Some bacteria are mixed with milk to make yogurt.
Amount of Lactic Acid
These bacteria change the lactose in the milk into
Produced by Different Bacteria glucose, which then ferments into lactic acid. The
lactic acid causes the protein in the milk to stick
together, creating the gelatinous yogurt. The adjacent graph shows the relative lactic acid
production of different bacteria.
Which of these is a logical conclusion based on the
given data?
a) Bacterium 2 makes glucose but not lactic acid
and, therefore, should not be used in making yogurt
b) Bacterium 3 is least effective at changing lactic
acid into glucose and, therefore, should not be used in making yogurt.
c) Bacteria 1 & 2 combine to make the largest
amount of lactic acid and, therefore, would be most
effective at making yogurt.
d)Bacteria 1 & 3 combine to be most effective at breaking down the glucose needed to make yogurt.
