AP BIO UNIT 3

• The higher the activation energy the slower the chemical reaction will be

  Structure of enzymes:

• Secondary structure: the organization of amino acids (containing of alpha helixes or beta pleated sheets)

• Tertiary Structure: overall 3-demensional part of an enzyme for example the active site or functional groups

  Photosynthesis

  overview:

• Light dependent → inputs: light and h2o, outputs → ATP, NADPH, and o2

• Light independent/calvin cycle → inputs: ATP, NADPH, co2, Outputs → sugar

• Light Dependent:

• Light hits PSII and excites electrons that steal energy from water, the excited electrons move down their free energy level and while doing so release H+ ions, then they hit PSI and do the same process to make NADPH from NADP+ from excited electron transformations and o2 from the h2o being pumped twice without and hydrogen ions.

• Light Independent / calvin cycle

• RUBP catalyzed by Rubisco to make 6 carbon pyruvate than splits into 2 3 carbon molecules in regeneration, then it goes thru 2 times to make 5, 4 stay to make RUBP 1 goes to make glucose
