Metabolism Quiz Questions With Complete Solutions

What are the two types of metabolism? correct answer: Catabolism and anabolism Catabolic metabolism correct answer: -Use large molecules to break them down into small molecules and produce energy -Product of one reaction serves as the substrate for the next -Usually molecules that are rich in C N O because those are essential for microorganisms Anabolic metabolism correct answer: Small molecules and energy to synthesize large molecules Amphibolic pathways correct answer: glucose to pyruvate and back to glucose What are the types of microbial work that cells do? correct answer: Chemical, mechanical, and transport Chemical work correct answer: Metabolism Mechanical work correct answer: important in terms of motility, capacity to move Transport work correct answer: Secretion systems, ways they absorb nutrients and expel waste/metabolites What does microbial cell work use for energy? correct answer: Use energy in form of ATP ATP is produced by... correct answer: Aerobic respiration, anaerobic respiration, fermentation, phototrophy, and chemolithotrophy What are produced by chemoorganotrophs? correct answer: Aerobic, anaerobic respiration and fermentation, use organic molecules What are produced by phototrophs? correct answer: Phototrophy- use light to produce energy What are produced by chemolithotrophs? correct answer: Chemolithotrophy- use inorganic molecules Catabolism and energy release and conservation correct answer: -the product of one reaction serves as the substrate for the next -requirements for C, H, and O What are the basic needs that all organisms and microorganisms have? correct answer: -ATP as an energy currency -reducing power to supply electrons for chemical reactions
