Question

which of the following statements regarding the bacterial sacculus are true? choose one or more: a. the crucial cross-linking reactions occur inside the cell (i.e., in the cytoplasm). b. it is composed of peptidoglycan. c. it is also known as the cell wall. d. it provides protection from osmotic rupture. e. it is impervious to polar or charged molecules.

Answer 1

Answer: b, d.

Step-by-step explanation:

b. The bacterial sacculus is composed of peptidoglycan, which is a polymer made up of sugars and amino acids. It forms a mesh-like structure that surrounds the cell and provides strength and stability to the cell.

d. The bacterial sacculus provides protection from osmotic rupture by helping to regulate the pressure inside the cell and maintain the appropriate osmotic balance between the inside and outside of the cell.

The other statements are not entirely true:

a. The assembly of peptidoglycan and cross-linking reactions can occur both inside and outside the cell.

c. The bacterial sacculus is commonly referred to as the cell wall, although it is not the only component of the cell wall.

e. The bacterial sacculus is semi-permeable and allows some polar or charged molecules to pass through, but not all.
