Question
In the thylakoid membranes, what is the main role of the antenna pigment molecules? A) split water and release oxygen to the reaction-center chlorophyll B) harvest photons and transfer light energy to the reaction-center C) synthesize ATP from ADP and i D) transfer electrons to ferredoxin and then NADPH E) concentrate photons within the stroma In a plant cell, where are the ATP synthase complexes located? A) thylakoid membrane only B) plasma membrane only C) inner mitochondrial membrane only D) thylakoid membrane and inner mitochondrial membrane E) thylakoid membrane and plasma membrane Where are the molecules of the electron transport chain found in plant cells? A) thylakoid membranes of chloroplasts B) stroma of chloroplasts C) outer membrane of mitochondria D) matrix of mitochondria E) cytoplasm Where do the enzymatic reactions of the Calvin cycle take place? A) stroma of the chloroplast B) thylakoid membranes C) matrix of the mitochondria D) cytosol around the chloroplast E) thylakoid space What is the primary function of the Calvin cycle? A) use ATP to release carbon dioxide B) use NADPH to release carbon dioxide C) split water and release oxygen D) transport RuBP out of the chloroplast E) synthesize simple sugars from carbon dioxide Reactions that require CO_2 take place in A) the light reactions alone. B) the Calvin cycle alone. C) both the light reactions and the Calvin cycle. D) neither the light reactions nor the Calvin cycle. E) the chloroplast, but is not part of photosynthesis Which of the following sequences correctly represents the flow of electrons during photosynthesis? A) NADPH rightarrow O_2 rightarrow CO_2Explanation / Answer
18) the correct answer is (B). The antenna in the thylakoid membrane is also called light harvesting complex. It is made up of protein and chlorophyll. Mainly chlorophyll b and carotenoids. This antenna traps the light energy and transfer to core pigment (chlorophyll a).
