MacConkey agar uses lactose as a differential agent, however it is not as specific as an EMB test in terms of types of coliforms detected. This makes the MacConkey test useful in a clinical setting but not necessarily useful in environmental microbiology. Could MacConkey agar be altered by using a carbohydrate other than lactose for differentiation

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !

hey, what do you need . just post the question and i may be able to you : )
