When a Bacillus Anthracis Population Suddenly Must Form Spores to Survive

question 76

Multiple Choice

When a Bacillus anthracis population suddenly must form spores to survive a harsh nutrient poor environment, how do the cells obtain energy?

• A) Cells in a growth phase that have not used up all of their energy will be the only ones to make endospores, which is why relatively few endospores are often made from a large population.
• B) Intracellular energy reserves are quickly made available to produce endospores.
• C) Slow responding cells are cannibalized by others that already began spore formation.
• D) Global regulation is initiated to minimize energy waste in biosynthetic pathways and catabolic pathways are increased to consume remaining usable substrates to fuel spore formation.
