Biology PHOTOSYNTHESIS REVIEW GAME

Question 1: What is the chemical equation for photosynthesis?

Answer 1: CO 2 + H2O + SL  C 6 H 12 O 6 + O 2

Question 2: What is a stack of thylakoids called?

Answer 2: Grana

Question 3: Out of the 2 reactions of photosynthesis, which one(S) require sunlight?

Answer 3: Only the Light Dependent Reactions require the sunlight to occur.

Question 4: Where do the Light Dependent Reactions take place?

Answer 4 The LDR takes place in the thylakoids of the chloroplasts.

Question 5: What is the most important photosynthetic pigment?

Answer 5 Chlorophyll is the most important pigment found in plants

Question 6 What color is chlorophyll and why?

Answer 6: Chlorophyll is green because when white light (all the colors of the rainbow) shines on the plant, the chlorophyll absorbs all colors, but reflects the green wavelength.

Question 7: What gets broken down in the LDR? What does it get broken down into?

Answer 7: Water gets broken down in the LDR into oxygen, hydrogen ions and electrons

Question 8: What happens to each of the products produced from the splitting of water? Hydrogen ions? Electrons? Oxygen?

Answer 8: The hydrogen ions build up and then travel through the protein channel to help produce ATP. Some hydrogen ions attach to NADP+ becoming NADPH. The electrons refuel those that were lost to the ETC The oxygen is given off as a waste product and is released through the stomata.

Question 9 Is the following anabolic or catabolic? How do you know? ATP  ADP + P + E

Answer 9: Catabolic because bonds are being broken and energy is released.

Question 10: What are the products of the LDR of photosynthesis?

Answer 10: Oxygen NADPH ATP

Question 11 Which of the following are used in the overall reaction for photosynthesis? A. Carbon Dioxide B. Water C. Light D. All of the above

Answer 11: D- All of the above

Question 12: Where does the Calvin Cycle take place?

Answer 12: The Calvin Cycle takes place in the stroma of the chloroplast

Question 13: What will happen to the rate of photosynthesis if the light intensity decreases?

Answer 13 The rate will decrease if the light intensity decreases.

Question 14: Some bacteria, algae and plants are all considered to be?

Answer 14: Autotrophs

Question 14: What are the reactants of the Calvin Cycle?

Answer 15 The Calvin Cycle needs: Carbon dioxide ATP NADPH

Question 16: Name the products of the Calvin Cycle

Answer 16: The Calvin Cycle produces: Glucose ADP +P NADP+

Question 17: Which of the following affects the rate of photosynthesis? A. water B. temperature C. light intensity D. all of the above

Answer 17: D. All of the above

Question 18: Where does the energy come from that fuels the light dependent reactions of photosynthesis?

Answer 18: The Sun

Question 19: Where does the energy come from that fuels the Calvin Cycle?

Answer 19: ATP and NADPH

Question 20: Label all of the following parts:

Answer 20: A. Adenine B. Ribose C. ADP D. ATP E. Adenosine

Question 21: Label the parts below:

Answer 21: 1. Thylakoid 2. Grana 3. Stroma

Question 22:  What is occurring at the arrow?

Answer 22: The electron transport chain

Question 23 At what number would you find water?

Answer 23 2

Question 24: What is the reaction that occurs at 5?

Answer 24 5= Calvin Cycle or Light Independent Reactions

Question 25: Where is the sun represented in this diagram?

Answer 25: 1

Question 26: What would Numbers 9 and 10 represent?

Answer 26: ATP and NADPH

Question 27: What is represented by number 6?

Answer 27: Oxygen

Question 28: What two wavelengths (colors) of light are most useful for photosynthesis?

Answer 28 Best= violet/blue 2 nd best=red

Question 29 How would you define the process of photosynthesis?

Answer 29: The process in which autotrophs use carbon dioxide and water and convert the energy of sunlight into chemical potential energy stored in glucose.

Question 30 Why would temperature affect the rate of photosynthesis?

Answer 30 The enzymes used in photosynthesis would not work as well if they were not at the optimal temperature.

Question 31 What is a pigment?

Answer 31 A substance that absorbs or reflects light

Question 32 True or false: During the Calvin Cycle, water gets split?

Answer 32 False- it occurs in the LDR

Question 33 What is the energy generated from the ETC used for?

Answer 33 To actively transport the hydrogen ions across the thylakoid membrane from a low concentration to a high concentration.

Question 34 What is happening at the indicated arrow?

Answer 34: Hydrogen ions are flowing through the ATP Synthase. As they flow through, it causes it to turn like a water wheel or turbine. This is a source of energy and that energy is used to put the P back onto ADP to form ATP.

Question 35 What does #7 represent?

Answer 35 Glucose/sugar

Question 36 Energy is released from ATP when?

Answer 36: The bond is broken between the 2 nd and 3 rd phosphate

Question 37 Our cells can regenerate ATP from ADP by?

Answer 37 Using the energy from the food we eat.

Question 38 What are Photosystems?

Answer 38 Clusters of chlorophyll and other pigments that collect sunlight

Question 39 Use the picture to answer the question. What happens to the hydrogen ions from the splitting of water?

Answer 39 The get released inside the thylakoid

Question 40 As H+ move through the ATP synthase, their energy is used to?

Answer 40 Convert ADP into ATP

Question 41 The energy to make high energy sugars in the Calvin Cycle comes from?

Answer 41 ATP and NADPH
