The chemical groups can the bacteriophage specific for Gram-positive cells attach. Introduction: Virus is a small infectious agent that only replicates inside the living cells of an organism. It is made up of a core of genetic material, either RNA or DNA surrounded by a protective coat called capsid. A bacteriophage is a virus that infects and replicates within archaea and bacteria. Bacteriophage infects bacteria but is harmless to humans.

Expert Solution & Answer

Explanation of Solution

Bacteriophage recognizes its host by its tail fibers binding to the chemical groups connected with receptors on the host cell surface. Other functions for the bacterial cells are also performed by these receptors. For example, lipopolysaccharide and pili in gram-negative bacteria and teichoic acids in Gram-positive bacteria. The teichoic acids are present in cell walls of most Gram-positive bacteria. It is a polymer of glycerol-phosphate or ribitol phosphate that can bind to the cytoplasmic membrane or peptidoglycan covalently. The teichoic acid is accountable for a net negative charge on Gram-positive cells and it functions in peptidoglycan expansion during growth of cell.

Explain down bellow what happens to the cell: Decreased pH in mitochondria Increased ATP Decreased pH in cytosol Increased hydrolysis Decreasing glycogen and triglycerides Increased MAP kinase activity Poor ion transport → For each one:→ What normally happens?→ What is wrong now?→ How does it mess up the cell?

An 1100 pound equine patient was given 20 mg/kg sucralfate 3 times a day, 2.8 mg/kg famotidine twice a day, and 10mg/kg doxycycline twice a day. Sucralfate comes as a 1 gm tablet, famotidine as 20 mg tablets, and doxycycline as 100mg tablets. All are in bottles of 100 tablets.How many total mg are needed for the patient and how many tablets of each would be needed to provide each dose?How many bottles of each would be needed to have available if this patient were to be on this drug regimen for 5 days?

The patient needs a solution of 2.5% dextrose in Lactated Ringer’s solution to run at 75 ml/hr for at least the next 12hours. LRS comes in fluid bags of 500 ml, 1 Liter, 3 Liters and 5 Liters. How can a 2.5% solution be made by adding50% dextrose to the LRS?
