Glucose is the most readily available compound for the process of cellular respiration and obtaining energy from food. Bacteria do not have a digestive system. Bacteria secrete, or give off, the enzymes needed to digest their food. The food is broken down extracellularly. Then the bacterium can absorb the pre-digested food.
Fungi also digest their food in the same way.
The purpose of this lab is contained within the Introduction section. Determine what it is and write it in your logbook. At your own lab station, mass out 1 gram of your own compost soil and add this to 99 ml of sterile distilled water that you premeasured and put in a flask for sterilization previously. Mix by swirling at your lab desk. On lab day, make notes on pipette sterility in logbook at the beginning of your observations section.
