Cell (biology) made up of cellulose, fungi cell walls are made up of chitin and bacteria cell walls are made up of peptidoglycan. A gelatinous capsule is present in some bacteria outside the cell membrane and cell wall. The capsule may be polysaccharide as in pneumococci, meningococci or polypeptide as "Bacillus anthracis" or hyaluronic acid as in streptococci. Capsules are not marked by normal staining protocols and can be detected by India ink or methyl blue; which allows for higher contrast between the cells for observation. Flagella are organelles for cellular mobility. The bacterial flagellum stretches from cytoplasm through the cell membrane(s)
Glucose test and oral glucose tolerance test (OGTT) should be done for high-risk individuals (old people, those with high blood pressure etc.). 6.1–6.9 mmol/l (110–125 mg/dl) means OGTT should be done even if other indicators of diabetes are not present. 7 mmol/l (126 mg/dl) and above indicates diabetes and the fasting test should be repeated. Glucose test Many types of glucose tests exist and they can be used to estimate blood sugar levels at a given time or, over a longer period of time, to obtain average levels or to see how fast body is able to normalize changed glucose levels.
