Biology 20 - Chapter 5 Assignment - Photosynthesis and Cellular Respiration 12. The presence of pigments other than chlorophyll in plants is important because they A. are used to build chlorophyll B. can use oxygen to carry out photosynthesis C. function in exactly the same way as chlorophyll D. allow the plant to utilize wavelengths of light other than those used by chlorophyll 13. During photosynthesis, in which part(s) of the electromagnetic spectrum does the greatest absorption of light occur? A. green B. yellow C. red and blue D. red and yellow 14. What term is used to describe an electron that has been raised to a higher energy level? A. hyper B. excited C. boosted D. captured 15. Energy from sunlight is trapped by chlorophyll which is located in A. the Krebs cycle B. the mitochondria C. the electron transport system D. the thylakoid membranes of chloroplasts 16. The conversion of light energy into chemical energy requires A. oxygen B. glycogen C. mitochondria D. carbon dioxide 17. The process of photolysis (the splitting of water) to release hydrogen ions, electrons, and oxygen occurs during A. the light-dependent reactions B. the Calvin Benson cycle C. photorespiration D. carbon fixation Search

Step 1
- The correct answer is D. allow the plant to utilize wavelengths of light other than those used by chlorophyll. This is because different pigments absorb different wavelengths of light, allowing plants to capture more of the sun's energy than they could with Show more…

5) The oxygen released by photosynthesis is produced by which of the following processes? A) splitting water molecules B) chemiosmosis the electron transfer system of photosystem C) the electron transfer system of photosystem II 6) Which of the following statements correctly describes the distinction between autotrophs and heterotrophs? A) Cellular respiration is unique to heterotrophs B) Only heterotrophs have mitochondria Autotrophs, but not heterotrophs, can nourish themselves beginning with CO2 and other nutrients that are inorganic. D) Only heterotrophs require oxygen. 7) Use the following figure to answer the question: 1 400 500 600 700 Wavelength of light (nm) The figure shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis. Why are they different? A) Green and yellow wavelengths inhibit the absorption of red and blue wavelengths. Oxygen given off during photosynthesis interferes with the absorption of light. Other pigments absorb light in addition to chlorophyll. D) Anaerobic bacteria take up oxygen, which changes the measurement of the rate of photosynthesis.

A) What is the relationship between photosynthesis and cell respiration? 1. Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. 2. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food. B) What color found in many plants is produced by which pigment? C) What color of light are green plants the best at reflecting? 1. Yellow 2. Green 3. Blue 4. Red D) What are the two main sets of reactions in photosynthesis? 1. Light-dependent reactions and Calvin cycle reactions. 2. Thylakoids and grana 3. NADPH producing photosystem and water splitting photosystem 4. Chlorophyll and carotenoid pigments. E) Organisms that are able to do photosynthesis are called? 1. Heterotrophs 2. Chemotrophs 3. Autotrophs F) Where is ATP actually made during the process of photosynthesis? 1. By photosystem I 2. In the Calvin cycle 3. At or by an enzyme in the thylakoid membrane 4. In an electron. G) What would be the effect of a substance that makes the thylakoid membrane totally and openly permeable to H+? 1. More sugar is made. 2. Less NADP+ is reduced. 3. Less oxygen is released. 4. Less ATP is made. Chlorophyll pigments absorb what wavelengths? 1. Wavelengths corresponding to green light. 2. Wavelengths corresponding to red and blue light. 3. Wavelengths smaller than the visible spectrum. 4. Wavelengths larger than the visible spectrum. Ribulose 1,5-bisphosphate, also called rubisco, is used by plants to do what?
