
chemical reactions that provide energy for life
what are the final products of Krebs cycle
CO2 H20
4 electron carriers found in the mitochondrion
NAD, FAD, FMN, oxygen
where does glycolysis occur
cytoplasm
end product of glycolysis
pyruvate or pyruvic acid
net gain of ATP in glycolysis
2
total gain of ATP in glycolysis
4
fate of pyruvate
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
what happens to Acetyl CoA
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
