Exam 1 - Photosynthesis Wrap-Up Worksheet Flashcards
1
Q
When given a graph of absorbance vs. wavelength, which wavelengths are contributing to photosynthesis and which are not?
A
- wavelengths with high absorbance highly contribute to photosynthesis
- wavelengths with low absorbance barely contribute to photosynthesis
2
Q
How can you tell which wavelengths are absorbed by a plant versus which are reflected?
A
reflected wavelengths will be the color(s) of the plant; all others are absorbed
3
Q
What is the function of the pigment molecules in a light-harvesting complex in the thylakoid membranes?
A
absorb and transfer light energy to the reaction-center chlorophyll
4
Q
What are the product(s) of cyclic electron flow?
A
ATP
5
Q
Why are C4 plants able to photosynthesize with no apparent photorespiration?
A
they use PEP carboxylase to initially fix CO2
6
Q
What are the metabolic results of photorespiration?
A
produces carbon dioxide, consumes ATP and oxygen
