Lab VII: Barophiles - correct answer live in high barometric pressure env. Lab VII: Aerobic Respiration - correct answer with oxygen Lab VII: Photosynthesis - correct answer plants use to generate energy - use light and water Lab VII: Fermentation - correct answer no oxygen Lab VII: Anaerobic Respiration - correct answer no oxygen Lab VII: Chemolithotrophy - correct answer inorganic compounds as energy and electron source Lab VII: Describe organisms in regard to their oxygen requirements and metabolism: Obligate Anaerobe = Obligate Aerobe = Facultative Anaerobe = Microaerophile = ` - correct answer Obligate Anaerobe = survive in NO O2 conditions, die in O2 presence Obligate Aerobe = require O2 Facultative Anaerobe = use aerobic respiration in presence of O2, but use fermentation or anaerobic resp. w/o O2 Microaerophile = require O2, but at reduced levels Lab VII: What kind of bacteria grew under each of the given conditions: 1. Ambient Air 2. Candle Jar 3. Gas Pak - correct answer 1. Normal atmospheric air = Obligate Aerobe (best), facultative anaerobe
