       A plant has a unique photosynthetic plagment. The leaves of this plant appear to be reddish yellow, What wavelengths of visible light are being absorbed by this pigment?  Red and yellow  blue and violet  green and yellow  blue, green, and red  green, blue, and yellow  What is the source of the oxygen produced during photosynthesis?  ambient air  CO_2  chlorophyll oxidation  H_2_O  carbohydrate 
  
  Solution
21. E. 1000
pH=-log[H+], change in 3 units corresponds to 1000 times higher H+
22.A. an amphipathic pigment molecule
Chlorophyll pigment has a tetrapyrrole ring system (hydrophilic portion) and a hydrophobic (fat soluble) phytol chain
23.C inner mitochondrial membrane
24.B. Blue and violet
Chlorophyll is green is because it absorbs other colors of light such as red and blue, so in a way the green light is reflected out since the pigment does not absorb it.
25. D. H2O
Splitting of H2O is the source of oxygen
