Question

question 1 (1 point)
what type of macromolecule are enzymes?
○ carbohydrate
○ lipid
○ protein
○ nucleic acid
question 2 (1 point)
which enzyme is required to utilize citrate in simmons citrate agar?
○ catalase
○ tryptophanase
○ citrate permease
○ beta - galactosidase

Explanation:

• Enzymes are biological catalysts. Most enzymes are proteins. Proteins are made up of amino acids linked by peptide bonds.
• In Simmons Citrate Agar, citrate permease is the enzyme that allows bacteria to take up citrate (a source of carbon and energy). Catalase breaks down hydrogen peroxide. Tryptophanase acts on tryptophan. Beta - galactosidase acts on beta - galactosides.

Answer:

Question 1: protein
Question 2: Citrate permease
