Froggy Jumps Cell Energy IV Lowersixth Science BiologyVersion en ligne Challenging biology questions for 17-year-olds par YAKILI LMS 1 What primarily distinguishes absorption spectra from action spectra? a Absorption spectra relate to enzyme activity; action spectra relate to chlorophyll quantity. b Absorption spectra show pigment light absorption; action spectra show photosynthetic rate vs wavelen c Absorption spectra measure energy release; action spectra measure pigment color. 2 Which statement about absorption spectra is true? a They show the rate of respiration at different wavelengths. b They measure the rate of photosynthesis directly. c They plot how much light a pigment absorbs at each wavelength. 3 Which statement about action spectra is true? a They plot the rate of photosynthesis at different wavelengths. b They plot pigment concentration by wavelength. c They show adsorption of pigments on chromatography paper. 4 Which component is essential for chromatography to separate pigments? a Only a mobile phase b Only a stationary phase c A mobile phase and stationary phase 5 What is chromatographic paper primarily made of? a Protein matrix b Cotton fibers c Cellulose fibers 6 Which factor mainly affects chromatogram movement of pigments? a Paper thickness only b Ambient temperature only c Solvent polarity and pigment solubility 7 What is a chromatogram? a A record of separated substances on a chromatography medium b A device to measure light intensity c A type of genetic sequence 8 What does the Retention Factor (Rf) measure? a Light absorbance of pigment b Distance moved by pigment divided by solvent front distance c Rate of photosynthesis 9 Which equation defines Rf in chromatography? a Rf = pigment intensity / exposure time b Rf = distance travelled by substance / distance travelled by solvent front c Rf = pigment mass / solvent volume 10 Which statement about chromatography is correct? a Different pigments travel at different rates due to solubility and interactions b All pigments move the same distance c Only one pigment can be separated 11 In photosynthesis, what is the role of pigment excitation by light? a Destroys chlorophyll molecules b Inhibits electron flow c Excites electrons to higher energy levels enabling energy transfer 12 Which process converts light energy to chemical energy in photosynthesis? a Photophosphorylation and carbon fixation coupling b Oxidation of glucose c Fermentation 13 Which pigment is primarily involved in capturing light energy? a Hemoglobin b Carotene only c Chlorophyll a 14 What is the primary site of photosynthesis in plants? a Mitochondria in root cells b Nucleus of leaf cells c Chloroplasts in leaf mesophyll cells 15 What happens during light-dependent reactions? a Glucose is produced directly b Water is split and ATP/NADPH are produced c Oxygen is consumed to fuel reactions 16 Which gas is released during the light-dependent reaction? a Nitrogen gas b Oxygen c Carbon dioxide 17 Where does the light-dependent reaction occur? a Stroma only b Mitochondrial matrix c Thylakoid membranes of chloroplasts 18 What pigment primarily absorbs red and blue light for photosynthesis? a Chlorophyll b only b Carotenoids only c Chlorophyll a 19 Which process fixes CO2 into organic molecules? a Glycolysis b Krebs cycle c Calvin cycle (light-independent reactions) 20 Which enzyme catalyzes the first CO2 fixation in C3 plants? a ATP synthase b Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) c Photosystem II 21 What is the main product of the Calvin cycle? a G3P (glyceraldehyde-3-phosphate) b Glucose c Oxygen gas 22 Which molecule is regenerated in the Calvin cycle? a NADP+ b RuBP c ADP 23 Which statement best describes the purpose of chromatography in biology? a To measure seed germination b To quantify chlorophyll breakdown c To separate plant pigments for analysis 24 Which pigments usually appear as bands on a chromatogram? a Proteins and lipids b Chlorophylls and carotenoids c Nucleic acids and sugars 25 What is a common solvent system for plant pigment chromatography? a Petroleum ether and acetone or similar mixtures b Water only c Heavy metals 26 In chromatography, what does a higher Rf value indicate? a The pigment absorbed more water b The pigment remained at origin c The pigment traveled farther from the origin 27 Which factor does not affect pigment separation by chromatography? a Pigment solubility b Solvent polarity c Ambient light during development 28 Which component is needed to measure photosynthesis rate directly? a O2 evolution or CO2 uptake b Water intake alone c Soil pH only 29 Which is a primary pigment in photosynthesis besides chlorophyll a? a Ribulose b ATP synthase c Chlorophyll b 30 What is the role of light in photosynthesis? a To excite electrons and drive energy transfers b To burn pigments c To decrease temperature 31 Which organelle contains pigments for photosynthesis? a Chloroplasts b Nucleus c Mitochondria 32 What is the main function of the light reactions?
