6. Photosynthesis Flashcards
What are the reactants required to conduct photosynthesis?
Carbon Dioxide and Water
Light-absorbing pigments in plant cells
Chlorophyll
What defines the purpose of light in the process of photosynthesis?
Light excites electrons to be incorporated in pigment molecules
What are the two chlorophyll A molecules used in photosynthesis?
P680 and P700
The porphyrin ring in Chlorophyll A is centrally bound to which atom?
Magnesium
What kind of energy drives photosynthesis?
Light Energy
Where is energy stored at the end of photosynthesis?
The chemical bonds of glucose
What is the difference between chlorophyll and heme?
Chlorophyll porphyrin is complexed with Mg whereas heme porphyrin is complexed with Fe
Membrane-bound spaces in the chloroplast where only light-dependent reactions take place
Thylakoids
What does a stack of thylakoids form?
Granum
Where in the chloroplast do protons build up due to the electron transport chain?
Thylakoid Lumen
What in plant cells is analogous to the cytosol in animal cells?
Stroma
Aqueous component of the animal cell AND plant cell, respectively
Cytosol and Stroma
Class of photoreceptors found in plants, fungi, and baceteria
Phytochromes
Where in the chloroplast does the Calvin Cycle take place?
Stroma
