#Applied Microbiology

Match the metabolic process in Column I with its correct characteristic or location in Column II.

Column IColumn II
A. Glycolysis1. Generates ATP via Oxidative Phosphorylation using oxygen as the final acceptor.
B. Krebs Cycle (Citric Acid Cycle)2. Occurs in the Cytoplasm; produces ATP via Substrate-level phosphorylation.
C. Electron Transport Chain3. Occurs in the Mitochondrial Matrix; produces GTP/ATP via Substrate-level phosphorylation.

#Question id: 40184

#Applied Microbiology

Choose the correct option regarding the bacterial cell wall.

Assertion (A): N-acetylmuramic acid (NAM) is a crucial component of the bacterial cell wall found in both Gram-positive and Gram-negative bacteria.

Reason (R): NAM residues serve as the attachment point for the peptide chains that cross-link the peptidoglycan layers.

#Applied Microbiology

Read the following statements regarding the bacterial cell envelope:

Statement I: The outer membrane of Gram-negative bacteria contains Lipopolysaccharides (LPS), which consists of Lipid A, Core polysaccharide, and O-antigen.

Statement II: Lysozyme breaks down the bacterial cell wall by cleaving the glycosidic bond between Lipid A and the Core polysaccharide.
