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
