5 Questions
Match the following terms with their descriptions:
Photosynthesis = Biological process converting light energy into chemical energy Oxygenic photosynthesis = Produces oxygen as a byproduct and stores chemical energy in carbohydrate molecules Photoautotrophs = Organisms that perform photosynthesis Anoxygenic photosynthesis = Uses bacteriochlorophyll to split hydrogen sulfide as a reductant instead of water
Match the following organisms with their ability to perform photosynthesis:
Plants = Perform photosynthesis Algae = Perform photosynthesis Cyanobacteria = Perform photosynthesis Bacteria using bacteriochlorophyll = Perform anoxygenic photosynthesis
Match the following compounds with their role in photosynthesis:
Sugars, starch, glycogen, cellulose = Store chemical energy produced in photosynthesis Carbon dioxide and water = Reactants in endergonic reaction during photosynthesis Hydrogen sulfide = Used as a reductant in anoxygenic photosynthesis Sulfur = Produced as a byproduct in anoxygenic photosynthesis
Match the following concepts with their relation to photosynthesis:
Oxygen content of Earth's atmosphere = Largely maintained by photosynthesis Biological energy necessary for complex life on Earth = Supplied by photosynthesis Non-carbon-fixing anoxygenic photosynthesis = Performed by certain archaea using retinal and microbial rhodopsin derivatives Adenosine triphosphate (ATP) synthesis = Directly powered by proton pumps in certain anoxygenic photosynthesis
Match the following terms with their primary role in photosynthesis:
Chlorophyll = Captures light energy for use in photosynthesis Carotenoids = Accessory pigments that assist in capturing light energy for photosynthesis Retinal and microbial rhodopsin derivatives = Used to absorb green light and power proton pumps in certain anoxygenic photosynthesis ATP synthase = Enzyme responsible for synthesizing ATP during cellular respiration
Test your knowledge about the biological process of converting light energy into chemical energy in organisms, and how the energy is stored in organic compounds for cellular activities.
