How and why would oxygen production change if you placed filters in front of the light source that transmit (a) only red, (b) only infrared, and (c) only green light onto the leaf?arrow_forwardWhat is/are the product(s) of the light capturing reactions of photosynthesis? a) ATP and NAD(P)H O b) ATP only c) ATP and FADH2 d) Glucose and ATParrow_forward
- Photosynthesis ceases when leaves wilt, mainly because(A) the chlorophyll in wilting leaves is degraded.(B) accumulation of CO2 in the leaf inhibits enzymes.(C) stomata close, preventing CO2 from entering the leaf.(D) photolysis, the water-splitting step of photosynthesis,cannot occur when there is a water deficiency.arrow_forwardA) The concentration of CO2 is lower inside a plant cell than in the atmosphere (outside the cell). In your own words, describe how the CO2 levels are kept low inside the plant cell and explain why this is necessary. Assume stomata are open. B) Regarding the situation presented in Part A and assuming that the stomata of the plant leaves are closed, would this favour the induction of photorespiration in a C3 plant? Explain. Make reference to relevant molecule or molecules as needed. Please clearly label your responses as A and Barrow_forwardwhat is the protein complex embedded in the thylakoid membrane that allows protons to flow down their concentration gradient from thylakoid lumen to the stroma? also, the free energy from the flow of protons is used to power which process?arrow_forward
- If you are planning an experiment to show the effect of light on photosynthesis (i) Will you select white light or green light? Justify your answer. (ii) Why would you select a destarched plant.arrow_forwardWhat stages of the light-dependent reactions occur prior to the buildup of hydrogen ions in the thylakoid compartment? Select all that apply. Energy emitted by the electron transport chain triggered by PSII generates a hydrogen ion gradient across the thylakoid membrane. PSII pulls replacement electrons from water molecules, which then break apart into oxygen atoms and hydrogen ions. A photosystem II (PSII) absorbs light energy and releases an electron. Electrons released from PSII enter an electron transport chain in the thylakoid membrane. A flow of hydrogen ions causes ATP synthase to phosphorylate ATP.arrow_forwardAs with plant adaptations againstherbivores, other biological processes can involve multiple levelsof biological organization (Figure 1.3). Discuss examples ofspecialized photosynthetic adaptations involving modificationsat the molecular (Concept 10.4), tissue (Concept 36.4), andorganismal (Concept 36.1) levels.arrow_forward

(A) Chlamydomonas (B) Chlorella (C) Chara (D) Volvoxarrow_forwardA damage in the thylakoid membrane caused the protons to leak into the stroma. Which of the following processes will be most affected? * synthesis of ATP splitting of water absorption of light energy by chlorophyll flow of electrons from PSII to PSIarrow_forwardW hen a culture of Chlamydomonas is exposed to HIGH intensity light, the cells will display negative phototaxis and move away from the light. Which of the following could act as a cellular signal triggering movement away from the light? A. Low levels of P700+ relative to P700 in the chloroplast. B. High levels of G3P in the cytosol. C. High levels of NAD+ relative to NADH in mitochondria. D. Low levels of ATP relative to ADP in the cytosol.arrow_forward
