Question

Negatively charged molecules that are partially responsible for the negative charge of the gram-positive bacterial cell surface are _______.

Answer 1

Answer:

Teichoic acids

Explanation:

Teichoic acid has a negative charge  due to the presence of phosphate in their structure. Since Teichoic acids forms part of Bacterial cell wall where it is linked to the underlying peptidoglucan or plasma membrane. This gives the Gram Positive bacteria a negative charge.

The negative charge makes the Teichoic acid to serve as a Cation sequestering mechanism

Gram negative cell wall does not contain teichoic acids. .

Answer 2

Answer: They are called Teichoic acids.

Explanation:

Teichoic acids are polymer that are rich in posphate present in gram positive bacteria. Techoic are negatively charged and there presence in the peptidoglycan wall or plasma cell make the gram positive to have a negative charged bacteria cell. Teichoic acids are negatively charged due to the phosphate structure. They function in determine bacteria cell wall and cell division. Examples of gram positive bacteria with teichoic acids is staphylococcus.
