- Q1What are the 3 parts of an ATP molecule?stroma, grana, and chlorophylladenine, ribose, and 3 phosphate groupsNADH, NADPH, AND FADH2adenine, thylakoid, and a phosphate group30s
- Q2A granum is amembrance enclosing a thylakoidstack of chloroplastsstack of thylakoidsphotosynthetic pigment molecule30s
- Q3Why are electron carriers needed for transporting electrons from one part of the chloroplast to another?High-energy electrons get their energy from electron carriers.High-energy electrons are highly reactive.High-energy electrons are not soluble in cytoplasm.High-energy electrons would be destroyed.30s
- Q4Which chemical is an electron carrier molecule?oxygencarbon dioxideNADP+a. H2O30s
- Q5Why might the candle in jar A burn longer than the candle in jar B?Chlorophyll produced by the plant allows the candle to burn longer.Oxygen produced by the plant allows the candle to burn longer.Carbon dioxide produced by the plant allows the candle to burn longerGlucose produced by the plant allows the candle to burn longer.30s
- Q6Where do the light-dependent reactions take place?in the outer membrane of the chloroplastswithin the mitochondria membranesin the stroma of the chloroplastwithin the thylakoid membranes30s
- Q7What action contributes to the inside of the thylakoid membrane becoming positively charged during the light-dependent reactions?ATP synthase allows H+ ions to pass through the membrane.Carbon dioxide builds up in the stromaH+ ions are released as water splits.ATP synthase produces ATP from ADP.30s
- Q8The Calvin cycle takes place in thechlorophyll molecules.photosystems.thylakoid membranes.stroma.30s
- Q9Which molecule is recycled between the Calvin cycle and the light-dependent reactions during photosynthesis?Carbon dioxideWaterOxygenADP30s
- Q10Hydrogen ions are important in the light-dependent reactions of photosynthesis because they produce a difference in charge across the thylakoid membrane that allowsthe production of ATP.the conversion of 3-carbon molecules into higher-energy forms.the release of water molecules.light to enter the chloroplast.30s
- Q11What is the role of carbon dioxide in the Calvin cycle?It is used to move high-energy electrons down the electron transport chain.It uses energy from ATP and reduces the molecule to ADP.It combines with 5-carbon compounds and is converted into high-energy sugars.It is used by pigments in the chloroplasts to absorb sunlight.30s
- Q12Plants need carbon dioxide from their environment to produce glucose during which stage of photosynthesis?ATP formationThe light-dependent stageThe light-independent stageThe electron transport chain30s
- Q13Which of the following equations represents the process of photosynthesis?Carbon dioxide + Sugars Water + Oxygen6 CO2 + 6 H2O C6H12O6 + 6 O2Sugars + Oxygen Carbon dioxide + WaterC6H12O6 + H2O CO230s
- Q14How many sugar molecules are produced from every six molecules of carbon dioxide that enter the Calvin cycle?1312630s
- Q15What compound do cells use to store and release energy?WaterChlorophyllATPCarbon dioxide30s
