background image Unit 3 Study Guide Ch. 7, 8, & 9 End of Chapter 7 – Questions 1. What is photosynthesis?
2. Does photosynthesis occur in autotrophs or heterotrophs?
3. Where in the cell does photosynthesis happen?
4. What are the 3 key locations in which photosynthesis occurs?
5. Where is the light energy harvested and converted into energy 
intermediates? 6. What are the products of light reactions?
7. What is light?
8. True or False, energy carried by photons can be transferred to 
electrons. 9. Can chlorophyll absorb light energy?
10.
What are the 2 parts of Photosystem II? 11. True or False, electrons never lose energy when being passed  around. 12. Describe Photosystem I. 13. Name what is happening in this picture. 14. What are the 3 phases of the Calvin cycle/ dark reactions? 15. Describe the 3 phases. End of Chapter 7 – Answers 1. The process by which the energy within light is captured and used to  synthesize carbohydrates. 2. Autotrophs, organisms that make organic molecules from inorganic  sources. 3. In the chloroplast.
4. Stroma, thylakoid membrane, and thylakoid lumen.
5. In the thylakoid membrane.
6. O
2 , energy intermediates: ATP & NADPH 7. Electromagnetic radiation carrying from the Sun.
8. True, photons bump into electron and transfers the energy.
background image 9. Yes, it has electrons that can be photo-excited.
10.
The light harvesting complex and the reaction center 11. False, electrons DO lose energy every time that they are passed  around. 12. Electrons work their way to photosystem I from cytochrome  complex, another photon joins chlorophyll, and eventually the electron 
gets photo-excited.
13. NADP reductase. 14. Carbon fixation, reduction and carbohydrate production,  regeneration of ribulose bisphosphate 15. Carbon fixation: CO 2  is added to ribulose bisphosphate and the 6 carbon molecule is then split into two 3 carbon molecules.
Reduction and carbohydrate production: add electrons and NADPH & 
ATP as reactants, generates carbohydrate intermediates.
Regeneration of ribulose bisphosphate: convert the 3 carbon 
intermediate back into ribulose bisphosphate.
Chapter 9 – Questions 1. Define cell communication and explain what it does.
2. What are signals and give examples?
3. What are receptors?
4. What are the 4 types of cell-to-cell communication?
5. Describe each type of cell-to-cell communication.
6. Describe the 3 steps to the process of responding to signals?
7. What is a ligand?
8. True or False, many ligands are hydrophilic so they bind to integral 
membrane receptors. 9. Describe the 4 types of cell surface receptors?
10.
What is the role of second messengers? 11. What are some of the specific differences in signal transduction  via cyclic adenosine monophosphate? 12. True or False, the effects of the ligand are independent of the  receptor and the proteins inside the cell. Chapter 9 – Answers 1. The process by which cells can detect and respond to certain signals in the extracellular environment. Within multicellular organisms it helps 
coordinate organism-wide processes.
2. Anything that can influence the properties of cells. Light, touch,  temperature, or chemicals. 3. Specialized cellular proteins that respond to signals with a  conformational change. 4. Contact-dependent signaling, autocrine signaling, paracrine signaling,  and endocrine signaling.
