In gram positive bacteria have a peptidoglycan layer outside of the cell wall. Gram negative bacteria have peptidoglycan between membranes.
The natural penicillin have activity against non beta lactamase producing gram - positive cocci, which includes such as - viridans streptococci, anaerobic streptococcus. Penicillin work indirectly bursting bacteria cell walls. It kills bacteria through binding of that betalactum ring.
Gram positive bacteria have a much thicker layer of peptidoglycan and lack of the protection of an outer membrane. This class , penicillin was first antibiotic to be used widely and prevents the final cross linking step. There are some more classes of penicillin like- natural , penicillin-stable, aminopenicillins and extended-spectrum penicillin.

Answer: If the concentration of glucose inside the cell is higher than the one outside the cell, glucose molecules will move from inside the cell to the outside of the cell in a process of diffusion.
Explanation: Diffusion is the movement of solute molecules from a region of higher concentration to a region of lower concentration. The inside of the cell has higher glucose concentration i.e., has higher quantity of glucose molecules than outside of the cell which has a lower glucose concentration, therefore glucose molecules will move from inside the cell to outside the cell. The purpose of this is to create a balance in glucose concentrations in the two environments.

Biotic factors are the living component of an ecosystem. These include the plants and animals that inhabit the area.
