Homework Answers
The correct option is c - biochemical tests
Biochemical tests are used for microbial identification. Biochemical tests are tests used to identify unknown bacteria depending on the differences in biochemical activities. Metabolic profiles are different from one species of bacteria to another. Each species of bacteria has a unique set of enzymes involved in biochemical reactions. Biochemical tests identify the bacteria by determining the enzymes and biochemical reactions that are unique to each species of bacteria. It helps the physicians to treat the patient correctly by identifying the pathogen. Some biochemical tests are methyl red test, carbohydrate fermentation test, citrate utilization test, Indole test, catalase test, hydrogen sulfide test, etc.

Which of the following is the best definition of the term amphibolic pathway? An amphibolic pathway is one that functions simultaneously in catabolism and anabolism. An amphibolic pathway is a pathway that is found in both humans and bacteria. An amphibolic pathway is one that can catabolize both pentose and hexose sugars. An amphibolic pathway is one that generates ATP using both substrate level phosphorylation and oxidative phosphorylation. Choose the true statement(s) about biochemical tests. To be marked correct, you'll...
