Chapter 5, Problem 3PIT
Summary Introduction
To determine:
The relationship among chloroplast, grana, stroma, thylakoids, photosystems, and chlorophyll via a concept map.
Concept introduction:
Chloroplasts are referred as “the site of photosynthesis”. These are the organelles where photosynthesis takes place in a plant cell. It consists of grana and stroma. Grana are the region where the light reaction takes place, whereas stroma is the region where the dark reaction of photosynthesis takes place.

- 1.Which of the following best describes how light energy is "captured" during the process of photosynthesis? a. The correct photon of light "excites" an electron in a chlorophyll molecule. b. Light heats up the stroma in the center of the chloroplast which causes enzymes to convert CO2 into glucose. c. Photons of light cause H+ to move through the thylakoid membrane, creating a hydrogen ion gradient. 2. What best explains what happens to the electrons that are excited out of chlorophyll molecules during the process of photosynthesis? a.They are pumped across the thylakoid membrane in the ETC of photosynthesis. b. They cause electrons in NADPH to get "excited" and form new bonds in ATP. c. They are captured and move through an ETC, creating ATP and ultimately being captured by NADPH. d. They fall back into the chlorophyll molecule, emitting ATP as they fall.arrow_forward1.
