A lowering of the dissolved oxygen would be an indication of that happening and that would be the primary thing that i would look for

Which microbes spoil food?
Microbes are all around us - in the air, the soil, water and our bodies. This means they can soon get into food and, if the conditions are right, multiply rapidly. Unfortunately, when certain microbes grow on food, it soon begins to smell nasty, look slimy, change colour, taste awful or even acquire a furry coating. The food 'goes off' - it is spoiled. Even though it may not harm us, it is inedible and must be thrown away. There is also a chance that pathogenic microbes are present along with the spoilers.
Does the active site of an enzyme have a shape that is specfic for its given substrate?
Yes all enzymes have an active site where substance are temporarily bound. All enzymes have shape that may change during catalysis. The active site of an enzyme orients its substrate molecules, thereby promoting interaction of their reactive parts.
What happens when globular proteins are denatured?
enzymes change shape/ unfolding of proteins
What blocks enzyme activity by binding to allosteric site of an enzyme causing the enzyme's active site to change shape?
An allosteric inhibitor stops enzyme activity by binding to an allosteric site and causing the conformation of the enzyme to change.
How are they different between active immunity and passive immunity different?
Passive immunity involves the bodies defenses which do not change for different types of microbes. This would be like Natural Killer B cells which attack a wide variety of microbes. Active immunity involves your body becoming acclimated toward a bacteria or virus, such that future contact will spur on a triggered response. An example of this would be the production of antibodies.
